Why most programs fail
- Curriculum runs four to six weeks. Students burn out before they finish.
- Textbook examples feel generic. They never connect to real work.
- Mentorship ends with the class. Students get stuck on their first project.
- Certification mills sell credentials with no quality bar.
- Leadership buy in is never built into the program.

Built by someone who's been to the edge and back.
Two weeks before commissioning into the Air Force, Kevin Clay suffered a near fatal cerebral hemorrhage. He spent 29 days in a coma. Recovery took two years. The experience changed how he thought about what it really takes to finish what you start.
He founded SSDSI in 2008 to fix what he kept seeing in Six Sigma training. Programs were designed to look comprehensive. In practice, they almost guaranteed that students would quit before delivering results. Today he writes the Why They Fail book and hosts the podcast that the rest of the industry quietly references.
Read Kevin's full storySSDSI's instructors don't just teach theory. They have been in our shoes, running real improvement projects in operationally complex environments, and it shows in every session.
