take current industry practices to the extreme

• focus of proven industry practices
• combine them innovatively to get better results

Values and principles

communication, simplicity, feedback, courage.

• Planning -> based on user stories
• Testing -> thorough testing at every step
• Pair programming -> watch, inspect, and trade off
• Simple designs -> based on agile modelling principles
• Refactoring -> redo and clean up as you go
• Collective code ownership -> egoless development, anyone can review and improve code
• Continuous integration -> grow the software continuously
• On-site customer -> get sign-off as you go
• System metaphor -> what should the final system look like? Small releases given to users frequently
• Forty-hour work week -> don’t overload the developers
• Coding standards -> follow industry standards for code

Three ring project approach
