Leverage the friction/pain to drive/focus improvement efforts

What might such a diet entail?

• More frequent reviews/approvals/integration/testing/deployment• Changes to working teams• Leaner processes with fewer/lighter gates • Higher quality built in to avoid downstream blockages in

Test/Deploy/Production• Investment in automation/tooling in Dev/Ops to enable higher

frequency• Different metrics and score-cards used to govern the organization• More DevOps-oriented organizational structure

Other steps are context-specific… You will have to find out!

DevOps == Continuous Deployment?
