• Teams email updated files to each other
• Keep history of files named xxx.bak1, xxx.bak2
• Developers “pass the spoon” around
• Manual FTP of files to deploy

13. • We use SVN (for now)
• Many developers work together on many projects
• Any developer can work on any file on any project at any time
• We use a hosted solution, Beanstalk, which we’ll introduce in the workshop

14. • Branch for development, staging and trunk
• All developers work automatically deployed from development
• Client signs off work on staging
• We deploy to production from trunk
• We create short lived feature branches as required

15. • We know every change to every file in every deployment, ever
• Problem with a website, we start with what changed and who changed it
• Lead developer can easily monitor important changes or new starters
• Our clients have access to review and can also commit changes
