Lean Six Sigma Green Belt Practitioner
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.
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.
Entry Points and Prerequisites
The main focus of this course is the application of Lean Six Sigma DMAIC methods to real life improvement projects within the delegate’s own organisation. There are two anticipated entry points to this course:
- Previous Yellow Belt training – the Green Belt course covers all of the material taught on the Yellow Belt course and serves as a refresher and then builds on the Yellow Belt knowledge. It is recommended that those who have attended the Yellow Belt course should use the methodology in their work environment before attending the Green Belt course. It is suggested a minimum of three months should be between the Yellow Belt and Green Belt courses.
- No previous training – This course also fully caters for those wishing to go straight to Green Belt level. All of the material taught at the Yellow Belt level is included in the course.
N.B. It is not a requirement to attend the Yellow Belt training before you attend the Green Belt course.
Please refer to the notes regarding your Green Belt project, see below:
Green Belt Preparation – Whilst the Yellow Belt training is intended to provide an overview of the methodology sufficient to participate as Project Contributors and undertake small improvements, Green Belts are required to lead at least one project, as part of the certification requirements. For this reason delegates are expected to bring a potential Green Belt project with them to the course. Aspects of their project will be looked at during the course. Support will be provided during the course to help delegates determine the suitability of their Lean Six Sigma project.
Delegates are also expected to bring an idea of a potential improvement to the course.
