How to Stop Tampering with Your Processes: Lessons from Red Beads
Every continuous improvement journey inevitably faces the challenge of “tampering”: the well-intentioned but misguided tweaks to processes that, instead of solving root causes, actually make things worse. At the heart of understanding and eliminating tampering is Dr. W. Edwards Deming’s celebrated Red Bead Experiment—a hands-on demonstration that reveals why managing by results alone can sabotage quality efforts.
If you’re a quality control practitioner, a Lean Six Sigma leader, or just starting to explore the world of continuous improvement, learning from Deming’s experiment can transform the way you approach systemic change. Let’s dive into how the Red Bead Experiment highlights the pitfalls of tampering and, more crucially, how you can use its lessons to drive real, sustainable improvement in your organization.
