Lean 911

A CNC machine crashed on the shop floor. Nathan Corliss walked out as a young supervisor, angry and ready to blame the operator.

What happened next became one of the most important leadership lessons of his career.

Mark DeLuzio and Nathan talk about the moment that forced Nathan to confront his own behavior as a leader, and how the scars on his knuckles became a permanent reminder to pause, reflect, and lead differently. The conversation centers on hansei, the Lean practice of honest self-reflection, and why it matters when pressure is high, mistakes are visible, and people are watching how leaders respond.

You'll hear how one shop floor incident connects to emotional intelligence, respect for people, Kaizen report-outs, after-action reviews, standard work, compliance, and the danger of fear-based leadership.

For Lean leaders, CI managers, plant managers, and executives, this episode is a practical reminder that culture is shaped in the moments when things go wrong. The real test is not whether leaders know the right Lean language. It is whether they can own their mistakes, protect trust, and help people improve without shutting them down.

This is an unedited replay of a previous Lean 911 episode, originally published on January 13, 2023. We're bringing it back because the issue still causes Lean transformations to stall, drift, or flatline.

One of the most misunderstood parts of Lean, Standard Work, is often dismissed as unnecessary. So many companies contend that they are "doing" Lean, but leave Standard Work by the wayside. In this episode, you'll learn the answers to the most perplexing questions, notions, and beliefs regarding Standard Work, which is a key component of the Toyota Production System.

In this episode, we dive into the rise, dominance, and controversy surrounding Six Sigma — the corporate improvement system that promised near-perfect quality and became a management obsession across America. From Motorola's statistical revolution to Jack Welch's aggressive rollout at General Electric, Six Sigma evolved from a useful quality tool into what some critics call a full-blown corporate ideology.

Drawing from Mark DeLuzio's provocative essay "The Six Sigma Hysteria," we explore why many Lean practitioners believed Six Sigma created more bureaucracy than breakthrough innovation. We unpack the clash between Lean thinking and Six Sigma methodology, the explosion of belt certifications and consulting culture, and the argument that companies became obsessed with measuring defects while ignoring waste, flow, and human creativity.

Along the way, we examine real-world stories from Toyota, Danaher, and GE, and from factory floors where frontline employees solved problems that data alone could not. We also ask a bigger question: Are modern businesses repeating the same mistake today with AI, Agile, and productivity frameworks?

This episode is about more than Six Sigma. It's about the danger of turning tools into religion — and what happens when companies mistake methodology for culture.

Manufacturing Engineers pride themselves on precision, but what if the biggest waste is hiding in plain sight—inside the equipment itself?

In this episode, we challenge the status quo: excess feeds, slow speeds, and bloated cycle times that no one questions. Even worse, capital equipment is often purchased without alignment to Lean principles—locking in inefficiency for years. Learn how to look at Capital Equipment from a Lean lens…you will find out that equipment vendors are not your friend!

We’ll break down how this happens, why it persists, and what engineers should be doing instead. If your machines are running, but not improving, this episode is for you.

In this powerful episode of Lean 911, Mark DeLuzio sits down with former Air Force fighter pilot and Danaher sales leader Randy Fitzhugh to unpack the real science behind value selling and why most organizations get it wrong.

Drawing from his elite military background and executive experience, Randy reveals how sales is a disciplined, repeatable process. Together, they break down the four pillars of value selling: qualifying opportunities, monetizing value, pre-call planning, and time & territory management.

You'll hear eye-opening stories, from cockpit checklists to multimillion-dollar deals, that show why process, preparation, and deep customer understanding outperform charisma every time.

This episode dives into:

Why most sales teams think they sell value but actually don't

How to monetize quality, delivery, and lead-time improvements

The hidden cost of treating products like commodities

Why checklists (yes, like pilots use) can transform your sales performance

How small improvements in sales activity can drive massive revenue gains

The critical role of lean thinking in commercial excellence

"You don't get what you expect. You get what you inspect."

Stop selling features. Start selling value, systematically.
