Section – B [Strategic Management]
◉ Module 8 = Introduction
◉ Business strategy:
1. It is about how to compete successfully in particular markets.
2. It emphasizes improvement of the competitive position of a organization’s products or services
in the specified industry or market segment served by that business unit.
3. These strategies fit within the two overall categories, namely, competitive andcooperative
strategies.
◉ Functional strategy or Operational Level Strategy:
1. It is concerned with how the component parts of an organization deliver effectively the
corporate and business level strategies in terms of resources, processes and people.
2. It is concerned with developing and nurturing competence to provide a business unit with
a competitive advantage. These strategies are taken at the functional level directed towards
maximizing resource productivity.
Red Oceans –
• Red oceans represent all the industries that are currently in existence and are the known market
space.
• In the red oceans, industry boundaries are defined and accepted, and the competitive rules of the
game are known.
• In a red ocean market or a red ocean strategy, there is a concentrated market and will be highly
competitive.
• These are normally found by the small but unpopular market.
• In a red ocean market, the competition would normally be high, and the existing companies
compete with each other using competitive methods.
• One of the examples of a red ocean company can be different automobile companies. All the
various companies are competing with each other to solve the same problem, or the demand faced
by the consumers. A red ocean market is highly competitive and would be riskier for a new company
especially a startup.
Blue Oceans –
• The concept of Blue Ocean Strategy was first coined by W. Chan Kim and Renee Mauborgne in their
book
• According to them Blue oceans denote all the industries which are currently not existence and
remain unexplored, unknown and untainted by competition.
• A blue ocean strategy is focused more on the new trends and demands of the consumers in creating
a new market based on it.
• Blue oceans are a more unoccupied market and not much known. The blue ocean market is mostly
concentrated on providing value and is created based on that.
• In the blue ocean strategy, a new product or service is created which is not available in the market
which would solve a problem that is already there in the market. The blue ocean market pays a lot
of attention to value and innovation aspects.
Strategic Management
1. It refers to a set of managerial decisions and actions that determines the long term performance of
an organisation.
2. Originally called ‘corporate planning’, the shift from ‘corporate planning’ to what became termed as
‘strategic management’ was associated with increasing focus on competition.
Strategic
Management
Environmental scanning:
1. It refers to the monitoring, evaluating and disseminating of information from the external and
internal environments to key people within the organisation.
2. The purpose is to identify the strategic factors both internal and external elements that will shape
the future of the organisation.
3. The range of methods and techniques available for environmental scanning is wide.
Strategy Formulation:
1. It refers to the development of long range plans for the effective management of environmental
opportunities and threats, in the light of corporate strengths and weaknesses (SWOT).
2. It includes defining the mission, setting objectives, developing strategies and setting policy
guidelines.
Strategy Implementation:
1. It is the process by which strategies and policies are put into practise though the development of
programs, budgets and procedures.
2. This includes day to day decisions in resource allocation and is typically conducted by the middle
and lower level managers with review by the top management.
3. It involves taking actions at the functional, business and corporate levels to execute a strategic plan.
4. Implementations include, for example, putting quality improvement programs, changing the way
product is designed, positioning the product differently, market segmentation, expanding through
mergers and acquisitions and downsizing the company.
Mission includes
∙ A definition of products and services the organisation provides.
∙ Technology used to provide these products and services.
∙ Types of markets
∙ Customers need or requirement
∙ Distinctive Competencies
1. The mission of a business is the fundamental, unique purpose that sets it apart from other
firms of its type and identifies the scope of its operations in product and market terms.
2. In short, the mission describes the product, market, and technological areas of emphasis
for the business in a way that reflects the values and priorities of the strategic decision
makers.
Organisational culture:
Organisational culture is the ‘basic assumptions and beliefs that are shared by members of an organisation,
that operate unconsciously and define in a basic taken-for-granted fashion an organisation’s view of itself
and its environment’. Related to this are taken-for-granted ways of doing things, the routines that
accumulate over time. In other words, culture is about that which is taken for granted but none the less
contributes to how groups of people respond and behave in relation to issues they face. It therefore has
important influences on the development and change of organisational strategy.
Strategic Leadership
It is about how to effectively manage a company’s strategy making process to create competitive
advantage. Strategic leaders must strive towards maximising shareholders value by balancing the profit
growth and profitability of the organisation. Some of the key qualities that a strategic leader is expected to
have are as follows:
1. Strategic leader should be a visionary. He should have a strong sense of direction and a clear and
compelling vision of where the organisation should go.
2. A good strategic leader must have the ability to identify and articulate the business model the
organisation will use to attain the vision. This requires a fit between the organisational strategies
with the organisational vision.
3. A good strategic leader should demonstrate a sense of commitment towards the vision and the
business model through his actions and words.
4. He should develop a strong network of both formal and informal sources to remain well informed
about whatever is happening in and around the organisation.
5. A good strategic leader should be able recognise and empower subordinates to make decisions.
This not only acts as a motivator for the subordinates but also relives the leader from being
overloaded with responsibilities.
6. In this process of delegation, the strategic leader may delegate many important responsibilities to
his subordinates but he will not delegate those which are of critical importance to the success of
the organisation. A good strategic leader should try to develop a consensus for his ideas among his
subordinates rather than attempt to use his authority to force the ideas through.
Organizational Change
In any business environment, change should happen. It shows one’s commitment to the kind of growth and
evolution it takes to stay modern, relevant, and competitive. Countless factors make change inevitable. But what
kind of change we are thinking about is important. Change can include things like:
◉ Introducing new software or updating marketing practices
◉ Updated business processes
◉ A full-on restructuring
◉ Leadership changes
◉ Updated thinking
◉ New project management tools
◉ Budget constraints
◉ Shifts in strategy
There are countless organizational change management (OCM) methods. Each involves a basic series of steps or
practices that could be linear or cyclical in approach. Some of the most popular methods include:
◉ Kotter 8-Step Process for Leading Change: Create → Build → Form → Enlist → Enable → Generate → Sustain →
Institute
◉ McKinsey & Company’s 7-S Framework: Style, Skills, Systems, Structure, Staff, and Strategies = Shared Values &
Goals
◉ Kurt Lewin’s Change Model: Unfreeze → Change → Refreeze
◉ ADKAR Model: Awareness → Desire → Knowledge → Ability → Reinforcement
◉ The Kubler-Ross Model: Shock → Anger → Bargaining → Depression → Acceptance
◉ Satir Change Management Model: Late Status Quo → Resistance → Chaos → Integration → New Status Quo
◉ William Bridges’ Transition Model: Ending → Neutral Zone → New Beginnings
However, there is no right or wrong in terms of which method to choose. Any method can facilitate smooth
transitions and positive change. The best method depends on the organisation and stakeholder needs and
preferences. Methods are generally seen as interchangeable.
