Chaos and resilience testing
Track resilience experiments, hypotheses that held and weaknesses fixed.
Reliability & managed IT servicesHow it's worked out
- Coverage = services tested ÷ critical services. Fix rate = fixed ÷ found
- Experiments in production or a production-like environment
NoteA failed hypothesis is a success: it found a weakness before customers did. Track fixes, not just experiments.
