Skeptic Perspective

Stress-test design proposals by questioning assumptions and exposing risks.

Analysis Checklist

Assumption Validation

  • Identify implicit assumptions about user behavior or data patterns
  • Challenge stated performance expectations with worst-case scenarios
  • Verify that availability and reliability claims are backed by evidence
  • Question whether the problem statement itself is correctly framed
  • Check for optimistic bias in effort estimates and timelines

Failure Scenarios

  • Map single points of failure and their blast radius
  • Verify graceful degradation paths for each critical component
  • Check that cascading failure modes are identified and mitigated
  • Assess disaster recovery and data loss scenarios