SMART
To create effective objectives, make sure they’re specific, measurable, attainable, relevant and time-based. These
guidelines are often abbreviated using the acronym SMART. Here are more details regarding the SMART goal
framework:
◉ Specific: Specific goal provides the employee with the exact result needed for their performance to be
successful. A clear objective can optimize productivity and effectiveness.
◉ Measurable: Successful goals can usually be measured using metrics that determine an employee’s success or
progress. A quota, for example, is one way to measure an employee’s success.
◉ Attainable: Effective goals are often those which are ambitious and also possible to achieve. Consider if and
how an employee can attain their objectives with the tools and resources available to them within a specified
time frame.
Performance objectives
Performance objectives for employees are set so that they can know what is expected of them and understand what
they are accountable for. They can be performance-based, or they can be development-led. The following are some
of the examples of performance objectives for employees.
◉ Productivity: This has to do with the amount of work that an employee is expected to perform within a specific
time. This is one of the most important performance objectives for employees. In the service industry such as
banking, this could be the number of clients that a service consultant has assisted. This helps to increase
productivity within a business, and it can increase sales and revenue.
◉ Quality and efficiency: This has to do with the manner of performing activities. It takes productivity further to
deal with how fast the worker can perform a task. This measure also takes quality into consideration. Not only
should the service be fast, but it must be of good quality. This is one of the most vital performance objectives
for employees because it makes them pay more attention to the quality of their work which reduces human
error while increasing productivity. ‘
◉ Education and self-development: This performance objective for employees considers the needs of workers. It
focuses on the goals workers set to develop themselves. It can include things such as an employee learning a
new skill, doing a new course or simply job-shadowing someone. This makes workers more valuable due to
continuous growth in their respective fields. This also encourages employers to see how committed workers
are to their own growth and personal development
2. The transition from accounting profit to economic profit was triggered due to a major problem of
accounting profit as it combines two types of returns: the normal return to capital that rewards
investors for the use of their capital; and economic profit, which is the pure surplus available after
all inputs (including capital) have been paid for.
3. Economic profit represents a purer and more reliable measure of profit that is a better measure of
performance. In order to distinguish economic profit from accounting profit, economic profit is
often referred to as rent or economic rent.
4. A widely used measure of economic profit is economic value added (EVA), devised and popularised
by the New York consulting firm Stern Stewart & Company.
Cost of capital is calculated as: capital employed multiplied by the weighted average of capital
(WACC).
6. Economic profit has two main advantages over accounting profit as a performance measure.
◉ First, it sets a more demanding performance discipline for managers. As Stern Stewart’s
calculations show, many major corporations’ apparent profitability disappears once cost of
capital is taken into account.
◉ Second, using economic profit improves the allocation of capital between the different
businesses of the firm by taking account of the real costs of more capital intensive businesses.
• Environmental scanning:
• Strategy Formulation:
1. It refers to the development of long range plans for the effective management
of environmental opportunities and threats, in the light of corporate strengths
and weaknesses (SWOT).
2. It includes defining the mission, setting objectives, developing strategies
and setting policy guidelines.
• Strategy Implementation:
1. It is the process by which strategies and policies are put into practise though the
development of programs, budgets and procedures.
2. This includes day to day decisions in resource allocation and is typically
conducted by the middle and lower level managers with review by the top

3. It involves taking actions at the functional, business and corporate levels to
execute a strategic plan.
4. Implementations include, for example, putting quality improvement programs,
changing the way product is designed, positioning the product differently,
market segmentation, expanding through mergers and acquisitions and
downsizing the company.
• Evaluation and control:
It involves the process through which organisational activities and performances are
monitored. The actual performances are compared to the desired performances and
corrective actions are taken to resolve problems. The process of evaluation and
control helps to identify the weakness and lacunae of the previously implemented
strategic plan and thereby, stimulates the entire process to begin again
Introduction
1. Business environment refers to the sum total of all the conditions, events and influences in and
around an organization that affects it hence, a clear understanding of business environment is of
crucial importance.
2. The very survival of an organization depends on its environment. However, the environment is also
the source of threats for example, hostile shifts in market demand, new regulatory requirements,
innovations in technology or the entry of new competitors.
3. Environmental change can be both an opportunity as well as a threat to an organization.
4. It is vital that managers analyses their environments carefully in order to anticipate and if possible
influence environmental change.
• Industry, or sector, forms the next layer with this broad general environment. This is made up of
organisations producing the same products or services.
• Competitors and markets are the most immediate layer surrounding organisations. Within most
industries or sectors there will be many different organisations with different characteristics and
competing on different bases, some closer to a particular organisation, some more remote.
2. Environment is dynamic: The changing nature of environment is a constant. The dynamism of the
environment is largely due to large number of factors that continuously influences its character and
shape.
3. Environment is Multi-faceted: The perception of the observer is very important to determine the
Copyright@DEEPAKCLASSES DEEPAK CLASESS – Youtube Channel
shape and character of thee environment. Changes in the environment may be perceived differently
by different individual. The changes and developments may be considered to be an opportunity to one
and a threat to others.
4. Environment has a far reaching impact: The impact of environment on an organisation is huge. It
critically underpins the growth and profitability of an organisation. Any changes in the environment
affect the organisation in more ways than one. The very survival and existence of an organisation is
critically dependent on its environment.
PESTEL
The PESTEL framework is an extension of the PEST strategic framework, one that includes additional
assessment of the Environmental and Legal factors that can impact a business. The PESTEL framework
shows some of the macro-environmental influence which might affect organizations. It focuses on
the six principal components of strategic significance in the macro-environment namely, political,
economic, social, technology, environmental and legal forces.
◉ Economic Factors
These factors are determinants of an economy’s performance that directly impacts a company and have
resonating long term effects. For example, a rise in the inflation rate of any economy would affect the
way companies price their products and services. Adding to that, it would affect the purchasing power of
a consumer and change demand/supply models for that economy. Economic factors include inflation
rate, interest rates, foreign exchange rates, economic growth patterns, etc. It also accounts for the FDI
(foreign direct investment) depending on certain specific industries who’re undergoing this analysis.
