The Lean Six Sigma certification process is designed to evaluate competencies in the following areas:
It has four steps which follow the same pattern for candidates at both Green and Black Belt level, with the latter reflecting the greater detail, complexity and application required to reach that level.
Examinations take place following training and are open book. The Green Belt exam consists of short answer, multiple choice questions focusing on concepts and simple tools of DMAIC improvement projects. The Black Belt exam is designed to test statistical and analytical skills and focuses on the use of Minitab or JMP analysis of case study data.
Following the exam, the candidate is expected to submit details of completed projects for desktop review. This is done typically by way of storyboards and associated project documentation. Lean and Green Belt candidates are expected to submit one completed DMAIC project while Black Belt candidates need to provide at least two completed projects. Master Black Belt candidates are expected to be able to demonstrate all the above as well as comprehensive implementation experience as well as training and mentoring expertise.
The candidate undergoes a 1-2 hour interview by the examiner to review the project/s submitted and to test the softer issues around leadership, change management and general understanding of Lean Six Sigma tools and concepts.
Each candidate will receive a written feedback report covering their performance across all the certification criteria. Candidates who do not pass the exam/interview process will be offered further exercises to strengthen any weaker areas.
Successful candidates receive an official BQF Lean Six Sigma Academy certificate of achievement and are added to the BQF Lean Six Sigma Certification Register.
