Summary

Interviewed for a BA role at Microsoft and got hit with a competitive analysis case. Pretty standard stuff for that level but I fumbled the structure more than I'd like to admit.

Q1

A competitor is gaining market share. How would you investigate why?

Author's notes

I jumped straight to 'look at their pricing' which, in hindsight, was way too narrow.

Suggested Approach

Start by clarifying the scope and defining what 'gaining market share' means in terms of metrics and timeframe. Then outline a structured investigation that combines quantitative data analysis with qualitative research to identify root causes, and finally propose actionable next steps.

Pro tip: Emphasize that you would validate hypotheses with data before jumping to conclusions, and mention the importance of considering both internal and external factors. This shows analytical rigor and business acumen.

1. Clarify and Define

Ask clarifying questions to understand the context: which competitor, what market segment, what timeframe, and how market share is measured. Define the problem precisely to avoid scope creep.

2. Gather Data

Collect quantitative data from internal sources (sales, customer feedback, product analytics) and external sources (industry reports, competitor announcements, web traffic). Identify trends and anomalies.

3. Form Hypotheses

Based on data, brainstorm potential reasons for the competitor's gain: product features, pricing, marketing, customer experience, or external factors. Prioritize hypotheses by likelihood and impact.

4. Test Hypotheses

Use A/B tests, customer interviews, win/loss analysis, and competitive teardowns to validate or invalidate each hypothesis. Look for correlations and root causes.

5. Recommend Actions

Synthesize findings into actionable recommendations for product, marketing, or strategy teams. Suggest metrics to monitor and a plan to iterate.

Key Points to Mention

  • Define market share metrics (revenue, units, active users) and segment by geography, product line, or customer type.
  • Use both quantitative (analytics, surveys) and qualitative (customer interviews, sales calls) methods.
  • Conduct win/loss analysis to understand why customers choose competitors.
  • Perform competitive teardown to compare features, pricing, and user experience.
  • Consider external factors like market trends, regulatory changes, or economic shifts.
  • Prioritize hypotheses using frameworks like impact/effort or likelihood/impact matrix.
