Why study this course

The IASSC Certified Lean Six Sigma Black Belt™ (ICBB™) is for professionals who are involved in complex improvement projects and require a expert level of understanding of all aspects of the Lean Six Sigma Method and demonstrate a high level of competency in the phases of Define, Measure, Analyse, Improve and Control (DMAIC) as defined by the IASSC Lean Six Sigma Body of Knowledge™.

The Lean Six Sigma (LSS) certifications are designed to support organisations in their mission to improve customer satisfaction, boost performance levels, and shorten the time-to-market. Professionals and consultants will benefit from LSS's potential for cross-industry application and increased salary.

Holding a Lean Six Sigma Black Belt shows an understanding on how to implement, perform, interpret, and apply Lean Six Sigma at an advanced level of proficiency.


This course pricing includes a voucher for the IASSC Certified Lean Six Sigma Black Belt Exam, which is an online proctored exam through PeopleCert.

The exam is:

  • Four hours (240 minutes) duration

  • 150 questions (multiple choice and true or false)

  • Pass mark is 105 out of 150 (i.e. 70%)

  • Closed book

After passing the exam, each student’s certificate will be made available to them via PeopleCert.

It is highly recommended that you spend some time each evening of this course reviewing and consolidating what you’ve learned, to be well prepared for the exam.
