McKinsey 7-S Framework
This framework can help you analyze how well a change can be implemented in an organization or can give
you an idea of the general well being of the organization. Problems arise when these seven components do no
reinforce one another.
Use this framework with caution, though, because it can be misused as a checklist and it is very easy to forget
one of the S’s during the interview. The seven factors are:
1. Strategy
2. Systems
3. Structure
4. Style
5. Staff
6. Skills
7. Shared Values
Product/Market Expansion Matrix
This framework can structure a discussion about growth options for a company. The options are whether to
grow in current or new markets and/or products. Each strategy carries different risks, with the diversification
strategy being the riskiest and the penetration strategy the most conservative.

Current Market Penetration Product Expansion

New Market Development Diversification
Product/Technology Life Cycle
This concept takes into account the passage of time when discussing the sales of a product or technology. Both
tend to go through four phases: introduction, growth, maturity, and decline.
If drawn in a diagram, the life cycle curve is S-shaped; thus, the name “Product/Technology S-Curve” is
sometimes used for this idea. Each stage requires a different strategy and management style. The model can
be especially useful when discussing the sales patterns of a new computer or other technology. The following
figure is an example of a generic S curve.
Introduction Growth Maturity Decline
Core Competency Analysis
C.K. Prahalad and Gary Hamel brought core competencies to the forefront of business strategy. Very briefly,
one of their ideas is that by analyzing which processes a firm executes very well, you can determine how they
may be able to expand their business into new, and sometimes unexpected, areas.
An example is Honda, who translated their core competency of engine building into cars, lawnmowers, boat
motors, motorcycles, etc. When in a case interview, think about what processes a company executes
particularly well and determine whether these processes could be valuable in different businesses. This
framework is often useful in analyzing the value chain of a business.
Relative Cost Position
The relative cost position of a firm can be determined by stacking up the variable costs and allocated (as best
possible) fixed costs of a unit produced by one firm to the costs of a unit produced by a competitor. The key
insights from this analysis can be (1) whether a company is more or less competitive with its competition and
(2) whether the company with the largest market share has the lowest unit costs. All else equal, this should be
the case because of experience curve effects. If it is not, the market leader may be vulnerable to price
competition by smaller firms.
Synergies
This idea is used in many settings, but it can be especially useful in analyzing the potential benefits of mergers
or acquisitions (a popular case interview topic). Synergies can come in many forms, but here are a few to look
for:
Spreading fixed costs over greater production levels
Gaining sales from having a larger product line and extending brands
Better capacity utilization of plants
Better penetration of new geographic markets
Learning valuable management skills
Obtaining higher prices from eliminating competition (beware of antitrust, though)
If a merger or acquisition offers none of these benefits and few others, you may wonder if all the transaction is
accomplishing is the creation of a bigger, not better, corporation.