◉ Socio-cultural factors
These factors scrutinize the social environment of the market, and gauge determinants like cultural
trends, demographics, population analytics, etc. An example of this can be buying trends for Western
countries like the US where there is high demand during the Holiday season.
◉ Technological factors
These factors pertain to innovations in technology that may affect the operations of the industry and the
market favorably or unfavorably. This refers to automation, research and development, and the amount
of technological awareness that a market possesses.
◉ Environmental factors
They include protection laws, waste disposal, energy consumption, weather, climate, climate
change and associated factors like water shortages. These factors can directly impact industries
such as insurance, farming, energy production, and tourism. They may have an indirect but
substantial effect on other industries such as transportation and utilities.
◉ Legal
These factors have both external and internal sides. There are certain laws that affect the business
environment in a certain country while there are certain policies that companies maintain for
themselves. Legal analysis takes into account both of these angles and then charts out the strategies in
light of these legislations. For example, consumer laws, safety standards, labor laws, etc.
◉ The framework must not be used just to give a snapshot in time. It is important not just to
describe these forces but also to understand how they can be countered and overcome in the
future.
◉ These competitive forces will not only be subject to steady changes into the future but, more
importantly, the discontinuities caused by changes in the macro-environment.
◉ The five forces are independent of each other. Pressures form one direction can trigger off
changes in another in a dynamic process of shifting sources of competition.
◉ Competitive behaviour may be concerned with disrupting these forces and not simply
accommodating them.
The five forces are discussed hereunder: Risk of Entry by Potential Competitors
Threat of entry will depend on the extent to which there are barriers to entry. Barriers to
entry are factors that need to be overcome by new entrants if they are to compete
successfully. These should be seen as providing delays to entry and not as permanent
barriers. The typical barriers are:
Economies of Scale
Economies of scale arise when unit costs fall as a firm expands its output. Sources of scale
economies include cost reductions gained through mass producing a standardised
commodity, discounts on bulk purchases of raw material inputs and component parts,
the advantages gained by spreading fixed production costs over a large production
volume and the cost savings associated with spreading marketing and advertising costs
over a large volume of output. If theses cost advantages are significant then a new
company that enters the industry and produces on a small scale suffers a significant cost
disadvantage relative to established companies.
Brand Loyalty
Brand loyalty exists when consumers have a preference for the products of established
companies. A company can create a brand loyalty through continuous advertising of its
brand-name products and company name, patent protection of products, product
innovation achieved through company research and development programs, an
emphasis on high product quality and good after sales service.
(a) superior production operations and processes due to accumulated experience, patents,
or secret processes,
(b) control of particular inputs required for production, such as labour, materials, equipment,
Copyright@DEEPAKCLASSES DEEPAK CLASESS – Youtube Channel
or management skills, that are limited in their supply; and
(c) access to cheaper funds because existing companies represent lower risks than new
entrants. If established companies have absolute cost advantages, the threat of entry as a
component of five forces is weaker.
Government Regulation
Legal restraints on competition vary from patent protection, to regulation of markets, through to
direct government action. Of course, managers in the hitherto protected environments might face
the pressures of competition for the first time if governments remove such protection. Historically,
government regulation has constituted a major barrier into many industries
Competitive Rivalry
Competitive rivals are organisations with similar products and services aimed at the same
customer group. The competitive struggle can be fought using price, product, design,
advertising and promotion spending, direct selling efforts, and after-sales service and
support. More intense rivalry implies lower prices or more spending on non-price
competitive weapons or both. The intensity of rivalry among established companies
within an industry is largely a function of the factors such as:
(i) The balance between the competitor
(i) The level of industry demand
(ii) In industries where fixed costs are high
(iii) If the addition of extra capacity is in large increments
(iv) The level of differentiation plays an important role.
(v) Exit barriers are economic, strategic and emotional factors that prevent companies
from leaving an industry.
(i) The product or service that the industry supplies comprise a large number of small operators.
Copyright@DEEPAKCLASSES DEEPAK CLASESS – Youtube Channel
(ii) There is a concentration of buyers, particularly if the volume purchases of the buyers are high.
(iii) When the supply industry depends on the buyers for a large percentage of its total orders.
(iv) There are alternative sources of supply, perhaps because the product or service requires is
undifferentiated between suppliers or when the deregulation in the markets spawns new
competitors.
(v) When switching costs are low so that the buyers can play off the supplying
companies against each other to force down process.
(vi) There is a threat of backward integration by the buyer (e.g. by acquiring a
supplier) if satisfactory prices or quality from suppliers cannot be obtained.
VRIO Framework
The VRIO framework, as given by Barney, helps an organisation to evaluate its competencies with the help of
Copyright@DEEPAKCLASSES DEEPAK CLASESS – Youtube Channel
the following questions:
◉ Value: It questions whether the firm’s competencies provide customer value and competitive
advantage or not. It should be mentioned that threshold competencies only help a firm to exist in
business and do not provide any competitive advantage. Competitive advantage comes from core
competencies.
◉ Rareness: It questions the extent to which the competencies of the firm are rare. In other words,
whether the competitors or the rivals possess the same competencies or not. The rarity component
can help organisations to be competitively superior compared to its rivals.
◉ Imitability: One of the factors on which the durability of competitive advantage depends is the barriers
to imitation. The greater are the barriers the more durable will be the firm’s competitive advantage.
Tangible resources are easy to imitate whereas intangible resources such as reputation, capabilities,
marketing strategies and technologies are difficult to imitate.
◉ Organisation: It refers to the level at which a firm is organised to utilise its resources. A firm where
employees are able to take more risks, bring innovation and get rewarded is in a better situation in
terms of utilisation of firm’s resources. Having an organised structure is fundamental to the optimal
utilisation of resources
Primary activities are directly concerned with the creation or delivery of a product or service. For example, for
a manufacturing business the primary activists are as follows:
◉ Inbound logistics are activities concerned with receiving; storing and distributing inputs to the product
or service including materials handling, stock control, transport, etc.
◉ Operations transform these inputs into the final product or service. Operations include machining,
packaging, assembly, testing, etc.
