My criticism of this course and reason for providing only 1 star is based on the Capstone project required for completion of course. The requirement is understandably based on completion of an actual project performed for a real business but this would require a minimum of several months to complete. Many students will not have access to resources necessary to execute a project that would meaningfully demonstrate the skills learned in the Green belt courses. I suggest that Coursera creates a simulation that would require students prepare necessary documents based on a hypothetical process improvement, possibly starting from an investigation into a product deviation. Feedback could be provided at each stage of Design, Measure, Improve, and Control stages and once successful they could move on and be presented with additional materials necessary to carry the simulation forward. This would be much more useful for teaching practical application of skill and also for demonstrating ability to apply concepts.

You will have to wait months if not years to see if you pass the final project. There are still ungraded projects from 2020
