The Tollgate Review and Project Closure: Handing Over Lean Six Sigma Projects

You’ve solved the problem, stabilized the data, and anchored the new behavior on the shop floor. The project feels finished. But for a Lean Six Sigma Black Belt, a project is never truly complete until it has passed the final gate. Too many brilliant initiatives slowly die a quiet death because the project leader simply walks away when the coding is done. In the Control phase, we don't just stop. We execute a formal Control Tollgate Review to officially hand over the keys to the line organization, lock in the financial savings, and celebrate the team's success so that the culture of continuous improvement keeps burning.In this project governance guide, we deconstruct the essential steps of a formal project closure. We look at the handover protocol to the process owner, documenting lessons learned, and effectively sharing wins company-wide. We also wrap up our operational case studies, showing the final results for both BlueprintRM&co and the automated aftercare system at Brummans HR Services. For education and entertainment!
