Problem structure and hypotheses

Part of the Consulting learning and recruiting path. Read the explanation and example, attempt the task, then open the self-check.

Understand

Turn ambiguity into testable subquestions. Minimise overlap and cover key drivers. Clarify objectives, definitions and constraints before choosing a framework. A hypothesis is provisional.

Worked example

Split declining profit into revenue and costs, then revenue into price, volume and mix. Locate the change before proposing marketing.

Examples and numbers are educational, not employer questions, live market data or hiring criteria.

Practise and keep your output

Build a three-level issue tree for a cafeteria profit decline, with required evidence at each leaf.

Keep inputs and sources, assumptions, steps, results and uncertainties in your own document. Attempt independently before checking below.

After attempting: answer and self-check

Distinguish revenue, costs and fixed/variable drivers. Give every branch a verification method.
