What's it about?

Today is about shooting for code perfection, not results & output.
  • 5 sessions
  • Same exercise, different constraints
  • Pair programming
  • Retrospectives at end of each session
  • It's a day for you, constraints are just a guide
What is Code Retreat - not Getting Things Done Not really about perfection - trying different approaches Constraints are there to help you think about things in different ways. What you're going to get out of it - TDD/Agile/Pair Programming You're in control. It's about making the most of the time/space