◉ Outbound logistics collect, store and distribute the product to customers, for example warehousing,
materials handling, distribution, etc.
◉ Marketing and sales provide the means whereby consumers/users are made aware of the product or
service and are able to purchase it. This includes sales administration, advertising and selling.
◉ Service includes those activities that enhance or maintain the value of product or service, such as
installation, repair, training and spares.
◉ Technology development: All value activities have a ‘technology’, even if it is just know-how.
Technologies may be concerned directly with a product or with processes or with a particular
resource.
◉ Human resource management: This transcends all primary activities. It is concerned with those
activities involved in recruiting, managing, training, developing and rewarding people within the
organisation.
◉ Infrastructure: The formal systems of planning, finance, quality control, information management, and
the structures and routines that are part of an organisation’s culture.
In the value chain process the value can be added early in the value chain, i.e. upstream and later in the value
chain, i.e. downstream.
SWOTC Analysis
Copyright@DEEPAKCLASSES DEEPAK CLASESS – Youtube Channel
S = Strength
W = Weaknesses
O = Opportunities
T/C = Threats or Challenges
Corporate Weaknesses:
Similar to Corporate strengths, there may be corporate weaknesses too. These may be
enumerated as under:
• Under-utilisation of capacity due to economic slump
• High debt burden in the capital structure
• Poor product-mix
• Lack of managerial strengths
• Technology gap
• Demand gap
• Poor infrastructures
• Raw materials source at a distance
• Lack of latest information technology
• Competition war
Both corporate strength and corporate weaknesses are examined and reviewed
together in connection with corporate mission and objectives. A balanced and
appropriate mix from both strengths and weaknesses is made in order to
formulate a good corporate plan, which can be achieved and fulfilled during it’s
entire plan period
Now we outline the ‘opportunities’ and ‘threats’
Opportunities:
• Seasonal/climatical demand of products
• Global markets for the company’s products/services (Export opportunities)
• To explore the markets in the undeveloped/under-developed/developing
states/places
• To avail of the incentives/concessions declared by Central and State
Governments
• Diversifications opportunities
• Mergers/acquisition opportunities
Copyright@DEEPAKCLASSES DEEPAK CLASESS – Youtube Channel
• Good home market available due to boost in the economy
• Liberalised policies of the Government both at Centre as well as State level for
the individual production and industrial developments
Similar to opportunities, there may be threats too prevailing from time
to time, which must be examined and necessary action taken to be free
from these or to solve these prudently so that loss to the organisation
may be minimum. The probable threats, which may arise or be faced by
the organisation, are listed out as under
BCG MATRICES
The Boston Consulting Group (BCG)’s matrix analyses ‘products and businesses by market share and market
growth.’
The Boston Consulting Group (BCG) growth-share matrix is a planning tool that uses graphical representations
of a company’s products and services in an effort to help the company decide what it should keep, sell, or
invest more in.
The matrix plots a company’s offerings in a four-square matrix, with the y-axis representing the rate of market
growth and the x-axis representing market share. It was introduced by the Boston Consulting Group in 1970. 1
The BCG growth-share matrix breaks down products into four categories, known as "dogs," "cash cows,"
"stars," and “question marks.” Each category quadrant has its own set of unique characteristics
Understanding the Boston Consulting Group (BCG) Matrix
The horizontal axis of the BCG Matrix represents the amount of market share of a product and its strength in
the particular market. By using relative market share, it helps measure a company’s competitiveness.
1. Question marks: Products with high market growth but a low market share.
2. Stars: Products with high market growth and a high market share.
3. Dogs: Products with low market growth and a low market share.
4. Cash cows: Products with low market growth but a high market share.
The vertical axis of the BCG Matrix represents the growth rate of a product and its potential to grow in a
particular market.
1. Cash cows
Cash cows have a high market share but a low growth rate. Which actually means they don’t cost much but
promise high returns. A good example of a cash cow is Google’s online advertising business. They have a high
market share in a saturated market and don’t need to spend a lot to get high returns from the business.
Every business portfolio wants to maximize cash cows and is the eventual aim of all business units.
2. Stars
Stars have a high market share and a high growth rate. They can generate some profit, however, growth is at
the expense of money and these are cash consuming. The hope is that eventually the stars will be
transformed into cash cows.
Android business for google is a Star. They have a very high market share in a high growth market but it is
consuming money.
3. Question marks
Question marks are the ‘problem child’, they have high growth potential but a low market share. With a lot of
(financial) support and strategic, they can be turned into stars.
Google plus business for Google in Social Media space was a question mark. However, it is another matter
they couldn’t turn it into a Star and eventually had to shelve it. this, however, makes the question marks a
difficult decision to make. It can go either way, it can move to be a Star or it can move into a Dog.
4. Dogs
These are business units with a low share in a saturated market. Dogs should be held on to only if they have a
value other than a financial one (e.g. a vanity project or favor for a friend).
Online blogging platform Blogger for Google can be an example of Dogs. It is operating in a, now obsolete
user-generated blogging space but still has a much lower market share. Whether Google is going to liquidate
the business is to be seen.
The BCG Matrix produces a framework for allocating resources among different business units and makes it
possible to compare many business units at a glance. But BCG Matrix is not free from limitations, such as-
1. BCG matrix classifies businesses as low and high, but generally businesses can be medium also. Thus,
the true nature of business may not be reflected.
2. Market is not clearly defined in this model.
3. High market share does not always leads to high profits. There are high costs also involved with high
market share.

4. Growth rate and relative market share are not the only indicators of profitability. This model ignores
and overlooks other indicators of profitability.
5. At times, dogs may help other businesses in gaining competitive advantage. They can earn even more
than cash cows sometimes.
6. This four-celled approach is considered as to be too simplistic.
Select strategies
Managers select strategies that build on the organisation’s strengths and correct its weaknesses in order to
take advantage of external opportunities and counter external threats. In order to select the right strategies
managers compare and contrast the various alternative possible strategies against each other and then
identify the set of strategies that will create and sustain a competitive advantage. It is very important for the
strategic managers to keep in mind that the strategies selected should be consistent with the mission and
major goals of the organisation. They should be congruent and constitute a viable business model.
