Lean Six Sigma Training & Certification Process
The lean six sigma certification only applies to the green belt, master black belt or black belt training courses. The following paragraphs explains how this process works :-
The process is designed to evaluate candidates competency, knowledge and skills in areas of leadership, change management, team building, project management, critical thinking, lean six sigma tools, statistical analysis and problem solving methods. The process starts with the attendance on a green or black belt training course, an examination, then the submission of one or more DMAIC projects. Although the process is the same for both green and black belt levels, any candidate who is seeking black belt status is required to submit at least two DMAIC projects. Similarly for the black belt qualification, the level of knowledge is expected to be higher than that of a green belt.
An examination generally takes place immediately after completion of the final module of green or black belt training course. The exam is open book i.e. notes, handouts from the course can be used to answer the questions. The examination consists of a combination of short answer and multiple choice questions. The questions are based on the major topics taught on the training course together with knowledge of statistical tools and the DMAIC methodology. Statistical questions help to demonstrate the candidates understanding of the use of statistical software such as Minitab or JMP [choice depends on which software was used on the course].
Following the examination candidates are required to submit projects in the form of DMAIC story boards. Green belt are required to submit just one completed DMAIC project while black belt candidates need to provide two completed projects, master black belt candidates are expected to complete at least two DMAIC projects and be able to have experience in training and mentoring on the lean six sigma methods.
The examiner will review the projects following submission and at a suitable date arrange for an interview to test the candidates knowledge on leadership, change management and other Lean Six Sigma concepts.
Successful candidates will receive a certification to the relative level of competency, unsuccessful candidates will receive a report summarizing the areas that need to be improved. If appropriate, opportunity is provided for candidates to resubmit further DMAIC projects that demonstrate the knowledge on the improvement areas.
