5. Why? “How does a project get to be a year

   late?... One day at a time. ” -- Fred Brooks Brooks Law: "Adding manpower to a late software project makes it later!“ “No matter what the problem is, it's always a people problem.” --Gerald M. Weinberg

12. Software Development “ If debugging is the process of removing

    software bugs, then programming must be the process of putting them in. ” - Edsger Dijkstra

13. Source Control • Version Control System - (SVN/TFS/GIT) • Branching

    / Merging Standards • Feature Flags • Commit Message Standards • Check-in Policy • Continuous Integration
