Lean Six Sigma Green Belt Practitioner
Programme Overview & Summary
Lean Six Sigma is a pragmatic approach that emphasises the importance of focusing on delivering what the customer wants by utilising the skills and knowledge of the employees. Improvement projects aim to reduce the cost of poor quality, increase process capability, minimise process cycle time and remove waste to deliver what the customer wants, ultimately resulting in increased customer satisfaction.
Lean Six Sigma Green Belt Practitioner provides the skills necessary to successfully complete DMAIC projects, including basic knowledge of planning, team problem-solving methods and improvement strategies.
Style and Approach
The training combines lectures with interactive group exercises and hands-on work using examples related primarily to the services industry.
Please note: This course includes a refresher of the content encountered in the Yellow Belt course. It is therefore recommended that delegates who have attended the Yellow Belt course gain several months of practical experience before returning to complete this course.
Audience
This course is suitable for all levels of professionals, contract managers, project managers, and individuals involved in minimising the process cycle time and remove waste to deliver what the customer wants, ultimately resulting in increased customer satisfaction.
Programme Structure
Through a series of workshops, delegates are exposed to a wide variety of situations to enable them to apply and practice their skills in minimising the process cycle time and remove waste to deliver what the customer wants, ultimately resulting in increased customer satisfaction.