The strategy planning process is a continuous process and the feedback loop indicates that strategic planning
never ends. In order to determine the extent to which strategic goals and objectives are actually being
achieved, and to what degree competitive advantage is being created and sustained execution of the strategy
must be monitored. This information and knowledge is returned to the corporate level through feedback
loops, and becomes the input for the next round of strategy formulation and implementation. Top managers
can then decide whether to reaffirm the existing business model and the existing strategies and goals, or
suggest changes for the future.
◉ Economic Factors
These factors are determinants of an economy’s performance that directly impacts a
company and have resonating long term effects. For example, a rise in the inflation rate
of any economy would affect the way companies price their products and services.
Adding to that, it would affect the purchasing power of a consumer and change
demand/supply models for that economy. Economic factors include inflation rate,
interest rates, foreign exchange rates, economic growth patterns, etc. It also accounts for
the FDI (foreign direct investment) depending on certain specific industries who’re
undergoing this analysis.
◉ Socio-cultural factors
These factors scrutinize the social environment of the market, and gauge determinants like
cultural trends, demographics, population analytics, etc. An example of this can be buying
trends for Western countries like the US where there is high demand during the Holiday
season.
◉ Technological factors
These factors pertain to innovations in technology that may affect the operations of the
industry and the market favorably or unfavorably. This refers to automation, research and
development, and the amount of technological awareness that a market possesses.
◉ Environmental factors
Copyright@DEEPAKCLASSES DEEPAK CLASESS – Youtube Channel
They include protection laws, waste disposal, energy consumption, weather,
climate, climate change and associated factors like water shortages. These factors
can directly impact industries such as insurance, farming, energy production, and
tourism. They may have an indirect but substantial effect on other industries such
as transportation and utilities.
◉ Legal
These factors have both external and internal sides. There are certain laws that affect the
business environment in a certain country while there are certain policies that companies
maintain for themselves. Legal analysis takes into account both of these angles and then
charts out the strategies in light of these legislations. For example, consumer laws, safety
standards, labor laws, etc.
Explain the concept of PESTEL Framework?
Threat of entry will depend on the extent to which there are barriers to entry. Barriers
to entry are factors that need to be overcome by new entrants if they are to compete
successfully. These should be seen as providing delays to entry and not as permanent
barriers. The typical barriers are:
• Economies of Scale
Economies of scale arise when unit costs fall as a firm expands its output. Sources
of scale economies include cost reductions gained through mass producing a
standardised commodity, discounts on bulk purchases of raw material inputs
and component parts, the advantages gained by spreading fixed production
costs over a large production volume and the cost savings associated with
spreading marketing and advertising costs over a large volume of output. If
theses cost advantages are significant then a new company that enters the
industry and produces on a small scale suffers a significant cost disadvantage
relative to established companies.
• Brand Loyalty
Brand loyalty exists when consumers have a preference for the products of
established companies. A company can create a brand loyalty through
continuous advertising of its brand-name products and company name, patent
protection of products, product innovation achieved through company
research and development programs, an emphasis on high product quality and
good after sales service.
• Government Regulation
Legal restraints on competition vary from patent protection, to regulation of
markets, through to direct government action. Of course, managers in the
hitherto protected environments might face the pressures of competition for
the first time if governments remove such protection. Historically, government
regulation has constituted a major barrier into many industries
Corporate Weaknesses:
Similar to Corporate strengths, there may be corporate weaknesses too. These may be
enumerated as under:
• Under-utilisation of capacity due to economic slump
• High debt burden in the capital structure
• Poor product-mix
• Lack of managerial strengths
• Technology gap
• Demand gap
• Poor infrastructures
• Raw materials source at a distance
• Lack of latest information technology
• Competition war
Both corporate strength and corporate weaknesses are examined and reviewed
together in connection with corporate mission and objectives. A balanced and
appropriate mix from both strengths and weaknesses is made in order to formulate
a good corporate plan, which can be achieved and fulfilled during it’s entire plan
period
Now we outline the ‘opportunities’ and ‘threats’
Opportunities:
• Seasonal/climatical demand of products
• Global markets for the company’s products/services (Export opportunities)
• To explore the markets in the undeveloped/under-developed/developing
states/places
• To avail of the incentives/concessions declared by Central and State
Governments
• Diversifications opportunities
• Mergers/acquisition opportunities
• Good home market available due to boost in the economy
• Liberalised policies of the Government both at Centre as well as State level for
the individual production and industrial developments
Similar to opportunities, there may be threats too prevailing from time to
time, which must be examined and necessary action taken to be free from
these or to solve these prudently so that loss to the organisation may be
minimum. The probable threats, which may arise or be faced by the
organisation, are listed out as under
Threats & Challenges:
• Globalisation
• Competition
• Price cutting war
• Free imports
• Political instability
• Quality thrusts
• High and adverse debt equity ratio
• Increase in financing cost
• Economic slow down due to international recession impact
Explain the concept of BCG Matrices?
The Boston Consulting Group (BCG)’s matrix analyses ‘products and businesses by market share and market
growth.’
• The Boston Consulting Group (BCG) growth-share matrix is a planning tool that uses
graphical representations of a company’s products and services in an effort to help the
company decide what it should keep, sell, or invest more in.
• The matrix plots a company’s offerings in a four-square matrix, with the y-axis
representing the rate of market growth and the x-axis representing market share. It was
introduced by the Boston Consulting Group in 1970.1
• The BCG growth-share matrix breaks down products into four categories, known as
"dogs," "cash cows," "stars," and “question marks.” Each category quadrant has its own
set of unique characteristics
• The horizontal axis of the BCG Matrix represents the amount of market share of a
product and its strength in the particular market. By using relative market share, it helps
measure a company’s competitiveness.
• The vertical axis of the BCG Matrix represents the growth rate of a product and its
potential to grow in a particular market.

◉ Competitive strategy, industry position and geographic location: CSFs also arise from
the above factors for e.g. the large pool of English- speaking manpower makes India an
attractive location for outsourcing the BPO needs of American and British firms.
◉ Environmental Factors: CSFs may also arise out of general/business environment of a
firm, like the deregulation of Indian industry. With the deregulation of
telecommunication industry, many private companies had opportunities of growth.
Temporal factors: Certain short-term organisational developments like sudden loss of critical
manpower (like the charismatic CEO) or break-up of the family owned business, may
necessitate CSFs like ‘appointment of a new CEO’ or ‘rebuilding the company image’.
