User Research & Validation Plan

Key Assumptions to Validate

Assumption Risk Method Target
Engineering teams discover API changes through production incidents High Interviews, incident analysis 70%+ confirm this happens monthly
Teams track 20+ external APIs on average Medium Usage survey, package analysis Average of 15+ APIs per team
Manual changelog checking is inconsistent and missed High Process interviews, task analysis 80%+ admit to inconsistent checking
Teams will pay $49/month for API monitoring Critical Pricing tests, pre-orders 10+ pre-orders at target price
Email alerts alone are insufficient for critical changes Medium Communication preference survey 60%+ need Slack/other channels
Teams need impact analysis beyond just notifications High Problem interviews, solution tests 75%+ want code impact mapping
API response diffing (undocumented changes) is valuable opt-in Medium Feature prioritization survey 50%+ would enable if free
Teams have dedicated time for API dependency management High Process interviews, time logs Only 30%+ do this systematically

Customer Discovery Interview Guide

Part 1: Background & Context (10 min)

  • • Tell me about your role and what you do day-to-day
  • • How long have you been in this position?

  • • How many third-party APIs does your team currently use?
  • • What are your main responsibilities regarding external dependencies?

Part 2: Problem Exploration (20 min)

  • • Walk me through the last time an API change caused a problem in production
  • • How often do you check changelog pages for your APIs?
  • • What triggers you to check for API updates?
  • • How does it feel when you discover breaking changes during deployment or in production?
  • • What's the worst part about managing API dependencies?
  • • What have you tried to solve this problem?
  • • How much time do you spend on API dependency management each month?

Part 3: Current Solutions (15 min)

  • • What tools or methods do you currently use to track API changes?
  • • What do you like about your current approach?
  • • What frustrates you about these tools?
  • • Have you ever switched tools for API monitoring? Why?
  • • What would make you switch to a new solution?

Part 4: Solution Exploration (15 min)

  • • If I told you there was a tool that automatically tracks all your API changes and alerts you before they break production...
  • • What would be most valuable about that?
  • • What concerns would you have about such a tool?
  • • What features would it need for you to try it?
  • • How much would you expect to pay for something like this?
  • • Who else would need to approve this purchase in your organization?

Part 5: Wrap-up (10 min)

  • • On a scale of 1-10, how painful is API dependency management for your team?
  • • How important is it to solve this problem in the next 3 months?
  • • Would you be interested in being a beta tester for a solution like this?
  • • Who else should I talk to about this problem?

8-Week Validation Plan

Weeks 1-2 Problem Validation
• Conduct 10-15 customer discovery interviews
• Send screening survey (target 200+ responses)
• Analyze interview transcripts for pain patterns
• Document validated vs. invalidated assumptions
Weeks 3-4 Solution Validation
• Create landing page with 3 headline variants
• Run A/B test with $500 ad spend
• Launch waitlist (target 100+ signups)
• Follow up with 20 survey responses for deeper feedback
Weeks 5-6 Willingness to Pay Validation
• Conduct 10 pricing interviews
• Run Van Westendorp pricing survey
• Test fake door with pricing tiers
• Attempt 5-10 pre-orders at target price
Weeks 7-8 Prototype Validation
• Build Wizard of Oz MVP for 10-20 users
• Deliver manual change detection service
• Collect NPS and qualitative feedback
• Iterate on core value proposition based on learnings
