🟢 What this is: The artefact that closes the loop on any DMAIC project, rollout, or audit. Held 90 days after Control sign-off.

📦 Where it sits: Closing artefact for the Lean Six Sigma DMAIC Project Tracker (sold separately at £49). Sequence: open with DMAIC, close with PIR.

⏱ Setup time: 8 minutes. Pre-built Ardendale Bramley worked example included.

How to use this template

A DMAIC project is not closed when Control is signed off. It is closed when somebody has gone back 90 days later and answered four questions:

1. Did the interventions deliver the benefit we said they would?
2. What did we learn?
3. What did the people involved actually think?
4. What's the next iteration?

That artefact is the Post-Implementation Review (PIR). Most teams skip it. The ones that don't compound their CI capability twice as fast — every project teaches the next one.

Three rules:

1. PIR is held 90 days after Control sign-off. Long enough for realised numbers to settle, short enough that the project is still in living memory.
2. Every Improve-phase intervention gets one row in Outcomes vs Targets. Including the ones that were killed. Killed interventions are the most valuable data in the entire pack.
3. Lessons go into one of four categories. No free-form notes pages. If a lesson doesn't fit a category, the category list is wrong.

After-import setup checklist

1. Rename the workspace to your project name.
2. Open Outcomes vs Targets → add Relation to PIR Header (so outcomes link to the project they belong to).
3. Same for Lessons Learned, Stakeholder Feedback, Recommendations Forward.
4. On Outcomes vs Targets, the Realisation % formula is pre-built. Confirm it shows (Realised £ / Expected £) × 100.
5. On PIR Header, add Rollups for total expected £, total realised £, realisation rate %.
