BBA Management Info Systems Guide
BBA Management Info Systems Guide
A computer information system is a system composed of people and computers that processes or
interprets information. The term is also sometimes used in more restricted senses to refer to only
the software used to run a computerized database or to refer to only a computer system.
Any specific information system aims to support operations, management and decision-making.
An information system is the information and communication technology (ICT) that an
organization uses, and also the way in which people interact with this technology in support of
business processes.
Some authors make a clear distinction between information systems, computer systems, and
business processes. Information systems typically include an ICT component but are not purely
concerned with ICT, focusing instead on the end use of information technology. Information
systems are also different from business processes. Information systems help to control the
performance of business processes.
Alter argues for advantages of viewing an information system as a special type of work system.
A work system is a system in which humans or machines perform processes and activities using
resources to produce specific products or services for customers. An information system is a
work system whose activities are devoted to capturing, transmitting, storing, retrieving,
manipulating and displaying information.
As such, information systems inter-relate with data systems on the one hand and activity systems
on the other. An information system is a form of communication system in which data represent
and are processed as a form of social memory. An information system can also be considered a
semi-formal language which supports human decision making and action.
The computer age introduced a new element to businesses, universities, and a multitude of other
organizations: a set of components called the information system, which deals with collecting
and organizing data and information. An information system is described as having five
components.
1. Computer hardware
This is the physical technology that works with information. Hardware can be as small as a
smartphone that fits in a pocket or as large as a supercomputer that fills a building. Hardware
also includes the peripheral devices that work with computers, such as keyboards, external disk
drives, and routers. With the rise of the Internet of things, in which anything from home
appliances to cars to clothes will be able to receive and transmit data, sensors that interact with
computers are permeating the human environment.
2. Computer software
The hardware needs to know what to do, and that is the role of software. Software can be divided
into two types: system software and application software. The primary piece of system software
is the operating system, such as Windows or iOS, which manages the hardware’s operation.
Application software is designed for specific tasks, such as handling a spreadsheet, creating a
document, or designing a Web page.
3. Telecommunications
This component connects the hardware together to form a network. Connections can be through
wires, such as Ethernet cables or fibre optics, or wireless, such as through Wi-Fi. A network can
be designed to tie together computers in a specific area, such as an office or a school, through a
local area network (LAN). If computers are more dispersed, the network is called a wide area
network (WAN). The Internet itself can be considered a network of networks.
This component is where the “material” that the other components work with resides. A database
is a place where data is collected and from which it can be retrieved by querying it using one or
more specific criteria. A data warehouse contains all of the data in whatever form that an
organization needs. Databases and data warehouses have assumed even greater importance in
information systems with the emergence of “big data,” a term for the truly massive amounts of
data that can be collected and analyzed.
5. Human resources and procedures
The final, and possibly most important, component of information systems is the human element:
the people that are needed to run the system and the procedures they follow so that the
knowledge in the huge databases and data warehouses can be turned into learning that can
interpret what has happened in the past and guide future action.
Information Systems in Business
Business information systems are sets of inter-related procedures using IT infrastructure in a
business enterprise to generate and disseminate desired information.
Such systems are designed to support decision making by the people associated with the
enterprise in the process of attainment of its objectives.
The business information system gets data and other resources of IT infrastructure as input from
the environment and process them to satisfy the information needs of different entities associated
with the business enterprise.
There are systems of control over the use of IT resources and the feedback system offers useful
clues for increasing the benefits of information systems to business. The business information
systems are sub-systems of business system and by themselves serve the function of feedback
and control in business system.
1. The business information systems are subject to the dynamics of business environment
and need to be flexible enough to absorb the inevitable changes in the information needs
of business. They have to be efficient to satisfy the demanding and ‘hard task masters,’
the business managers. Thus, there is need to balance the conflicting objectives in the
process of designing business information systems.
2. Business information systems need to be proactive. They should anticipate changes in
information needs of users and accordingly adapt themselves to suit their needs. This has
become important because of the fact that the managers get involved in the routine
activities to the extent that the decision making becomes a matter of imitating what
competitors are doing or planning to do, rather than making an informed choice.
