Synthesis: the sixty-second recommendation that ends a case well

What is happening

At the end of a case the interviewer usually plays a senior client who has just walked in: “The CEO is here. What should we do?” Most candidates replay the analysis in the order they did it. A busy executive wants the opposite order: the answer first, then the reasons that support it, then what could go wrong and what happens next.

This is Barbara Minto’s pyramid principle applied to speech: the governing thought at the top, supported by a small number of grouped arguments, each backed by evidence. Its power is that the listener can stop at any level and still have the essential message. Its discipline is that you must decide what you think before you start talking.

Why it matters

The final minute is what the interviewer remembers when they write up the case, and the same structure decides whether your updates at work get read or skimmed.

The framework

The sixty-second synthesis

  1. Recommendation, in one sentence“We recommend X.” No preamble, no hedging.
  2. Three supporting reasonsEach with one number or fact from the case.
  3. The main riskWhat could make this wrong, and how you would watch for it.
  4. Next stepsTwo concrete actions with an owner or a timeframe.

Worked example

Roti Senja, synthesised for its CEO

“We recommend repricing the delivery menu and renegotiating your two largest ingredient contracts. Three reasons. First, costs rose Rp 11.4 bn against Rp 6 bn of new revenue, so margin fell from 15% to 10%. Second, delivery commissions alone rose about Rp 4 bn because delivery grew at in-store prices. Third, ingredient costs rose from 40% to 42% of revenue without any price change.

The main risk is that higher delivery prices reduce orders; we would test the new prices in three outlets for a month first. Next steps: the commercial team drafts delivery pricing this week, and procurement opens supplier talks before the next contract renewal.”

Continues the fictional case from “Profitability cases, worked through”.

What this means for you

StudentUse the shape for presentations and group assignments. Lecturers notice it as quickly as interviewers do.
Fresh graduateTake thirty seconds to prepare before you synthesise. Asking “may I take a moment to structure my answer?” is a strength, not a weakness.
Early professionalStart every email to a senior person with the recommendation or the ask in the first line.
Experienced professionalCoach your team to brief you in this shape. It doubles the number of decisions you can make in a day.

What to do

  1. Write the four-part synthesis for a decision you face this month, in under 120 words.
  2. Say it aloud and time it. If it runs past sixty seconds, cut the reasons, not the recommendation.
  3. Check that every reason contains a number or a fact.
  4. Do the drill below and compare your first sentence with the model.

Practice drill

Synthesise the gym case4 min, timed

Using the gym chain drill from the profitability piece (fee cut from Rp 400k to Rp 300k; members up from 8,000 to 10,000; monthly profit down from Rp 0.4 bn to Rp 0.1 bn; 11,200 members needed to restore profit), write a sixty-second synthesis for the chain’s owner.

  1. Decide your recommendation before writing anything else.
  2. Use the three numbers that matter most.
Show a model answer

“We recommend ending the open-ended discount and moving promotional members to a time-limited offer. First, profit fell from Rp 0.4 bn to Rp 0.1 bn a month because each member now contributes Rp 250k instead of Rp 350k. Second, restoring the old profit at the new price needs 11,200 members, 12% more than today. Third, the chain is only 400 members above breakeven, so any churn puts it in loss.

The risk is that new members leave when the price rises; we would offer them a three-month bridge rate. Next steps: stop the offer for new sign-ups this month and measure conversion of promotional members over the next quarter.”
