The document discusses structured problem solving and hypothesis generation. It explains that structured problem solving is a formal approach to organizing thinking. The key aspects are defining the problem, developing hypotheses to prove or disprove potential causes, and structuring the analysis using logical frameworks. Hypothesis generation aims to identify the root cause of an issue by stating what the issue is, what causes it, and what the impact is. Developing good hypotheses involves asking questions, validating initial hypotheses, thinking outside the box, and using abduction, which is a variation of deductive and inductive reasoning.

3. What is Structured Problem Solving?
Structured problem solving is a formal approach to
organizing peoples’ thinking
1. Define the Problem
• Understand the problem statement
• Facilitate understanding of the issue
2. Develop a Hypothesis
• Used to prove (or disprove) our logic
• Which if ―true‖ we can use to solve the underlying cause
3. Structure the Analysis
• Use a logical framework to analyze the problem
• Use the Root Cause Analysis to group your ideas
To help you solve a problem, your structure must disaggregate the problem into
smaller and easier to solve components.

4. Our problem solving approach begins by answering a simple series
of questions
• Is there a problem or opportunity? DEFINE THE
PROBLEM
• If so where does it lie?
IDENTIFY
ROOT CAUSE
• Why does it exist?
STRUCTURE
THE ANALYSIS
• What could we do about it?
• What should we do about it? FIND THE
SOLUTION

8. Typically, logical pyramids help you to define, disaggregate, structure and
ultimately, solve the business problem
To understand the problem, assertions or ideas must be:
• Summaries of the ideas grouped below them
• The same kind of idea, and they must answer the same question implied by their
summary
• In a logical order:
- Deductively or inductively
- Trace course or time order
- Divide or structural order (e.g., Sales, Marketing, Manufacturing, etc.)
- Classify or degree order (e.g., most important, 2nd most important, etc.)

the power of logical pyramids as the preferred communication style:

11. A hypothesis should identify not only the issue but also the cause and the
impact
Think through these 3 stages as you create a hypothesis to help
you plan out how you will test it:
What is the issue?
―X is xxx‖ or ―X is an
• What is the underlying opportunity? opportunity …‖
• Where is the advantage?
What do you think causes the issue?
―… due to …‖
• What are the key drivers of the process?
What is the impact of the issue?
• How can we tell there is an opportunity? ―… resulting in …‖
• Why do we care?

12. Hypotheses are developed in 3 steps
1 • What are the real strategic issues?
Define the • What is the impact on the Is there a market for white label
question organisation? insurance products?
• What are the priorities?
2 • We believe this to be true . . . • Direct channels are growing
Review and
Describe • A series of statements, not yet • Retailers have a strong
Multiple backed by data channel and brand
Assertions • Based on initial data search or • There are existing products
expert opinions
3 • We think . . . Chubb Insurance can access
• It looks like . . . new business by using the
Form the
brand strength of Tesco
hypothesis • The right answer may be . . . resulting In low cost acquisitions
• The options could be . . . and profitable business
A number of assertions need to be true for a hypothesis to be valid.

13. How to find a good hypothesis
Start by Asking Questions:
• Talk to lots of people about the core problem
• Brainstorming during case team meeting
• Ask ―5 Why’s‖
Validate Your Initial Hypothesis:
• Assume perfect rationality — how should the business system behave?
• Look for analogies (other industries or problems)
• Imagine that you had perfect information — what would the ideal analysis look like?
Think outside the Box:
• Think about the problem from a different angle
• Talk to people who think differently
14
14. What if your hypothesis is proven wrong?
You Win!
Hypothesis-driven thinking requires frequent reviews of the
prevailing and current hypotheses:
Do we still think they are right?
Are we making progress towards disproving them?
Are they at the right level of generality/predictiveness?
If proven wrong you’ve already made a big step towards
answering your question!

15. Another powerful tool to for hypothesis development is abduction—which
is a variation on deductive and inductive reasoning
1. Rule Rule If we put the price too
high, sales will go down
Case We have put prices too
Deduction 3. Result high
2. Case Result Therefore, sales will go
down
1. Case Case We have put prices up
Result Sales have gone down
Induction 3. Rule
Rule Sales have gone down
because the price is too
2. Result
high
1. Result Result Sales have gone down
Rule Sales go down when
prices are too high
Abduction 3. Case
Case Probably we have put
2. Rule prices too high
