Key takeaways from our implementation: 1) Document as you go 2) Use feature flags 3) Practice incident response 4) Build for failure. Common mistakes to avoid: over-engineering early. Resources that helped us: Phoenix Project. The most important thing is outcomes over outputs.

One thing I wish I knew earlier: documentation debt is as dangerous as technical debt. Would have saved us a lot of time.

One more thing worth mentioning: we had to iterate several times before finding the right balance.
