2 types of people: waiters and changers
2 relationships:
- waiter - changer
- changer - changer (breaking api changes)
---
4 levels of insight into design
1) there's changes
2) there's 2 types of changes: structure & behavior
3) there's a sequence, which you can plan ("I can change this structure, so I can do that behavior change easier")
4) experiment: make pull requests with only behavior or only structure, get into prod
user visible changes at the end of the sequence
---
flexibility of moving behaviour forwards or backwards
waiter -> get's steady flow of changes
changer -> keep api steady, implement in terms of old api, then help implement new api
