30-Day Challenge – teams work with dedicated Dojo coaches and engineers, execute 2-day sprints to generate breakthroughs. Teams regularly achieve results in days that previously would have taken 3-6 months environment is put in place, it must be monitored to ensure it stays in known good states ii. Generate automated tests for appropriate settings and use the tests to scan environments for vulnerabilities board is required, aim for quick deployment even if manual steps are required ii. Use tooling to generate the artifacts needed for approval. Share evidence and artifacts from the pipeline to support.

workii. If it was important enough for an engineer to implement, it is certainly important enough to generate enough production telemetry so that we can confirm that is it operating as designed and outcomes Create infrastructure to make it easy for Dev or Ops to create telemetry for functions built ii. Generate graphs with overlays of production changes iii. Tools – StatsD, JMX, codahale, New Relic, Prometheus
