自分のチーム以外で変化をもたらした経験について教えてください。

1. Frame the problem in terms leadership cares about (cost, risk, velocity)
2. Build a coalition of allied teams and sponsors
3. Start with a pilot that proves value
4. Make adoption easy — tooling, docs, support
5. Measure and broadcast the wins

S: Each team built its own auth differently — inconsistent and a security risk.
T: I wanted a shared, secure auth standard across six teams, with no authority
   over any of them.
A: I quantified the duplicated effort and risk, got a staff sponsor, piloted a
   shared library with one willing team, then ran office hours and migration
   guides for the rest.
R: Five of six teams adopted it within two quarters; a class of auth bugs
   disappeared from incident reports.