3. The purpose of business information system is to cater to the information needs for
decision making in business.
4. The business information systems have to be designed keeping in view the availability of
financial and human resources to the business enterprise.
5. The cost effectiveness is a matter of prime concern in the development and maintenance
of business information systems. Economic justification for investment in IT
infrastructure for business information systems is a pre condition for its existence and
sustenance.
Information systems can be described by four of their key components which are:
1. Decisions
2. Transactions and processing
3. Information and its flow
4. Individuals or functions involved.
It is difficult to observe the decision process through we can see and review the results of a
decision. Transactions are usually more visible, though many current systems use computer
programs, which are not easy to understand, to process transactions. In principle, an observer can
see information and its flows. Individuals can be observed too, but it is not always easy to figure
out the information processing functions they perform.
Influence of Information Systems in
Transforming Businesses
Information systems have transformed the way businesses operate and compete in the modern
era. The integration of technology into various business functions has allowed companies to
streamline their operations, improve their decision-making processes, and enhance their overall
efficiency.
One of the most significant impacts of information systems on businesses is the ability to provide
managers with real-time data that can be used to make informed decisions. For example, with the
help of a data analytics system, a retailer can track sales, customer behavior, and inventory levels
in real-time. This information can be used to make decisions regarding pricing, inventory
management, and marketing strategies. This helps businesses to respond to changes in the market
quickly and make informed decisions.
Increased Efficiency
Information systems can automate routine tasks and improve business processes, which reduces
the time and resources required to complete them. For example, an online booking system can
streamline the booking process for a hotel, eliminating the need for manual booking processes.
Similarly, inventory management systems can automate the ordering process, reducing the time
and resources required to manage inventory.
Information systems can be used to collect and analyze customer data, allowing businesses to
create personalized experiences that cater to the individual needs of their customers. For
example, an online retailer can use customer data to provide personalized product
recommendations, customized promotions, and more. This improves the customer experience
and enhances customer loyalty.
Information systems can be used to manage the supply chain more efficiently. This includes
managing inventory, tracking shipments, and ensuring timely delivery of goods. This leads to
better coordination between suppliers, manufacturers, and retailers, resulting in a more efficient
supply chain that reduces costs and increases productivity.
Information systems can help businesses expand their reach and access new markets. For
example, a business can use e-commerce platforms to sell products and services to customers
around the world, regardless of physical location. This provides businesses with access to new
markets, customers, and revenue streams.
Global E-Businesses and Collaborations
Global e-businesses and collaborations refer to the integration of electronic technologies into the
business processes of companies operating on a global scale. This integration enables companies
to expand their operations beyond their physical boundaries, connect with customers and
partners from different parts of the world, and collaborate with other businesses to create value.
Global e-businesses and collaborations have revolutionized the way businesses operate. With the
help of technology, businesses can expand their reach, access new markets, optimize their supply
chain management systems, collaborate with other businesses, and reduce costs. As technology
continues to evolve, businesses must continue to adapt to remain competitive in the global
marketplace.
E-commerce
E-commerce refers to the buying and selling of goods and services over the internet. This has
enabled businesses to expand their reach and sell their products and services to customers from
all over the world. E-commerce has also enabled businesses to operate 24/7, allowing customers
to purchase products at any time. With the help of digital marketing, businesses can target
specific audiences, resulting in more efficient and effective marketing campaigns.
Digital Payments
Digital payments have revolutionized the way businesses operate. With the help of digital
payment platforms, businesses can securely and quickly send and receive payments from
customers and partners from all over the world. This has made international transactions more
accessible and efficient, reducing the time and cost required to complete them.
Global e-businesses have enabled businesses to optimize their supply chain management systems
by automating the processes involved in sourcing, production, and distribution. With the help of
technology, businesses can track inventory levels, monitor production processes, and manage
logistics in real-time, resulting in a more efficient supply chain.
Collaborations
Collaborations between businesses have become easier with the help of digital technologies.
Companies can collaborate with other businesses from different parts of the world, allowing
them to access new markets and expand their operations. For example, a business can collaborate
with a supplier from a different country to reduce costs or work with a partner to create new
products or services.
