Six Sigma Quick Win Tollgate Review

A Tollgate Review will help you determine if the goals in a Quick Win Project have been completed. A Six Sigma Quick Win Tollgate Review is like a checkpoint at which the various team members meet with a project Champion and determine whether the work has been performed as indicated in the project plan and if the objectives mentioned have been achieved.


Has the “Project Charter” been developed?

(The following questions should help determine the answer)

  • Business Case: What are the compelling business reasons for embarking on this project? Is the project linked to key business goals and objectives?
  • What key business process output measure(s) will the project leverage and how?
  • What are the rough order estimates on cost savings/opportunities on this project
  • Problem Statement (Starting Line): What specifically is the problem?
  • Where does it occur?
  • When does it occur?
  • What is its extent?

Goal Statement (Finish Line)

  • What is the goal or target for the improvement team’s project?
  • Do the problem and goal statements meet the SMART criteria (specific, measurable, attainable, relevant, and time-bound)?
  • Has anyone else (internal or external to the organization) attempted to solve this problem or a similar one before? If so, what knowledge can be leveraged from these previous efforts?
  • How will the project team and the organization measure complete success for this project?

Project Scope

  • What are the physical boundaries of the scope?
  • What is in bounds and what is not?
  • How does the project manager ensure against scope creep?
  • Is the project scope manageable? What constraints exist that might impact the team?


  • When was the project start date?
  • When is the estimated completion date?
  • Is the project currently on schedule according to the plan?
  • Has a project plan with milestones been developed?
  • How will variation in the actual durations of each activity be dealt with to ensure that the expected project completion date is met?

Do we understand the Customers’ Requirements?

  • Have the customer’s been identified?
  • Has the improvement team collected the ‘voice of the customer’ (obtained feedback – qualitative and quantitative)?
  • What customer feedback methods were used to solicit their input?
  • Have the customer needs been translated into specific, measurable requirements?

Performance Baseline

  • What is the current process performance baseline?
  • How large is the gap between current performance and the customer-specified (goal) performance?

Designing the “Implementation Plan”

  • Has the team developed an implementation plan?
  • What poka-yoke or error proofing will be done to address some of the discrepancies observed in the ‘as is’ process?
  • How does the solution remove the key sources of variation discovered in the analyze phase?
  • What communications are necessary to support the implementation of the solution?
  • How will the team or the process owner(s) monitor the implementation plan to see that it is working as intended?
  • What is the team’s contingency plan for potential problems occurring in implementation?
  • How will the organization know that the solution worked?
