Lean Six Sigma Tools and Concepts

Lean Six Sigma is not just one methodology, one tool, or one narrow concept. Lean Six Sigma is a blending of critical thinking, observation, investigation, measurement, analysis, and systematic application of multiple skills, tools, and concepts.

The application of a Process Improvement Model is captured in the DMAIC methodology - Define, Measure, Analyze, Improve and Control. Each phase of the methodology uses various tools and concepts to clearly identify the criteria needed to address the Problem Statement (the foundation of an improvement project).

Below is a list of some of the tools used in Lean Six Sigma and introduced in the Lean Six Sigma Professional Development Training and Certifications offered by WNE and its partners.
