Summary

PM case question at Meta, one of those strategy prompts where they drop you into a completely different industry and expect you to think through it cold. Just the one question but it had a lot of surface area.

Suggested Approach

Start by clarifying the problem: define the decline (e.g., sales metrics, timeframe, geography) and hypothesize why Instacart and Blue Apron might be impacting Trader Joe's. Then, structure your answer by diagnosing root causes, segmenting customers, and proposing product-led solutions that leverage Trader Joe's unique value proposition.

Pro tip: Acknowledge that correlation does not imply causation—Instacart and Blue Apron may be symptoms of broader shifts in consumer behavior, not the sole cause. Show you can separate signal from noise by validating hypotheses with data.

1. Clarify and Scope

Ask clarifying questions to understand the decline: which cities, what timeframe, what metrics (revenue, foot traffic, basket size)? Define the problem precisely before jumping to solutions.

2. Diagnose Root Causes

Hypothesize why sales are declining in those cities. Consider factors like convenience (Instacart), meal-kit substitution (Blue Apron), changing demographics, or competitive intensity. Use data to validate or invalidate each hypothesis.

3. Segment and Prioritize

Identify which customer segments are most affected and their needs. Prioritize segments based on impact and strategic fit for Trader Joe's (e.g., urban professionals, families).

4. Ideate Solutions

Brainstorm product and experience solutions that address the root causes. Consider partnerships, in-app experiences, delivery, loyalty programs, or unique in-store offerings that reinforce Trader Joe's brand.

5. Evaluate and Recommend

Assess solutions using criteria like impact, effort, and alignment with Trader Joe's strengths. Recommend a prioritized roadmap with metrics to track success.

Key Points to Mention

  • Distinguish between correlation and causation—Instacart and Blue Apron may not be direct causes.
  • Consider Trader Joe's unique value proposition: curated products, low prices, fun in-store experience.
  • Segment customers by behavior (e.g., convenience seekers vs. experience seekers) and geography.
  • Explore partnership opportunities with delivery platforms rather than competing head-on.
  • Leverage data to measure impact and iterate on solutions.
  • Think about both short-term tactics (e.g., promotions) and long-term strategy (e.g., digital transformation).