Temporarily such CSFs would remain CSFs till the time they are achieved. In the process of
developing alternatives, it may be useful to narrow down the range of options by identifying
the more promising alternatives, in the light of the Critical Success Factor (CSFs). The options
relevant to those factors may be analyzed along with a forecast of their outcome
Module 10 Formulation And Implementation of
Strategy
This Module Includes
PRODUCTION STRATEGY
MARKETING
STRATEGY MARKET: Market is an arrangement that provides an opportunity of exchange of
goods and services, for money or money’s worth. It is the means to settle the terms of
exchange.
Definition of marketing “is getting the right goods and services to the right people at the
rightplace, at the right time, at the right price, with right communication and promotion.”
Marketing Functions:
Marketing involves eight important functions:
1. Buying,
2. Selling,
3. Storage,
4. Transportation,
5. Financing,
6. Standardisation,
7. Grading and
8. Risk-Taking.
Marketing Plan:
1. Marketing plan is a written document that specifies in detail the firms marketing objectives
and how marketing management will use the controllable marketing toolssuch as product
design, channels, promotion and pricing to achieve these objectives
2. Marketing strategy means finding attractive opportunities and developing profitableways
to capture the market.
a) target market,
b) customer needs,
c) coordinated marketing and
d) profitability
Selling Concept
The selling concept takes an inside-out perspective. The four pillars of selling concept
a) Factory
b) Products
c) Selling and Promoting
d) Profits through Sales volume
It starts with the factory, focuses on the company’s existing products, and calls for heavy
selling and promoting to produce profitable sales. The marketing concept takes an
outside-inperspective. It starts with a well-defined market, focuses on customer needs,
co-ordinates allthe activities that will affect customers and produces profit through
customer satisfaction
Social Marketing:
Societal marketing concept calls for a customer orientation backed by integrated
marketingaimed at generating customer satisfaction and long-run consumer welfare as
the key to attaining long-run profitable volume.
Marketing Management:
Marketing management is the crucial and creative task of delivering consumer satisfaction
andthereby earning, profits through consumer demand.
Marketing Strategies:
a) Marketing strategy is a process that can allow an organisation to concentrate its
limitedresources on the greatest opportunities to increase sales and achieve a
sustainable competitive advantage.
b) A marketing strategy should be centered around the key concept that
customersatisfaction is the main goal.
c) Markets can be described and defined by their nature of competition.
d) The marketer’s first task is to select a promising market arid identify its needs
andbuying patterns, after which he formulates strategies for each controllable
factor (product, distribution, promotion and pricing).
e) In formulating and implementing overall marketing strategy, management concerns
itself with identifying opportunities to serve target markets profitably and serving
themso effectively that it is difficult for competitors to take business away on a
profitable basis.
f) The importance of formalized overall marketing strategies (i.e., deliberately
plannedcompetitive postures) varies with the competitive setting. There are four
types of competitive settings
1. No direct competition 2. Pure competition 3. Monopolistic
competition 4.Oligopolistic competition
g) Achieving goals -- operational ideas for changes that will alter the perception of the
storefront by the public to conform to the strategic goals
Manpower Strategy
1. The concept of Human Resource Development (HRD) has evolved over time with
therecognition of people employed in organisations as a resource.
2. Strategic management of human resources includes assessing staffing needs in the
lightof strategies formulated and developing a staffing plan for implementation of
strategy.
3. The compensation and incentive payments necessary to motivate technically
skilled employees and managers also need to be kept in view in connection with
the staffingplan.
4. The basic policy in that respect is to be that of linking corporate earnings with
individualbenefits
5. The following aspects of human resource strategy are required to be focused for
thepurpose:
a) Job analysis and human resource planning before selection and
recruitment ofmanpower,
b) Recruitment and selection of staff with required skill and abilities with the
processbeing consistent with the objectives,
c) Human resource development by way of training and development
programmes,performance appraisal, appropriate compensation package and
incentive schemes to secure motivation.
Features human resource strategy
1. Orientation of the members. HRM strategy has to ensure that individuals
employedin the organisation have necessary orientation so that the mission and
objectives of the organisation are internalised by the members and they have a
sense of identification with the values and culture of the organisation.
2. Facilitation of organisational changes as and when called for. The practices and
procedures are required to be in conformity with the changing internal and
externalconditions. This is a vital role of HR strategy management.
3. Coping with diversity of workforce. Modern organisations with highly complex
nature of jobs and processes generally have a highly diversified workforce
differentiated in terms of age, sex, religion, professional and technical skills and
educational background.To maintain a balanced workforce with harmonious
relations and providing equitable incentives and rewards are aspects of HRM
functions which can sustain an effective workforce. This is a responsibility of HR
strategy managers.
4. Maintaining competent and committed workforce in a competitive environment.
The intensity of market competition for enterprises has been growing fast with
globalisationand liberaliation of economic policies. There are competitive strategies
of low cost production and differentiation of products which may enable companies
to secure a competitive edge. HRM has the responsibility of managing workforce so
as to make it competent in ability as well as committed to organisational success.
5. Development of core competency. An enterprise succeeds in achieving its strategic
objectives mainly on the basis of capabilities in the technical, marketing or human
skillsin areas of crucial importance. These are known as core competencies of the
organisation which are unique internal strengths not possessed by competitors.
HRM isrequired to undertake building up of core competency by the organisation as
to securedynamic leadership in the product market.
6. Empowered workforce as an active resource. HR strategy is best managed when
the members of an organisation are individually in control of their work and are able
to realise their potentials with empowerment to take relevant decisions on their
own. Thisis likely to secure enduring performance based achievements.
7. Appropriate work culture and ethical norms. No organisation can get the best
contribution from its members unless individuals develop a liking for challenging
jobs and follow the ethical norms of the organisation functionally. This may require
redesigning of jobs and work processes as well as developing trust and confidence
among individuals and work groups, as also emphasising intrinsic motivation for
improving performance. HRM encompasses creation of an appropriate work culture
onthe above lines.
Chapter -2 STRUCTURING OF ORGANIZATION FOR IMPLEMENTATIONOF STRATEGY
Introduction
Strategy implementation is a critical issue. Strategies remain useless unless they are
effectivelyimplemented. Strategy implementation requires a suitable organizational
structure to translate the strategies into concrete action plans.
Strategic Implementation
Strategy is dependent on many variables – Internal as well as external. All factors
areinterrelated.
