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.

Lean management teaches that standards are the foundation of safety, quality, and improvement. In aviation, those standards take the form of checklists, redundancies, procedures, and strict cockpit protocols designed to prevent human error.

In this episode, we examine the tragic aircraft accident that claimed the life of Greg Biffle and his family, and what it reveals about the danger of ignoring established standards. Reports indicate that critical procedures were bypassed—checklists weren't followed, and an unqualified individual was allowed into the cockpit. In aviation, such deviations can quickly turn routine operations into a catastrophe.

Lean organizations understand this principle deeply. Standard work exists not to restrict people, but to protect them. It ensures that critical steps are followed every time, preventing variation that can lead to defects, injuries, or worse.

This episode explores how aviation and Lean thinking share the same core truth:

Standards are written from experience, and ignoring them removes the safeguards that keep systems safe.

Whether in manufacturing, healthcare, aviation, or leadership, the lesson is clear—discipline in following standard work is what makes improvement possible and prevents tragedy.

Mark DeLuzio, the Father of Lean Accounting, tells his experience and observations on how traditional cost accounting will derail a Lean Transformation.

In many organizations, Lean transformations don't fail on the shop floor—they fail in the finance office. In this episode, "The CFO vs. Lean: The Fight That Gets Lean Leaders Fired," we examine a pattern that plays out in companies across industries: Lean improvements begin to transform operations, but traditional cost accounting systems tell leadership the exact opposite story.

As inventory falls, batch sizes shrink, and flow improves, the accounting system often reports declining "efficiency," higher unit costs, or unfavorable absorption variances. The numbers appear to signal failure—even when operational performance is clearly improving. When executives rely on these metrics, the Lean initiative becomes the scapegoat. Too often, the Lean leader is blamed for results that are actually caused by outdated financial measurement systems.

In this episode, we unpack the structural conflict between Lean principles and traditional cost accounting, explore why CFOs frequently defend these legacy systems, and explain how perfectly "correct" financial reports can lead companies to make deeply wrong decisions. Most importantly, we discuss how organizations can realign finance with Lean thinking so the transformation—and the people leading it—don't become casualties of the numbers.

In this episode, you'll be able to take away why many "logical" workplace measures and incentives can drive behavior that conflicts with Lean principles, and why comparing work decisions to everyday home-life decisions can make Lean concepts easier to understand and teach.

You will hear about various examples, including grocery shopping and volume discounts, which highlight purchase price variance and excess inventory. You will explore the concepts of push versus pull using the supermarket and kanban approach. You'll gain insights into utilization and overall equipment effectiveness (OEE) and understand how "banking" uptime can lead to overproduction and unmet demand.

Additionally, you will investigate changeover strategies using a multi-part thermoforming case, illustrated through a barbecue analogy comparing hot dogs and hamburgers. Finally, you will discover why oil leaks and poor visual management are perceived differently in the workplace compared to a car context, including the use of dashboards, warning lights, signs, and scoreboards.

A shop floor comment stops everyone in their tracks: the work finally matches what the customer actually needs. That is the spark behind Accidentally Aligned, and it opens a bigger issue most leaders dodge: alignment does not come from posters, audits, or a new playbook. It comes from how leaders behave when the process is broken, and the numbers are ugly.

Mark and today's guest, Jason Neal, get into the messy middle of transformation: earning trust at the Gemba, protecting dignity when tempers flare, and dealing with the damage caused by "Lean policing." They also tackle a practical trap that shows up everywhere: leaders say they want engagement, then they take away overtime without replacing it with a better system. The result is predictable. So is the fix.

If you are trying to keep momentum after the first wave of kaizen, this episode gives you language and moves you can use on Monday morning.

Most Lean efforts do not stall because people hate improvement. They stall because the system was never built to support it.

This episode gives you a fast, practical lens for evaluating whether your organization is built to sustain improvement. You will learn how to recognize common traps that keep Lean efforts stuck, why certain measurement habits create the wrong behavior, and how to distinguish capability building from project theater.

By the end, you will have a sharper way to assess your structure, roles, support functions, and operating rhythm, so you can stop guessing and start fixing what is really holding you back.
