Fictional practice, not an employer interview question.
A fictional business improves one team's response time by transferring complex cases to another team. The local dashboard improves while end-to-end resolution worsens. Map the full journey before recommending a staffing or process change.
Work through the case
Build or write this
Prepare a flow diagram, a small capacity calculation and a recommendation with explicit tradeoffs. Consulting candidates can synthesize; analysts can investigate case mix; implementation candidates can define handoff responsibilities.
Stress-test the decision
Double the share of complex cases. Explain which bottleneck changes and what you would measure in a pilot. Keep the exercise clearly fictional rather than implying knowledge of the firm's client cases.
Turn the exercise into application evidence
Use only your own work, public material or an authorized sandbox. Write the problem, your decision, the test and the limitation in a short case study. A diagram or a focused analysis is acceptable when code is not relevant to the role. Do not claim the exercise reproduces the employer's systems or guarantees an interview.
Prepare your application
For Oliver Wyman, connect structured problem solving to the sector and role you are targeting. Show enough detail to defend your assumptions without turning an answer into a recital of frameworks. Relevant specialist experience can be valuable only when its contribution to the decision is clear.
