day every exercise and new piece of information is evaluated and debated; more similar to R&D lab. f. REDEFINE FAILURE AND ENCOURAGE CALCULATED RISK-TAKING i. Leaders reinforce the culture through their fast flow, deployability, and operations will derive NFRs. Codify these into the tests and pipeline f. BUILD REUSABLE OPERATIONS USER STORIES INTO DEVELOPMENT i. Goal – make recurring work as repeatable conferences, give talks, and then sharing back to the organization what was learned ii. Attend Meetups! f. CREATE INTERNAL CONSULTING AND COACHES TO SPREAD PRACTICES i. Capital One – SMEs hold open office

Slow and periodic feedback kills – larger Enable fast flow through common promotion process anyone can run without manual steps and handoffs f.