Cloud Computing
Cloud computing has enabled businesses to store and process large amounts of data without the
need for physical servers. This has reduced the cost of data storage and processing, making it
more accessible to businesses of all sizes. Cloud computing has also enabled businesses to access
data from anywhere in the world, making collaboration and remote work easier.
Global e-businesses and collaborations are of great importance to businesses operating in the
modern era. The integration of electronic technologies into business processes has enabled
businesses to expand their operations beyond their physical boundaries, connect with customers
and partners from different parts of the world, and collaborate with other businesses to create
value.
Expanded Reach
Global e-businesses have enabled businesses to expand their reach beyond their local markets.
With the help of e-commerce platforms, businesses can sell their products and services to
customers from all over the world, regardless of physical location. This has enabled businesses to
access new markets and increase their customer base, resulting in increased revenue and
profitability.
Reduced Costs
Global e-businesses and collaborations have enabled businesses to reduce costs associated with
traditional business processes. For example, businesses can reduce the cost of storage and
processing data by using cloud computing. Similarly, businesses can reduce the cost of
manufacturing by collaborating with suppliers from different parts of the world.
Improved Efficiency
Global e-businesses and collaborations have enabled businesses to improve their efficiency by
automating routine tasks and optimizing business processes. With the help of technology,
businesses can track inventory levels, monitor production processes, and manage logistics in
real-time, resulting in a more efficient supply chain. This has reduced the time and resources
required to complete business processes, resulting in increased productivity.
Information systems are used to automate business processes, reducing the time and effort
required to complete routine tasks. For example, an enterprise resource planning (ERP) system
can integrate business functions such as accounting, inventory management, and human
resources management, resulting in improved efficiency and productivity.
Information systems can provide organizations with a competitive advantage by enabling them to
differentiate their products or services from those of their competitors. For example, an
organization can use customer relationship management (CRM) systems to provide personalized
customer experiences that differentiate their products or services.
Facilitating Collaboration
Information systems can facilitate collaboration among employees, suppliers, and customers,
enabling them to share information and work together on projects. For example, project
management systems can enable teams to work on projects from different locations, resulting in
improved productivity and reduced costs.
Enabling Innovation
Information systems can enable innovation by providing organizations with the tools and
resources necessary to develop new products or services. For example, computer-aided design
(CAD) systems can enable organizations to design and develop new products, while simulation
and modelling tools can help them test and refine their designs.
Achieving the strategic role of information systems requires careful planning, implementation,
and management. Here are some steps to follow:
Define the organization’s business strategy:
The first step in achieving the strategic role of information systems is to define the organization’s
business strategy. This involves identifying the organization’s goals, objectives, and competitive
advantages. The information systems strategy should be aligned with the business strategy.
Once the business strategy has been defined, the next step is to identify the information needs of
the organization. This involves identifying the types of information required, the sources of
information, and the frequency of information needed.
Based on the information needs, the organization should determine the information systems
requirements. This involves identifying the hardware, software, and network infrastructure
required to support the information systems.
The next step is to develop an information systems plan. This plan should outline the objectives,
scope, and budget of the information systems project. It should also include a timeline and a risk
management plan.
After the information systems plan has been developed, the organization should implement the
information systems. This involves installing the hardware and software, configuring the
network, and training the users.
Once the information systems have been implemented, the organization should monitor and
evaluate their performance. This involves measuring the effectiveness of the information systems
in meeting the information needs of the organization. It also involves identifying areas for
improvement.
Finally, the information systems should be aligned with the business strategy. This involves
ensuring that the information systems are meeting the goals and objectives of the organization. It
also involves making adjustments to the information systems as needed to ensure that they
continue to support the business strategy.
Behavioural, Technical and Socio-technical
approaches
Behavioural, technical, and socio-technical approaches are three different perspectives for
understanding and designing information systems. Each approach focuses on different aspects of
information systems and has different strengths and weaknesses.
The behavioural, technical, and socio-technical approaches each have their own strengths and
weaknesses, and may be more or less appropriate depending on the specific context and goals of
the information system being designed. A comprehensive approach that takes into account all
three perspectives can lead to more effective and sustainable information systems.
