The Lean Six Sigma Black Belt Project

This certificate is underpinned by a course-long project. The project allows students to directly apply their learning and use their course time to address an issue relevant to their organization. They can choose to follow a Lean track or a Six Sigma track.

Projects can be conducted either for a learner’s current employer or for a nonprofit organization with which the learner has a close association. Instructors work with each learner to identify a suitable project and assist with advice and troubleshooting throughout. Learners can even consult with a program advisor before enrolling in the Black Belt course to brainstorm and select the best project for their needs.

Learners should plan to spend about 15 hours per week on this course, which includes time spent on the final project. Weekly assignments are directly connected to and will contribute to the project deliverables.

Schedule and Time Commitment

The 100% online Lean Six Sigma Black Belt certificate spans 16 weeks. It includes pre-work, weekly learning modules and breaks. The breaks provide students with additional time to collect data, present gate reviews to management teams at their organization and prepare assignments.

Students have the opportunity to participate in online discussions with classmates about their project deliverables and receive real-time coaching from the instructor via live WebEx sessions, a discussion forum, email or phone call.

Students who successfully complete the course typically devote 95 hours of study during the 16 weeks of learning modules. Instructors recommend planning on spending six to 10 hours each week on learning activities.

The online format enables students to do their coursework when and where they want, but there are weekly reading assignments, project deliverables and quizzes that must be completed on schedule.
