➘ Time consuming “The script has been frozen for 30
minutes, should I worry?” - A worried developer
➘ Maintenance “It works, but I can’t figure out why”
- Both of us
➘ Lack of expertise “I’ve only been there for 3

together? - How to avoid conflicts? - How to foster expertise?
- Micro-startups - Independant teams - Focus on a specific
domain - Multi-skills - Limited lifespan Team work

- Easy to understand - Fast to test, fast to
deploy - Framework - Open-source - No more conflicts