Behavioural approach:
The behavioural approach focuses on understanding the behaviour of users and how they interact
with information systems. This approach emphasizes the human element of information systems,
including user attitudes, behaviours, and motivations. The behavioural approach uses techniques
such as interviews, surveys, and observations to gather data about users and their interactions
with information systems. The strengths of this approach are that it considers the user experience
and can lead to more user-friendly and effective systems. The weakness is that it may not
consider technical limitations or cost considerations.
Technical approach:
The technical approach focuses on the technical aspects of information systems, including the
hardware, software, and network infrastructure. This approach emphasizes the efficiency,
reliability, and performance of the system. The technical approach uses techniques such as
system analysis and design, programming, and testing to create and implement information
systems. The strengths of this approach are that it produces technically sound and efficient
systems. The weakness is that it may not consider the user experience or socio-technical factors.
Implementing a new software system to automate repetitive tasks and reduce errors.
Introducing new machinery or equipment to improve production processes.
Socio-technical approach:
The socio-technical approach focuses on the interaction between people, technology, and the
organizational context in which they operate. This approach emphasizes the importance of
understanding the social and organizational context in which information systems are used. The
socio-technical approach uses techniques such as participatory design, ethnographic research,
and change management to design and implement information systems that are effective and
sustainable. The strengths of this approach are that it considers both technical and social factors,
leading to systems that are more effective and accepted by users. The weakness is that it may be
more complex and time-consuming than other approaches.
Redesigning work processes to better align with the skills and abilities of employees,
while also utilizing technology to enhance productivity.
Encouraging collaboration and communication among team members to foster a positive
work environment and improve outcomes.
Enhancing Business Processes through
Information Systems
Enhancing business processes through information systems (IS) involves leveraging technology
to improve the efficiency, effectiveness, and quality of organizational processes.
Here are some ways that IS can be used to enhance business processes:
Information Systems can be used to automate routine, repetitive tasks that are prone to errors and
require significant time and effort. For example, an online booking system can automate the
process of making reservations, reducing the need for manual entry and improving accuracy.
Enhancing Decision-making:
Streamlining Operations:
Information Systems can be used to streamline operations and improve the flow of work
processes. For instance, an organization can use an enterprise resource planning (ERP) system
that integrates all of its business processes into a single system, reducing duplication of effort
and improving data accuracy.
There are several approaches to enhancing business processes through information systems (IS).
Here are three common approaches:
BPR involves the radical redesign of business processes to achieve significant improvements in
performance, efficiency, and quality. This approach involves questioning existing assumptions
and rethinking the way work is done, often resulting in the elimination of non-value-adding
activities. IS can be used to automate and streamline redesigned processes, resulting in
significant improvements in performance.
CPI involves the ongoing effort to improve business processes through incremental changes.
This approach involves identifying areas for improvement and implementing small changes that
can be quickly tested and refined. IS can be used to support CPI initiatives by providing real-
time data and analysis tools that enable teams to identify opportunities for improvement and
monitor progress.
Lean Six Sigma is a methodology that combines the principles of lean manufacturing and Six
Sigma to improve quality and reduce waste. This approach involves identifying and eliminating
non-value-adding activities and reducing process variability. IS can be used to support Lean Six
Sigma initiatives by providing real-time data on process performance, enabling teams to identify
opportunities for improvement and monitor progress.
Types of Business Information Systems:
Transaction Processing System (TPS)
A transaction process system (TPS) is an information processing system for business
transactions involving the collection, modification and retrieval of all transaction data.
Characteristics of a TPS include performance, reliability and consistency.
A transaction process system and transaction processing are often contrasted with a batch
process system and batch processing, where many requests are all executed at one time. The
former requires the interaction of a user, whereas batch processing does not require user
involvement. In batch processing the results of each transaction are not immediately available.
Additionally, there is a delay while the many requests are being organized, stored and eventually
executed. In transaction processing there is no delay and the results of each transaction are
immediately available. During the delay time for batch processing, errors can occur. Although
errors can occur in transaction processing, they are infrequent and tolerated, but do not warrant
shutting down the entire system.
