Why They Fail!, Episode #6 – LEAN “Snake Oil”, the LEAN Only Approach
Welcome back to “Why They Fail,” the podcast that dissects the real reasons continuous improvement initiatives don’t last. In this episode, host Kevin Clay tackles a pervasive and damaging trend he calls LEAN Snake Oil. Have you been told that LEAN is the one and only answer to your business problems? Have consultants promised you a swift transformation with a few simple, data-free tools? This alluring promise of a quick fix is incredibly common, but it’s a trap that sets organizations up for failure. We’ll explore why this incomplete solution is so popular and how it cripples your ability to create lasting change.
This episode dives into the widespread fear of data that pushes leaders toward what feels easy and tangible. However, relying on gut-feel and qualitative tools alone is like operating with only half of your brain. True, sustainable improvement requires a more robust approach. Therefore, we uncover why ignoring the analytical rigor of Six Sigma is a critical mistake that leaves your improvements vulnerable to failure over time.
The Problem with a LEAN-Only Approach
A key reason that peddlers of LEAN Snake Oil are so successful is that they validate a common fear: “paralysis by analysis”. Leaders are often conditioned to make decisions based on experience and intuition. When a consultant offers a solution that avoids complex data, it feels like a relief. But this comfort comes at a high cost. As Kevin explains, LEAN and Six Sigma are like the two hemispheres of the brain; you need both to function optimally. LEAN represents the creative, hands-on “right brain,” using tools like Value Stream Mapping to visualize waste. In contrast, Six Sigma is the logical, analytical “left brain” that uses data to prove what is actually happening. To rely only on LEAN is to willingly ignore half of the equation.
For instance, consider the powerful analogy of two football kickers. One kicker is accurate, getting 100% of his kicks through the uprights. From a LEAN-only perspective, he is a total success. However, his kicks are all over the place—some barely inside the left post, others just inside the right. The second kicker also scores 100% of the time, but every single ball he kicks sails directly through the center with almost no variation. He is both accurate AND precise. Six Sigma is the toolset that allows you to see this crucial difference and build a process that is not just good, but consistently perfect and reliable under pressure.
Key Takeaways from this Podcast:
💡 A LEAN-only approach is like operating with only half a brain.
😨 Fear of data and “paralysis by analysis” drives leaders to adopt incomplete solutions.
🏈 Being accurate isn’t enough; your processes must also be precise to be reliable.
📊 Six Sigma provides the analytical tools to measure and reduce variation for precise results.
🌱 True, sustainable success requires courageously integrating both LEAN and Six Sigma.
