Improve tollgate and pilot exercise

Learning objectives

• Explain the purpose of improve tollgate and pilot exercise in a garment-factory improvement project.
• Apply the described method to a representative shop-floor situation.
• Recognize the common mistakes and how to avoid them.

Concept

The Improve tollgate confirms selected solutions address verified causes, have demonstrated results, acceptable risk, and a credible implementation plan.

Required evidence: idea log, CTQ gates, selection matrix, solution FMEA, DOE/pilot protocol, raw data, effect and CI, guardrails, cost-benefit, future state, implementation plan, and Control inputs.

Gate questions test representativeness, practical importance, risk reduction, readiness, and Control handoff.

Garment-factory example

A sewing-line pilot changes needle replacement, machine setup verification, and first-piece controls to reduce seam damage; the tollgate reviews all evidence before rollout.

Method

1. Compile evidence pack.
2. Independent review.
3. Sponsor and process-owner attendance.
4. Approve rollout or request rework with due date.
5. Transfer artefacts to Control.

Common mistakes

• Scaling from an uncontrolled trial.
• Hiding pilot deviations.
• Claiming benefits before finance validation.