To achieve performance, reliability and consistency, data must be readily accessible in a data
warehouse, backup procedures must be in place and the recovery process must be in place to deal
with system failure, human failure, computer viruses, software applications or natural disasters.
There are several features involved in a good transaction processing system. A few of these
critical features are described below.
1. Performance
The concept behind the use of TPS is to efficiently generate timely results for transactions.
Effectiveness is based on the number of transactions they can process at a particular time.
2. Continuous availability
The transaction processing system should be a very stable and reliable system that must not crash
easily. Disruption of TPS in an organization can lead to work disturbance and financial loss.
3. Data integrity
The TPS must maintain the same method for all transactions processed, the system must be
designed to effectively protect data and overcome any hardware/ software issues.
4. Ease of use
The TPS should be user-friendly in order to encourage the use and also decrease errors from
inputting data. It should be structured in such a way that it makes it easy to understand as well as
guarding users against making errors during data-entry.
5. Modular growth
The TPS hardware and software components should be able to be upgraded individually without
requiring a complete overhaul.
6. Controlled processing
Only authorized personnel, staff members, or employees should be able to access the system at a
time.
1. Batch processing
Batch processing is when clusters of transactions are refined simultaneously using a computer
system.
This method, although designed to be efficient for breaking down bulky series of programs, has a
drawback as there is a delay in the transaction result.
2. Real-time Processing
Real-time processing carries out its transactions exclusively; this method ensures a swift reply on
the condition of the transaction result. It is an ideal technique for dealing with singular
transactions.
1. Processing in a batch
Processing batch transactions requires data collection and batch grouping. Data collected are
stored in the form of batches and may be processed anytime. This long-established technique
was used widely in the absence of infotech.
2. Processing in real-time
Recent technology innovations gave rise to real-time processing. RTP ensures instant data
processing with the aim of providing a quick verification of the transaction. It is highly versatile
as it can work effectively as a multi-user interface and can also be accessed anywhere there is an
online network.
Components of Transaction Processing System
Inputs: These are source documents gotten from transactions which serve as inputs into
the computer’s accounting system examples are invoices, and customer orders.
Processing: This requires the breaking down of information provided by the inputs.
Storage: This is saved information in TPS memory, it may be in the form of ledgers.
Output: Any generated record may serve as the output
TPS accumulates data about transactions and also initiates processing that transforms
stored data. Examples include order processing, employee records, and hotel reservation
systems.
Batch transaction process examples include bill generation and check clearances.
Examples of real-time transaction processes are the point of sale terminals (P.O.S) and
microfinance loan systems.
Managing operations with the TPS can be complicated if the company is not big enough
to efficiently use the transaction processing system.
TPS needs both hardware and software components to efficiently manage high data
volume. This capacity makes TPSs susceptible to software security breaches in the form
of the virus and faulty hardware issues such as power outage can disrupt the whole
system.
Effective integration of a TPS in a company operation requires skilled personnel, it also
requires a link with associate company branches to maintain a secure flow of information.
This high requirement can create instability and flux in the company’s daily operations.
Transaction Processing Systems can execute input, output, storage, and processing functions.
This includes the securing of data on the source document, entering of input data in the system
and also validate data.
This includes the production of the report of the transaction via monitor or paper, examples are
exception reports, detail reports, and summary reports.
This entails the transformation of data, it includes calculation, computation, and apt result.
Types of Recovery
A Transaction Processing System (TPS) is an infotech used to accumulate, store, modify and
retrieve data transactions. Transaction processing systems present a unique response to user
requirements, although planning to choose the most appropriate method relies heavily on the
quantity of data and the type of business.

Decision Support Systems, Attributes,
Characteristics, Classification, Types,
Advantages, Disadvantages:
Decision Support system (DSS) is a computerized program used to support determinations,
judgments, and courses of action in an organization or a business. A DSS sifts through and
analyzes massive amounts of data, compiling comprehensive information that can be used to
solve problems and in decision-making.
Typical information used by a DSS includes target or projected revenue, sales figures or past
ones from different time periods, and other inventory- or operations-related data.