The Mckinsey Company, a well known management consultancy firm in the United States,
towards the end of 1970s was asked to find a solution to this knotty issue. A strategy is
usuallysuccessful when the other S’s in the 7-S framework fit into or support the strategy.
•Structure: The organisation chart and associated information that shows who
reports towhom and how tasks are both divided and integrated.
•Systems: The flow of activities involved in the daily operation of a business, including its
coreprocesses and its support systems.
•Style: How managers collectively spend their time and attention and how they use
symbolicbehaviour. How management acts is more important than what management
says.
•Shared Values: Commonly held beliefs, mindsets and assumptions that shape how
anorganisation behaves— its corporate culture.
Organizational Structure
The successful implementation of Strategy requires an effective organization structure.
Organizational structure means the framework in which the organization defines how
tasksare divided, resources are deployed and departments are co-ordinated. There are
several types of organizational structure:
Functional structure:
The functional structure is characterized by the simultaneous combination of similar
activities and the separation of dissimilar activities on the basis of function. All Cost
Accountants are located in the Cost Accounting Department, and the HOD of Cost
Accounting is responsible forall cost related activities. The same is true in marketing,
research and development, and manufacturing. The functional organization form is one of
the most common organizational structures found in firms pursuing strategy of
concentration or very high relatedness. A functional structure is most appropriate when
the organization is small to medium size and relatively stable.
Geographic structure:
Another basic form structural grouping is geographic structure, in which activities and
personnel are grouped by specific geographic locations. Each geographic unit includes all
functions required to produce and market products in that region. Organization
according togeographic areas or territories is rather common structural form for large-
scale enterprise whose strategies need to be tailored to fit the particular needs and
features of different.
Matrix structure:
Another way to achieve focus on multiple outcomes is with the matrix structure. The
matrix structure creates a dual chain of command; two lines of budget authority and two
sources ofperformance and reward. The key feature of the matrix is that product (or
business) and functional lines of authority are overlaid to form a matrix or grid, between
the product manager and functional manager.
SBU Structure Big organisation like Unilever, etc have many SBUs for their
differentcategories of products like Cosmetics, Food products and Beverages, etc,
and each is managed through separate unit head.
Advantages:
businessesDisadvantages:
• May provide inconsistent approach to tackle customers, etc, because
eachunit may work in it’s own way to handle situations
• High cost approach
Matrix Organisation
Structure:
Advantages:
• Has a manager who has responsibility for strategic planning and profit
performance, and who has control of profit-influencing factors.
Chapter-4 BUSINESS PROCESS RE-ENGINEERING
Business process reengineering is an approach used to improve organizational
performance by increasing the efficiency and effectiveness of processes that exist
across the organization. In addition to the redesigning of business processes, it
also involves the redesigning of associated systems and organizational structures.
• Strategy
• Organization
• Process
• Technology
• Culture
BPR includes three phases; analysis phase, design phase, and implementation
phase. It is also referred to as business process redesign, business process change
management, and business transformation.
goalsstep 2: Establish a
Matrix structure:
Another way to achieve focus on multiple outcomes is with the matrix structure. The
matrix structure creates a dual chain of command; two lines of budget authority and
two sources ofperformance and reward. The key feature of the matrix is that product
(or business) and functional lines of authority are overlaid to form a matrix or grid,
between the product manager and functional manager.
Multidivisional Structure
A multidivisional structure is built up of separate divisions on the basis of products, services
or geographical areas. Divisionalisation often comes about as an attempt to overcome the
problems that functional structures have in dealing with the diversity mentioned above.
Each division can respond to the specific requirements of its product/ market strategy,
using its own set of functional departments.
The transnational structure
The transnational structure seeks to obtain the best from the two extreme international
strategies, the multi domestic strategy and the global strategy. A global strategy would
typically be supported by global product divisions; a multi domestic strategy would be
supported by local subsidiaries with a great deal of design, manufacturing and marketing
autonomy for all products. The transnational structure, however, attempts to achieve both
high local responsiveness and high global coordination. The transnational is like a matrix
but has two specific features: first, it responds specifically to the challenge of
internationalisation; second, it tends to have more fixed responsibilities within its
crosscutting dimensions.
Advantages:
• Promotes accountability since units’ heads are responsible for individual SBU
profitability
• Career development opportunities are further higher in this structure
• Allow better control of categories of products manufacturing, marketing and
distributions
• Helps to expand in different related and unrelated businesses
Disadvantages:
◉ Create direction
One of the reasons for lack of goal congruence is the absence of direction related to
employees’ behaviour. Performance management and goals facilitate efficient
communication about what managers want their subordinates to focus on. It needs
no mention that providing clear information and direction, employees can better
understand what is expected from them, how to perform adequately, and how to
contribute effectively to the achievement of the organisational goals. There is a
need to increase the employees understanding of the strategic objectives as well as
the organisation’s value drivers.
◉ Motivation
The problem of motivation can exist even though employees have knowledge about
how to perform adequately because employees can act in their own self interest
instead of in the organisation’s best interest. The employees can make their own
performance report better by allocating resources without befitting the
organisation as a whole. One of the strongest reasons for demotivation among
employees and managers is dislike for the work allocated. The reason for motivation
varies among employees. While some employees feel motivated for some
recognition and appraisals others may feel motivated because of commitment and
responsibility without any required pay off. The more motivated the employees of
the organisation the better will be the goal congruence.
◉ Incentives
In order to increase the likelihood of employees working to achieve their individual
goals, organisation’s aim to influence motivation by providing incentives. Research
suggests that individuals tend to perform better when they are rewarded. Rewards
and compensations should create goal congruence between individual goals and
organisational goals by stimulating individuals to perform by providing incentives, as
rewards are related to increased effort.
◉ Connection
It is very important to create a connection between goals, performance measures and
incentives. In order to align the employees’ self interest and overall organisational
objectives it is necessary to relate incentives with performance. By linking incentives
to certain goals, individuals tend to pay more attention to what is important.
➢ Digital strategy, on the other hand, focuses on technology, not culture. Digital
strategy is most relevant to changes in business models, and uses technology to
create the capabilities a company needs to become a digital business. Setting down a
strategy is a key component of the transformation process, and ensures that
technology is being implemented in a way that supports the business objectives.
➢ In today’s organization, there are many ideas of what constitutes a digital strategy. A
marketing executive will see a digital strategy as social media and web channels. An
IT person would see a digital strategy as cloud. An operations executive will see it as
data analytics. An R&D executive would see it as online products. A financial person
will see it as online revenue channels.
