Before the session

Read Days 31, 34 and 37 (about five minutes each), or Module 4 on the cheat sheet.

The 30 minutes

  1. 0–5 minOpen

    Quick round: name one piece of our work that turned out bigger than we thought.

  2. 5–15 minDiscuss three days
  3. 15–25 minExercise: Slice it thin

    Pick the biggest item in the backlog. Split it by path, channel, data type or rule until the first slice is small and usable end to end. Cross out any slice that is just one technical layer.

  4. 25–30 minAction for the week

    Each person writes down what done means to them, in five lines or fewer.

    Agree the team rule: “Done means usable. Written down. Every time.”

Watch for

Splitting by technical layer (Day 34). If a slice gives a user nothing on its own, slice again.

You’ll need

The backlog, a whiteboard or shared doc, and a timer.

Next session: Module 5 · Estimation & forecasting. Bring each person's five-line definition of done.