A DSS can be used by operations management and planning levels in an organization to compile
information and data and synthesize it into actionable intelligence. This allows the end user to
make more informed decisions at a quicker pace.
The primary purpose of using a DSS is to present information to the customer in a way that is
easy to understand. A DSS system is beneficial because it can be programed to generate many
types of reports, all based on user specifications. A DSS can generate information and output it
graphically, such as a bar chart that represents projected revenue, or as a written report.

Some DSS may lack flexibility to adapt to rapidly changing business environments.
Integration Challenges:
Integrating DSS with existing systems may pose compatibility and integration challenges.
Learning Curve:
Users may face a learning curve when adopting new DSS tools and interfaces.
Maintenance Requirements:
Regular maintenance and updates are necessary to keep DSS effective and up-to-date.
Components of a DSS
To solve a problem the necessary data may come from internal or external database. In an
organization, internal data are generated by a system such as TPS and MIS. External data come
from a variety of sources such as newspapers, online data services, databases (financial,
marketing, human resources).
It stores and accesses models that managers use to make decisions. Such models are used for
designing manufacturing facility, analyzing the financial health of an organization, forecasting
demand of a product or service, etc.
(iii) Support Tools
Support tools like online help; pulls down menus, user interfaces, graphical analysis, error
correction mechanism, facilitates the user interactions with the system.
Classification of DSS
There are several ways to classify DSS. Hoi Apple and Whinstone classifies DSS as follows:
It contains textually represented information that could have a bearing on decision. It allows
documents to be electronically created, revised and viewed as needed.
Database plays a major role here; it contains organized and highly structured data.
It contains information in spread sheets that allows create, view, modify procedural knowledge
and also instructs the system to execute self-contained instructions. The most popular tool is
Excel and Lotus 1-2-3.
Procedures are adopted in rules oriented DSS. Export system is the example.
Types of DSS
It needs comparative analysis and makes use of formula or an algorithm, for example cash flow
analysis, inventory analysis etc.
In this system data is analyzed and the information report is generated. For example, sales
analysis, accounts receivable systems, market analysis etc.
It keeps track of accounting and finance related information, for example, final account, accounts
receivables, accounts payables, etc. that keep track of the major aspects of the business.
Simulation models or optimization models used for decision-making are used infrequently and
creates general guidelines for operation or management.
2. Scenario Simulation:
o Role of DSS:
Allows for the creation and simulation of different decision scenarios.
Models the potential outcomes of various decision options.
o Impact on Decision Making:
Assists decision-makers in understanding the consequences of different choices.
Supports proactive decision-making by exploring potential scenarios.
5. User-Friendly Interfaces:

One example is the clinical decision support system for medical diagnosis. There are four stages
in the evolution of clinical decision support system (CDSS): the primitive version is standalone
and does not support integration; the second generation supports integration with other medical
systems; the third is standard-based, and the fourth is service model-based.
DSS is extensively used in business and management. Executive dashboard and other business
performance software allow faster decision making, identification of negative trends, and better
allocation of business resources. Due to DSS all the information from any organization is
represented in the form of charts, graphs i.e. in a summarized way, which helps the management
to take strategic decision. For example, one of the DSS applications is the management and
development of complex anti-terrorism systems. Other examples include a bank loan officer
verifying the credit of a loan applicant or an engineering firm that has bids on several projects
and wants to know if they can be competitive with their costs.
DSS are also prevalent in forest management where the long planning horizon and the spatial
dimension of planning problems demands specific requirements. All aspects of Forest
management, from log transportation, harvest scheduling to sustainability and ecosystem
protection have been addressed by modern DSSs. In this context the consideration of single or
multiple management objectives related to the provision of goods and services that traded or
non-traded and often subject to resource constraints and decision problems. The Community of
Practice of Forest Management Decision Support Systems provides a large repository on
knowledge about the construction and use of forest Decision Support Systems.
A specific example concerns the Canadian National Railway system, which tests its equipment
on a regular basis using a decision support system. A problem faced by any railroad is worn-out
or defective rails, which can result in hundreds of derailments per year. Under a DSS, the
Canadian National Railway system managed to decrease the incidence of derailments at the same
time other companies were experiencing an increase.
