Strategies For Success

19


Do Implement Continuous Integration

20

21 http://en.wikipedia.org/wiki/Margaret_Hamilton_%28scientist%29


Do Not Create Environment Specific Packages

22


Do Externalize Environment Specific Configuration

23


Do Automate Everything

24


Do Not Assume Existing Processes Are Right (Engage In Continuous Improvement)

25

!


Do Not Use A Different Process For Different Environments

26


Do Recreate App Environments Frequently (Also Known As: Servers Are Not Puppies)

27


Do Ensure Database Changes Are Automated
