CC-4CONSULTING CASE STUDIES CHAPTER 5 OF 7REVIEWED 2026-07-31

Business situation cases: diagnose and recommend

Integrate qualitative and quantitative evidence, divide the problem into workstreams, and finish with an implementation-ready answer.

A business case should show how analysis from separate branches becomes one decision. Otherwise the reader learns isolated calculations without synthesis.

WHAT THIS CHAPTER TEACHES

  • Separate symptoms from causes before recommending action.
  • Segment the problem by customer, product, geography, channel, time, or process step when those groups have different economics or behavior.
  • Assign major branches as workstreams with a clear question and output.
  • Read each exhibit’s title, units, period, axes, and definitions before interpreting it.
  • After each analysis, state the implication and update the working hypothesis.
  • Use the Minto Pyramid for the recommendation: action first, supporting reasons, quantified evidence, risk, owner, timing, and next test.

Example workstream handoff

Revenue workstream finding: Volume loss is concentrated in one customer segment and one channel.

Cost workstream finding: Fixed costs are stable; promotional spending rose without measurable conversion.

Operations workstream finding: The team can redirect promotion and service capacity within six weeks.

Combined answer: Stop the low-return promotion, target the affected segment through the stronger channel, and reallocate service capacity.

Implementation-ready synthesis

Name what happens, who owns it, when it begins, expected impact, principal risk, and the first checkpoint. “Improve customer retention” isn't a recommendation until the action is operational.

Diagnose before prescribing

A business situation case often begins with a symptom: falling profit, slow growth, poor customer experience, missed delivery, or rising cost. Separate the observed outcome from possible causes.

Segment the evidence

Break results by customer, product, geography, channel, time, cohort, location, or process step. The useful segmentation is the one that reveals different economics or behavior. Company averages often hide the problem.

Link workstreams

Revenue, cost, customer, operations, and capability analyses must be recombined. One workstream can show that volume loss is concentrated in a segment; another can show excess promotion; a third can show that service capacity can be reallocated. The recommendation follows from the combined evidence.

Exhibit interpretation

State:

  1. what the exhibit shows;
  2. the main pattern;
  3. why it matters;
  4. the next question.

Don't describe every bar. Check definitions and whether the chart supports causation or only correlation.

Financial analysis

Translate operational findings into revenue, cost, profit, cash, or investment. A recommendation should indicate expected magnitude and the assumptions required.

Options and prioritization

Generate possible actions, then compare impact, feasibility, timing, cost, risk, and reversibility. A long list isn't a strategy. Select the few actions that address the root cause and fit the constraints.

Implementation-ready recommendation

State action, owner, timing, resources, expected impact, risk, and checkpoint. If evidence is incomplete, recommend a pilot or analysis that resolves the most important uncertainty.

Worked pattern

A subscription business shows declining profit. Segmentation reveals that revenue is stable, but support cost and churn are concentrated among a newly acquired customer cohort. The recommendation isn't broad cost cutting. It is redesigning onboarding and eligibility for that segment while correcting the acquisition channel.

CURRENT AS OF 2026-07-31

Current case guidance emphasizes identifying important factors, analyzing data, and drawing conclusions. The chapter extends that logic into a connected workstream and implementation model.
