Summary

PM case interview at Cisco where they dropped a pretty niche product on me: remote-controlled shower water heaters. Had to define a problem statement and sketch out an MVP from scratch. Not the kind of domain you prep for.

Suggested Approach

Start by clarifying the product context and target user, then define a crisp problem statement that highlights the core pain point. Next, outline a lean MVP that tests the riskiest assumptions with minimal features, and finally propose success metrics and next steps.

Pro tip: Anchor your MVP around a single high-value use case (e.g., scheduling hot water for morning showers) to avoid overbuilding, and emphasize learning goals over feature completeness.

1. Clarify Context and User

Ask clarifying questions about the target market (e.g., homeowners, renters), existing solutions, and constraints. Identify the primary user persona and their shower water heating pain points.

2. Define the Problem Statement

Craft a concise problem statement that captures the user need, the gap in current solutions, and the impact. For example: 'Homeowners waste time and energy waiting for hot water or manually adjusting heaters; they need a convenient, remote way to control shower water temperature and timing.'

3. Identify Assumptions and Risks

List key assumptions (e.g., users want remote control, they value scheduling, they have compatible heaters) and prioritize the riskiest ones to test in the MVP.

4. Outline MVP Features and Scope

Define the minimal set of features that address the core problem and test assumptions. For example: a mobile app to remotely turn on/off the heater and set a target temperature, with basic scheduling. Exclude advanced features like voice control or AI learning.

5. Define Success Metrics and Next Steps

Specify metrics to validate the MVP (e.g., % of users who schedule a shower, reduction in wait time, energy savings). Outline a plan to iterate based on feedback and data.

Key Points to Mention

  • Target user persona and their specific pain points (e.g., busy professionals, families)
  • Clear problem statement that focuses on convenience, energy efficiency, and time savings
  • Prioritization of features based on impact vs. effort, focusing on core remote control and scheduling
  • Technical feasibility and integration with existing water heaters (e.g., Wi-Fi, compatibility)
  • Success metrics such as user engagement, time saved, and energy consumption reduction
  • Iterative approach: start with a simple MVP, learn from user feedback, and scale
