environment build process iii. Environments will be stable, reliable, consistent, & secure c. CREATE OUR SINGLE REPOSITORY OF TRUTH FOR THE ENTIRE SYSTEM i. ALL parts (code & environments) of the system are shared accepted into GWS without accompanying automated tests. Spread Testing Grouplet team approach. Google – single, share repository of billions of files. 50% of code is changed each month. 40K code commits/day feedback kills – larger batch sizes compound effort needed to identify causes ii. Unit tests – test a single method, class, or function in isolation to ensure operates as designed iii. Acceptance tests –

RISK-TAKING i. Leaders reinforce the culture through their actions ii. Roy Rappaport, Netflix – a single engineer had been responsible for taking down Netflix twice in 18 month span. He wasn’t fired, he is in direct proportion to the degree to which its policies are expressed as code.” c. CREATE A SINGLE, SHARED SOURCE CODE REPOSITORY FOR OUR ENTIRE ORGANIZATION i. Firm-wide shared source code repository Deployment pipeline tools 5. Monitoring and analysis tools 6. Tutorials and standards ii. Google – Single repository with over 1B files and over 2B SLOC, over 25K engineers for every Google property d
