Reasoning & Writing Like a Strategist

Applying frameworks rather than naming them, critical reflection and proposition-building.

In plain English

Both the exam and the interview reward the same thing: a clear claim, a mechanism that explains why it is true, evidence, and honesty about where the argument breaks. Naming frameworks scores nothing; using one to reach a defensible conclusion scores everything.

The advanced view

A proposition-generating argument has four moves: identify the gap or tension in existing reasoning; specify the mechanism linking construct A to outcome B; state the boundary conditions and moderators under which it holds; and derive an observable implication that could falsify it. This is the structure of a theory paper and, compressed, of a good case recommendation.

Frameworks

Claim → mechanism → boundary

Say what is true, why it is true, and where it stops being true.

Pyramid principle

Answer first, three supporting arguments, evidence under each. Never build to the punchline.

Critical reflection

Name the assumption the framework makes and check whether this case satisfies it.

So-what test

Every analytical statement must end in a decision, a number, or a next step.

Framework criticism in one line each: Five Forces assumes stable industry boundaries and ignores complementors; RBV struggles to say how a resource is built; BCG assumes independent units and that share drives cost; disruption theory is often applied retrospectively; the Balanced Scorecard can multiply metrics without prioritising them. Saying one of these, and why it matters here, is what separates a top answer from a competent one.

Worked example — turning analysis into a recommendation

Step 1 of 9

  1. 1Finding: margin fell from 14% to 11% on revenue of 900.

Must know cold

  • Answer first, then the three reasons, then the evidence.
  • Every framework has an assumption; name it before you rely on it.
  • Quantify the size of the problem before recommending the fix.
  • Say what would change your mind — that is critical reflection, scored explicitly.

Common pitfalls

  • ×Framework tourism: touching five models and concluding nothing.
  • ×Recommendations without a number attached to the upside.
  • ×Hedging every claim so that no decision follows.
  • ×Confusing description of the case facts with analysis of them.

Exercises

Try each one on paper before revealing the worked solution.

Exercise 1

Write a proposition about why some acquirers create value from serial acquisitions while others do not, in the claim-mechanism-boundary format.

Statistics glossary for this phase

The terms an interviewer expects you to use precisely — with the pitfall attached to each.

Order of magnitude

The nearest power of ten of a quantity.

In finance

In market sizing, being right to a factor of two beats being precise and wrong.

Pitfall

×Losing a factor of 1,000 between thousands, millions and billions late in the arithmetic.

Weighted average

Average where each value counts in proportion to its size.

In finance

Blended margin, blended price, WACC — all weighted averages.

Pitfall

×Using unweighted averages across segments of very different size.

Rate, base, mix

Any total is a base times a rate; the mix says which bases carry which rates.

In finance

The standard decomposition when a margin moves without any single rate changing.

Pitfall

×Blaming pricing for a mix shift, or vice versa, without splitting the two.

Mean (average)

Sum of the values divided by how many there are.

In finance

The base case in any sizing or margin estimate: revenue per customer, ticket size, cost per unit.

Pitfall

×Averaging averages. Average margin across segments is only valid when weighted by revenue.

Median

The middle value once the data is sorted.

In finance

Use it for skewed data such as deal sizes, household income or customer spend.

Pitfall

×Quoting a mean where a few whales dominate makes the typical customer look far richer than they are.

Practise this

The drills and cases where this phase turns into arithmetic you do out loud.
