Planning a phased rollout

Big-bang migrations fail loudly. Phased rollouts fail small — and teach you things.

The sequence

Start with low-risk, high-visibility apps. Prove the pattern, collect feedback, then move each next group. Keep the old path alive until the new one is boring — boring is the goal.

How long between phases?

Long enough to see a full work cycle — usually one to two weeks — and short enough that momentum survives.

Frequently asked questions

Who should be in the first phase?

A friendly team with a real workload: friendly enough to tolerate friction, real enough to expose problems.
