Identify Causes and Solutions for Fashion Profit Decline

Timed Case: Fashion Retail Profit Decline — Diagnose and Recommend

Context

You are analyzing a fashion retailer whose profit has declined year-over-year. Assume you have typical retail exhibits for the last 12–18 months vs. prior year: category/SKU, channel, region, price, units, revenue, discounts/markdowns, returns, variable fulfillment/shipping, COGS, and fixed costs.

Task

  1. Quantitatively decompose the profit decline into drivers (price, volume, mix, discounting/markdowns, returns, variable costs, fixed costs, channel/category mix, etc.). Identify the top drivers by dollar impact.
  2. Propose 2–3 actionable, data-backed initiatives to restore profitability, with rough impact sizing and how you would validate them (experiments/causal analysis).
  3. Deliver a concise 60-second executive summary suitable for senior leadership.

Deliverables

  • Driver diagnosis (clear, MECE, quantified) with brief methods/assumptions.
  • 2–3 prioritized initiatives with back-of-the-envelope impact and a validation plan.
  • A 60-second executive summary script.

Guidance

  • Prioritize issues with the largest quantitative impact.
  • Keep the final summary MECE, clear, and persuasive.
  • Make minimal, explicit assumptions where the exhibits are incomplete.

Clarifying Questions to Ask Guidance

  • Clarify the business objective, unit of analysis, time window, exposure definition, and primary metric.
  • State assumptions about instrumentation, randomization, sample size, and data quality.
  • Separate descriptive analysis from causal claims.

What a Strong Answer Covers Guidance

  • A metric framework with primary, guardrail, and diagnostic metrics.
  • A credible analysis or experiment design with clear assumptions and bias checks.
  • SQL/statistical logic for segmentation, variance, confidence, and data validation where relevant.
  • An actionable recommendation that explains trade-offs and next steps.

Follow-up Questions Guidance

  • What sanity checks would you run before trusting the result?
  • How would you handle novelty effects, seasonality, or selection bias?
  • What decision would you make if metrics disagree?
