good list.
I just want to add more voice to the unit testing part. It's natural to feel that testing will slow down the development process , but once you got some unit tests for the core parts of the app, it feels awesome and the developers will have a lot of confidence in the product.
TDD speeds up development, especially when adding features. Without full test coverage, you're relying upon manual regression testing to catch bugs. Once you have actual users, that could be catastrophic to deploy broken code without even realizing it.