◉ Attack vs. Defend- McKinsey & Company emphasizes that companies would do well
to categorize their potential threats and opportunities in digital business, then
compare these against their own purpose. This clarifies whether a proactive or
defensive stance needs to guide new initiatives.
◉ A ‘structured data’ is any data that can be stored, accessed and processed in
the form of fixed format. A lot of success has been achieved over a period of
time in developing techniques for working with such kind of data (where the
format is well known in advance) and also deriving value out of it.
◉ A semi-structured data can contain both the forms of data. Example of semi-
structured data is a data represented in an XML file.
◉ Variety – Variety refers to heterogeneous sources and the nature of data, both
structured, unstructured and semi structured. During earlier days, spreadsheets and
databases were the only sources of data considered by most of the applications
however, in recent period data can be in the form of emails, photos, videos,
monitoring devices, PDFs, audio, etc.. These data also need to be analysed.
◉ Velocity – The term ‘velocity’ refers to the speed of generation of data and
processing of data to be responsive to the needs of the customers. Big Data velocity
deals with the speed at which data flows in from sources like business processes,
application logs, networks, and social media sites, sensors, mobile devices, etc. The
flow of data is massive and continuous.
◉ Variability – This refers to the inconsistency which can be shown by the data at
times, thus hampering the process of being able to handle and manage the data
effectively.
◉ These services are divided into three main categories or types of cloud computing:
infrastructure as a service (IaaS), platform as a service (PaaS) and software as a
service (SaaS).
a) IaaS providers, such as Amazon Web Services (AWS), supply a virtual server
instance and storage, as well as application programming interfaces (APIs) that
let users migrate workloads to a virtual machine (VM). Users have an allocated
storage capacity and can start, stop, access and configure the VM and storage
as desired.
◉ Data and workload mobility: Cloud computing allows users to access data from
anywhere with any device with just an internet connection. That means users don’t
have to carry around USB drives, an external hard drive or multiple CDs to access
their data. Users can access corporate data through smart phones and other mobile
devices, enabling remote employees to stay up to date with co-workers and
customers. End users can easily process, store, retrieve and recover resources in the
cloud. In addition, cloud vendors provide all the upgrades and updates automatically,
saving time and effort.
◉ Business continuity and disaster recovery (BCDR): The biggest worry for
organisations in the present digital landscape is data loss. Storing data in the cloud
guarantees that users can always access their data even if their devices, e.g., laptops
or smart phones, are inoperable. With cloud-based services, organisations can
quickly recover their data in the event of emergencies, such as natural disasters or
power outages. This benefits BCDR and helps ensure that workloads and data are
available even if the business suffers damage or disruption.
◉ Cost unpredictability: The concept Pay-as-you-go subscription plans for cloud use,
along with scaling resources to accommodate fluctuating workload demands, can
make it tough to define and predict final costs.
◉ Compliance with industry laws: When transferring data from on-premises local
storage into cloud storage, it can be difficult to manage compliance with industry
regulations through a third party. Management of multiple clouds: Every cloud is
different, so multi-cloud deployments can disjoint efforts to address more general
cloud computing challenges.
◉ Cloud performance: Network and provider outages can interfere with productivity
and disrupt business processes if organisations are not prepared with contingency
plans.
◉ Building a private cloud: Architecting, building and managing private clouds whether
for its own purpose or for a hybrid cloud goal can be a daunting task for IT
departments and staff.
◉ Cloud migration: The process of moving applications and other data to a cloud
infrastructure often causes complications. Migration projects frequently take longer
than anticipated and go over budget.
◉ Vendor lock-in: Switching between cloud providers can cause significant issues. This
includes technical incompatibilities, legal and regulatory limitations and substantial
costs incurred from sizable data migrations.
◉ There are three levels of AI namely; Narrow AI, General AI/human-level and Super AI.
◉ Super AI, the highest level of AI, is reached when AI becomes much smarter than the
best human brains in practically every field.
◉ AI since its output is used as the basis for recommendations, decisions, and feedback
mechanisms with regards to a previously unknown situation.
◉ ML is an approach to creating AI. As most AI systems today are ML-based, the terms
are often used interchangeably-particularly in a business context.
◉ Deep learning is a branch of AI. It mainly deals with neural networks that consist of
many layers, hence the name “deep.” In the last years, deep neural networks have
been the most successful AI approach in many areas.
◉ AI also has the ability to help detection and analysis mechanisms, improve its own
accuracy by continuously learning from the issues detected, and optimize
manufacturing processes by incorporating feedback and adjusting the control
parameters accordingly.
◉ Immutable records No participant can change or tamper with a transaction after it’s
been recorded to the shared ledger. If a transaction record includes an error, a new
transaction must be added to reverse the error, and both transactions are then
visible.
◉ Greater security The increase security in blockchain network arises from the fact that
consensus on data accuracy is required from all network members, and all validated
transactions are immutable because they are recorded permanently. No one, not
even a system administrator, can delete a transaction.
◉ RPA bots are capable of mimicking most human-computer interactions to carry out a
ton of error-free tasks, at high volume and speed.
◉ Robotic process automation tools are best suited for processes with repeatable,
predictable interactions with IT applications.
◉ RPA tools can improve the efficiency of these processes and the effectiveness of
services without fundamental process redesign.
◉ The benefits of RPA solutions not only reduce cost but also include:
◉ Search Engine Optimization (SEO) Marketing Search engine optimization often goes
hand in hand with content marketing. When the customer from the above example is
conducting research for which gym shoes to buy, they will probably click on one of
the first three results that appear on Google. With this in mind, the athletic shoes’
marketing team wants to ensure their article appears in those top results. This is
done by optimizing content for user experience and ensuring the technical elements
are in place to enable search engine crawlers to easily find and index this content
◉ Mobile Marketing Mobile marketing initiatives can include many of the digital
marketing strategies mentioned above, and typically will leverage a combination of
text messages, social media, email, push notifications, and mobile applications. The
importance of mobile marketing is rising, as it is expected that by 2024, the number
of mobile shoppers will rise to approximately 187.5 million users. With the clear
move to mobile, marketers need to think about how they can optimize their current
marketing efforts for mobile to be able to deliver a seamless and user-friendly
experience.
