Product Design Prompt: Modern Supermarket Experience

Pick one focus area for a modern supermarket and go deep:

  • In-store layout.
  • Checkout flow.
  • Inventory discovery.
  • Loyalty program.

Your task:

  1. Start with clarifying questions.
  2. Define target users and key jobs to be done.
  3. Describe MVP features.
  4. Outline implementation and success measurement.

Constraints & Assumptions

  • Choose one focus area and go deep rather than lightly covering all four.
  • Consider store operations, accessibility, shrink, payment methods, staffing, and customer behavior.
  • Include metrics and guardrails.
  • If you choose checkout, balance speed with loss prevention and inclusivity for non-digital users.

Clarifying Questions to Ask Guidance

  • What store format are we designing for: urban convenience, large grocery, warehouse, or premium market?
  • Which user segment matters most: express shoppers, weekly shoppers, budget-conscious shoppers, families, or store associates?
  • What technology and integrations exist: POS, loyalty, app, inventory, self-checkout, computer vision, or handheld scanners?
  • What payment methods and accessibility requirements must be supported?
  • What shrink or fraud tolerance applies?

Part 1 - Users and Jobs

Define target users and jobs to be done for your chosen focus area.

What This Part Should Cover Guidance

  • Shopper segments and associate needs.
  • Primary pain points and moments of friction.
  • Operational constraints and business goals.
  • Accessibility and inclusion.

Part 2 - MVP Features

Describe MVP features for the chosen focus area.

What This Part Should Cover Guidance

  • A focused feature set.
  • User flow.
  • Associate workflow.
  • Edge cases.
  • Fraud, safety, or operational controls.

Part 3 - Implementation and Metrics

Outline implementation plan and success measurement.

What This Part Should Cover Guidance

  • Pilot plan, integrations, training, and rollout.
  • Primary, secondary, and guardrail metrics.
  • Experiment or store-level test design.
  • Risks and mitigations.

What a Strong Answer Covers Guidance

A strong answer picks one supermarket experience, designs for real shopper and store-associate behavior, handles operational constraints, and defines measurable success without ignoring shrink, accessibility, or adoption risk.

Follow-up Questions Guidance

  • How would you serve customers who do not use smartphones?
  • What if the solution increases shrink?
  • What would you pilot first?
  • How would you train associates?
  • What metric would make you roll back the MVP?
