02 / Approach

Embed early, ship calmly,
leave the team better than we found it.

We work as if we'll still be on the team in a year — because we usually are. The first three weeks set the next six months.

  1. Calibrate. Read the room, the metrics, the open tickets.
  2. Pick the one thing. Write the spec. Get sign-off in days, not weeks.
  3. Ship the thinnest version. Watch what users actually do.
  4. Iterate. Hand the operating model to the team.

“They wrote the spec, ran the standup, and shipped the thing. Three weeks in, our team had stopped thinking of them as a contractor.”
