The McKinsey 7 S framework or model for strategic
fit was developed over thirty years ago by strategy
consultants McKinsey and in particular Tom Peters
and Robert Waterman, co-authors of the classic book
“In Search of Excellence” to help implement
strategies.
What Is The McKinsey 7 S Framework?
It was originally thought that to implement strategy
you needed to align strategy with structure (and vice-
versa).
This wasn’t enough and McKinsey developed the 7-S
model to show that a softer set of issues also needed
to be considered when implementing strategy.
5. McKinsey & Company | 1-4
The 7 S’s are:
•Strategy – how the business intends to create a competitive advantage
and achieve its overall goals.
•Structure – the hierarchy of responsibility and accountability within the
organisation and how the business is organised functionally,
geographically or by product-market.
•Systems – the way activities and processes get the work of the business
done effectively and efficiently.
•Style – the culture of the business and the way the leaders behave
towards customers, employees and other stakeholders. What’s said is
much less important than what’s done.
•Staff – the personnel within the business and their individual skills,
abilities and attitudes. Different people are right for different
organisations.
•Skills – specialist skills that the business has access to through the
combination of systems and staff – think core competences or distinctive
capabilities.
•Shared values or subordinate goals depending on which version you
read – the core values and beliefs of the business.

transnational company
A commercial enterprise that operates substantial facilities, does business in more
than one country and does not consider any particular country its national home.
One of the significant advantages of a transnational company is that they
are able to maintain a greater degree of responsiveness to the local markets where
they maintain facilities.
7. McKinsey & Company |
A transnational corporation (TNC) differs from a traditional MNC in that it does not identify itself
with one national home. While traditional MNCs are national companies with foreign
subsidiaries,[9] TNCs spread out their operations in many countries sustaining high levels of
local responsiveness.[10] An example of a TNC is Nestlé who employ senior executives from
many countries and try to make decisions from a global perspective rather than from one
centralized headquarters.[11] Another example of a Transnational Corporation is the Royal
Dutch Shell corporation whose headquarters may be in The Hague, Netherlands but its
registered office and main executive body where the decisions are made is headquartered
in London, United Kingdom.

What is a good problem definition?
▪ What are characteristics of a good problem
definition?
▪ What are “must-have” elements to
– Ensure we get to the best answer?
– Ensure our answer is practical and
implementable?
▪ What are the common pitfalls?
A ‘problem definition’ is a way to frame a problem so that
we are clear up front on what we are trying to solve, and
what success will look like
14. McKinsey & Company | 13
Problem statements help sharpen your thinking about the problem
What are we trying to achieve?
Focuses the work and ensures that findings can be acted on. The more specific the statement the
better, provided that it is not so narrow that the “wrong” problem is addressed.
Background and context
Potential challenges
Comments on the “situation” and “complication”
facing the key decision-maker (e.g., industry
trends, relative position in the industry).
Indicates what will not be included in the project
(e.g., international markets, R&D activities). Also
defines the limits to the set of solutions that can be
considered, including degree of accuracy of
analysis (i.e, 80/20 rule vs. 90/10).

What is success?
Stakeholders
Refers to the basis on which the key decision-
maker will decide whether to act on the
recommendations (e.g.,financial returns, effect on
staff, market share growth).
Identifies primary decision makers (e.g., CEO,
Division Manager) as well as internal and external
parties who can affect implementation (e.g.,
shareholders)

Where will we find information and help?
Describes implementation challenges (e.g., labour relations, communication practices, risk aversion)
that must be addressed to change beliefs and behaviors

One idea of what a good problem definition looks like…
What are we trying to achieve?
The basic question we are trying to solve. It should be SMART: specific, measurable,
action-oriented, relevant and time-bound.
Background and context
Potential challenges
What is the current situation?
What has happened so far?
Why is this problem is being addressed
now?
What are the potential issues or problems
that we can forsee and plan to mitigate?

Problem statement
Characteristics of good problem statement
• Specific
• Measurable
• Action-oriented
• Relevant (to the key problem)
• Time-bound
17. McKinsey & Company | 16
Example problem statement: Oilco refinery
The Oilco refinery is suffering from
poor profitability despite a strong
market niche position
Should the Oilco refinery improve
its deteriorating position?
Can the Oilco refinery be
managed differently to increase
profitability?
Too general
Not disputable
Statement of fact
18. McKinsey & Company | 17
Good problem solving: Oilco refinery
What opportunities exist for Oilco to improve
profitability by $40 million per year through
overhead rationalisation, operational
improvements, or restructuring non-core
assets?

What is an issue tree and why is it important?
A problem solving tool that breaks a problem into discrete chunks
Why use logic trees?
▪ To break a problem into
component parts
▪ To ensure integrity of the
problem solving is maintained
▪ To build a common under-
standing within the team of
the problem solving
framework
▪ To help focus team efforts

The issue tree is a valuable tool to disaggregate a problem into core sub-
questions that need to be addressed to answer the main question
Description Why use it? When to use it?
▪ Early in the
problem solving
process, when
you know little
about the
problem
▪ Decomposes an
issue into smaller
sub-issues (e.g.,
measures, criteria)
▪ Sub-issues answer
the question
“What?” or “How?”
▪ Helps
disaggregate
problem into
individual pieces
▪ Helps divide the
work among
team members

Methods for prioritising
Key ideas
• Take a reasonably quick, informal
approach to get started
• Remember that sometimes a ”back
of an envelope” calculation is all
that’s needed
• If new information emerges, you can
always reprioritise and switch your
efforts to another part of the tree
• Use likely impact to decide where to
go first
• Use readily available data whenever
possible; avoid major data requests
• Do not create massive spreadsheets
or other computer models if you can
move forward with less complete
information
Example methods
• Percentage of total “X”
• Estimated potential
increase/decrease (sensitivity
analysis)
• Simple ratios
• Quick industry benchmarks
• Qualitative input from interviews
• Ease of implementation
• Timing
• “Quick wins”
• Available resources
• High/low risk
