Find and Fix the Most Damaging Failure in Instacart's Grocery Delivery Experience

You are the product manager for the delivery experience at Instacart. The CEO asks you to find the worst experience customers have with their deliveries and fix it. Explain how you would decide which experience is the worst, what you would change, and how you would know the fix worked. ```hint Define "worst" first Worst could mean the most common failure, the most damaging one or the most expensive one. Decide how you would rank failures across the whole order, from checkout to after the bags arrive, and what evidence would settle the ranking. ``` ### Clarifying Questions - Does "worst" mean the single most painful failure across all orders, or the experience of the customers whose orders go most wrong? - Should the fix consider only customers, or also the shoppers and stores involved in every delivery? - Did something prompt the request, such as rising complaints, lower ratings or churn in particular markets? - Is this a quick win for this quarter or a longer program, and what team do I have? ### What a Strong Answer Covers - A map of the delivery journey from checkout to after delivery, including the shopper's and the store's part in it. - A way to rank failure modes by frequency, severity and effect on reordering, using data the company would already have such as support contacts, refunds and ratings. - A clear choice of one failure to fix, with root causes on the customer, shopper and store sides. - Prioritized solutions and a first experiment. - Success metrics with guardrails, including shopper efficiency and the cost of credits. ### Follow-up Questions - Your fix cuts complaints but adds two minutes to every shopping trip. How do you decide whether it is worth it? - How would you handle orders that never arrive at all, which are rare but severe? - What would you show the CEO after one month, before retention data is available?
