# Last Planner weekly plan

## Inputs
- Last week's plan: task, crew, location, committed (yes), done (yes/no), reason if not done.
- Lookahead (next 3-6 weeks) and the constraint log, if available.

## Procedure
1. PPC = completed commitments / total commitments, as a percentage with one decimal.
2. Reasons for non-completion, one category per incomplete task: design info, materials, labor, equipment, previous work, weather, permits, client changes, planning error, other. If a reason is missing, ask for it; never guess.
3. If there is history, a Pareto of reasons for the last 4 weeks.
4. Candidate commitments: only lookahead tasks with all seven constraint types released (information, materials, labor, equipment, space, previous work, safety/permits).
5. Blocked tasks: blocking constraint, owner, date needed.

## Output
- Table A: last week (task, done, reason) + PPC.
- Table B: proposed commitments, each marked "to be confirmed by the crew leader".
- Table C: blocked tasks and constraint owners.
- Five talking points for the meeting.

## Never
- Never turn a proposal into a commitment: only the person doing the work commits.
- Never treat PPC as a productivity measure; it measures plan reliability.
