    You receive IASSC-aligned courseware, practice questions mapped to the exam, mock tests, and supporting resources such as case studies and quizzes. These help you reinforce each DMAIC phase and build exam readiness.

    The programme runs for 16 hours, delivered either as two full days of eight hours or as four half-days of four hours. The schedule can flex to suit working professionals and corporate teams.

    Is there hands-on practice in the course?

    Yes. The training uses practical exercises, worked examples and case discussions so you can apply DMAIC and Lean tools to realistic scenarios, not just learn theory. This makes the concepts easier to use at work.
