Lean Six Sigma is a pragmatic approach, which emphasises the critical importance of focusing on delivering what the customer wants. To achieve this Lean Six Sigma participants will learn how to engage with the customer and utilising the Lean Six Sigma skill set produce a much-improved to-be process.
This course focuses on the Define-Measure-Analyse-Improve-Control i.e. DMAIC aspects of Lean Six Sigma and continuous improvement projects. The aim is to reduce the cost of poor quality, increase process capability, minimise process cycle time and remove waste to deliver what the customer wants in the most efficient way possible - given the changing conditions in which processes operate. Ultimately resulting in increased customer satisfaction, whether this is for internally focused customers (for example HR, Finance, Procurement, Operations or others) or external ‘paying’ customers.

This course also includes content to enable participants to consider how teams work and perform in the Lean Six Sigma environment with a consideration of some concepts of organisational change management.

The course is aimed at general continuous improvement practitioners in either a service or manufacturing domain. However, the statistical content has been reduced as Statistical Process Control (SPC) in now seen as a more in-depth skill, and beyond what most Green Belt practitioners require on a day-to-day basis. A further bridging course covering SPC is offered on the journey to becoming a Lean Six Sigma Black Belt.
