Lean Six Sigma for Process Improvement Projects: DMAIC Tools and Statistics – Paris, 27 Sep – 1 Oct 2027

Programme overview

Technical depth: Practitioner · Practical mode: Modelling build

Introduction

Improvement projects often stall because the problem is poorly scoped, the data cannot be trusted or the chosen solution treats a symptom rather than a verified cause. Gains that are achieved then fade within months because no control plan was put in place. This course combines Lean flow analysis with the Six Sigma DMAIC method set out in ISO 13053, and trains managers to build each statistical analysis a project needs. Participants work on datasets from several sectors and leave with a DMAIC Project Storyboard for an improvement project in their own organisation.

Course Objectives

• Select and scope an improvement project with a charter, a CTQ tree and a cost of poor quality baseline
• Validate a measurement system and establish baseline process capability and sigma level
• Verify root causes with Pareto analysis, hypothesis testing and regression rather than opinion
• Develop and test improvements using design of experiments, Pugh selection and process FMEA
• Hold the gains with control charts, a control plan and a response plan
• Build a DMAIC Project Storyboard that quantifies benefits for tollgate approval

Target Audience

• Managers leading cross-functional process improvement projects
• Process owners accountable for defect, cost or cycle-time performance
• Operational excellence and quality managers coordinating improvement portfolios
• Project managers applying structured problem solving to operational projects
• Service and shared-services managers responsible for high-volume transactional processes

Course Outline

• Benefits Quantification

Why Attend This Course

• Leave with a DMAIC Project Storyboard for a live project, tested before a mock tollgate panel
• Replace opinion-led decisions in your projects with statistical evidence sponsors can check
• Keep improvements in place after handover through control charts and clear response plans
• Work through real datasets with managers running projects in service, manufacturing and public settings

Conclusion

A process improvement project earns support when its problem is defined precisely, its causes are proven with data and its gains are held after handover. This course moves from project selection and chartering, through measurement, capability and statistical root cause analysis, to experimentation, risk analysis and statistical control. The final day applies each tool to working datasets and assembles a DMAIC Project Storyboard for every participant, so that Core Concept participants return ready to take a live project through its next tollgate.