DSS have been used for risk assessment to interpret monitoring data from large engineering
structures such as dams, towers, cathedrals, or masonry buildings. For instance, Mistral is an
expert system to monitor dam safety, developed in the 1990s by Ismes (Italy). It gets data from
an automatic monitoring system and performs a diagnosis of the state of the dam. Its first copy,
installed in 1992 on the Ridracoli Dam (Italy), is still operational 24/7/365. It has been installed
on several dams in Italy and abroad (e.g., Itaipu Dam in Brazil), and on monuments under the
name of Kaleidos. Mistral is a registered trade mark of CESI. GIS have been successfully used
since the ‘90s in conjunction to DSS, to show on a map real-time risk evaluation based on
monitoring data gathered in the area of the Val Pola disaster (Italy).
DSS tends to be aimed at the less well structured, underspecified problem that upper level
managers typically face;
DSS attempts to combine the use of models or analytic techniques with traditional data access
and retrieval functions;
DSS specifically focuses on features which make them easy to use by non-computer-proficient
people in an interactive mode; and
DSS emphasizes flexibility and adaptability to accommodate changes in the environment and the
decision-making approach of the user.
Typically, business planners will build a DSS system according to their needs and use it to
evaluate specific operations, including
A large stock of inventory, where DSS applications can provide guidance on establishing supply
chain movement that works for a business.
A sales process, where DSS software is a “crystal ball” that helps managers theorize how
changes will affect results.
Other specialized processes related to a field or industry.
DSS can come in handy by evaluating stock held in a facility, or any other type of business asset
that can be moved around or otherwise optimized. This is often one way a business can profit
from “itemizing” its assets with DSS.
Decision support technology can also be a tool that analyzes sales data and makes predictions, or
monitors existing patterns. Whether it’s big picture decision support tools, active or passive
solutions, or any other kind of DSS tool, planners often tackle sales numbers using a variety of
decision support resources.
There are other uses for this powerful software option, to make good projections on the future for
a business or to get an overall bird’s-eye view of events that determine a company’s progress.
This can come in handy in difficult situations where a lot of financial projection may be
necessary when determining expenditures and revenues.

Organising the Information Systems function
in Business
Organizing the Information Systems (IS) function within a business is essential for ensuring that
the organization’s technology systems are effective, efficient, and aligned with the company’s
overall objectives. Below are some general steps that can be taken to organize the IS function in
a business:
IS function’s purpose:
The first step is to define the role and objectives of the IS function within the organization. This
should include identifying the key responsibilities and priorities of the IS function, as well as the
expected outcomes and benefits.
Determine the most appropriate organizational structure for the IS function. Depending on the
size and complexity of the organization, the IS function may be centralized or decentralized. In a
centralized structure, the IS function is a separate department reporting to senior management,
while in a decentralized structure, the IS function may be integrated within different business
units.
Determine reporting lines for the IS function. This may include reporting directly to the Chief
Information Officer (CIO) or other senior executives.
Clearly define the roles and responsibilities of each team member within the IS function,
including areas such as technology infrastructure, application development, and user support.
Establish policies and procedures for managing the IS function, including areas such as security,
data management, and software development.
Hire qualified and experienced individuals to fill the various roles within the IS function. Ensure
that team members have the necessary skills and expertise to perform their duties effectively.
Establish metrics:
Define metrics for measuring the performance of the IS function. This may include measures
such as system uptime, user satisfaction, and return on investment.
Ensure that the IS function is aligned with the overall business strategy. This involves
understanding the needs of the business and ensuring that the IS function supports these needs.
Continuously evaluate the effectiveness of the IS function and identify areas for improvement.
This may involve conducting regular audits, gathering feedback from users, and implementing
process improvements.
There are various theories and approaches to organizing the Information Systems (IS) function
within a business. Below are some of the most common ones:
The centralization vs. decentralization approach focuses on the degree to which the IS function is
centralized or decentralized within an organization. In a centralized structure, the IS function is a
separate department reporting to senior management, while in a decentralized structure, the IS
function may be integrated within different business units.
