Lean and Six Sigma Project Ideas

The following is a list of Lean and Six Sigma projects to consider, based on your industry or department. Actual project case studies are also available.

Finding a project to complete your Lean and/or Six Sigma certification is a major challenge for those who take training, so hopefully this list will give you ideas to consider.

In general, consider process areas that come to mind when you think about these questions:

  • Take the longest to complete?
  • Have the most complaints?
  • Require the most employees to support?
  • Seem inconsistent month to month?
  • Have the most mistakes?
  • Have costly mistakes?
  • Seem the most hectic?
  • Have the highest risk (keep you up at night)?
  • Have legal risk or potential reputation damage?
  • Have “heroes saving the day” to meet deadlines?

Have too many projects to decide? Consider using a Project Prioritization Matrix to rank each project against many criteria.
