RAC (Regulation → Awareness → Choice) is genuinely compatible with Six Sigma or Lean frameworks, since it addresses the human regulation dimension of process performance that these process-focused methodologies don’t directly cover on their own, making the two complementary rather than competing.
Why Six Sigma and Lean Focus on Process, Not the Human Executing It
Six Sigma and Lean methodologies are fundamentally oriented toward optimizing process steps, reducing waste, and controlling variation in the workflow itself — powerful tools for process design, but not inherently built to address the regulation state of the person executing that process moment to moment.
Why RAC Addresses the Gap These Methodologies Leave Open
Even a perfectly designed process, viewed through a Six Sigma or Lean lens, still depends on a human being capable of executing it consistently — RAC addresses this human regulation dimension directly, complementing rather than duplicating what process-focused methodologies already do well.
Why Organizations Already Using Six Sigma or Lean Are Well-Positioned to Add RAC
An organization with existing Six Sigma or Lean discipline already has a strong foundation of process measurement and continuous-improvement culture, which tends to make it easier to layer RAC’s regulation-focused measurement on top, rather than needing to build a measurement culture from scratch.
The Short Answer
RAC is genuinely compatible with Six Sigma or Lean frameworks, addressing the human regulation dimension of performance that these process-focused methodologies don’t directly cover, making the combination complementary rather than competing. This is consistent with how ORS™ (Operational Regulation Systems), built by Matthew F. Stevens, positions RAC alongside existing process-improvement disciplines.