Business-IT Alignment:
The Business-IT Alignment approach emphasizes the importance of aligning the IS function with
the overall business objectives. This involves understanding the needs of the business and
ensuring that the IS function supports these needs. This approach requires strong collaboration
between the business and IT departments.
IT Governance:
The IT Governance approach focuses on the governance structure of the IS function. This
involves defining the decision-making processes and procedures for managing the IS function.
The IT Governance framework provides a set of policies, procedures, and controls for managing
the IS function.
IT Service Management:
The IT Service Management approach focuses on managing the delivery of IT services to the
organization. This approach emphasizes the importance of delivering high-quality services that
meet the needs of the business. IT Service Management is based on the ITIL (Information
Technology Infrastructure Library) framework.
Agile:
The Agile approach emphasizes the importance of flexibility and adaptability in managing the IS
function. This approach focuses on delivering value to the business through rapid development
and continuous improvement. Agile methodology is based on the principles of the Agile
Manifesto.
DevOps:
The DevOps approach emphasizes the collaboration between the development and operations
teams. This approach aims to improve the efficiency and quality of software development and
deployment. DevOps methodology emphasizes the use of automation and continuous delivery.
Ethical and Social issues of Information
Systems
Information systems (IS) play a vital role in modern society, but they also raise a range of ethical
and social issues. These issues arise due to the collection, storage, processing, and dissemination
of information.
Information systems have significant ethical and social implications. It is essential for
businesses, governments, and individuals to be aware of these issues and take steps to address
them. This includes implementing appropriate security measures, protecting privacy, promoting
digital citizenship, and ensuring that new technologies do not exacerbate social inequalities.
Privacy:
The issue of privacy arises due to the collection and storage of personal information by
information systems. Businesses and governments collect and store large amounts of personal
data, which can be misused if it falls into the wrong hands. Privacy concerns also arise from the
use of surveillance technologies.
Security:
Security is another critical issue for information systems. The use of information systems creates
new risks of unauthorized access, theft, and hacking. Cybersecurity breaches can lead to loss of
sensitive data, financial loss, and reputational damage.
Intellectual property:
Information systems make it easy to copy and distribute digital content, which raises issues of
intellectual property rights. Piracy of copyrighted material is a significant concern for the
entertainment and publishing industries.
Information systems are expected to provide accurate and reliable information. However, errors
in data entry, processing, and storage can lead to incorrect information being disseminated. This
can have severe consequences in fields such as healthcare, where incorrect data can lead to
misdiagnosis and incorrect treatment.
Social Inequality:
Information systems can create new forms of social inequality by creating a digital divide
between those who have access to technology and those who do not. This can create disparities
in access to education, job opportunities, and healthcare.
Employment:
Information systems can also have significant impacts on employment. Automation and artificial
intelligence can lead to job displacement, while new technologies require new skills and training.
Digital Citizenship:
The rise of social media and digital communication has created new challenges for digital
citizenship. Issues such as cyberbullying, online harassment, and fake news can have severe
social and psychological impacts.
Environmental Impact:
Information systems also have an environmental impact. The production and disposal of
electronic devices, as well as the energy consumption of data centers, contribute to carbon
emissions and environmental degradation.
Tackling ethical and social issues of information systems requires a multi-faceted approach that
involves several steps, including:
Start by identifying the ethical and social issues that arise from the use of information systems in
your organization. These may include issues related to privacy, security, intellectual property,
access, accuracy, reliability, and accountability.
Evaluate the impact of these ethical and social issues on your organization and its stakeholders,
including employees, customers, suppliers, and the broader community.
Develop policies and procedures that address the ethical and social issues identified in step 1.
These policies and procedures should be clear, concise, and easy to understand.
Monitor compliance:
Monitor compliance with the policies and procedures and take corrective action if necessary.
This may involve training employees, implementing new technologies, or revising policies and
procedures.
Regularly review and update the policies and procedures to ensure they remain effective and
relevant in light of changing ethical and social issues and the evolving use of information
systems.
Seek expert advice from legal, ethical, and social professionals to ensure that your policies and
procedures are legally and ethically sound and reflect best practices.
