🥣 The two ingredients for agility

✔️ Low friction: tooling and workflows that allow anyone to make changes easily. (good build systems, clean libraries, release automation, etc.)

✔️ Confidence: what we are doing is not going to break things. (CI, end-to-end testing, review, etc.)

#1 is obvious. #2 is subtle -- if we don't have confidence in the work, we will avoid it.
