Most Manufacturers Implement Lean Too Early. And It Costs Them.
Most manufacturers implement Lean too early. And it costs them. If you need to improve now, do not implement Lean. When a plant is under pressure to improve, the instinct is to reach for Lean. Kaizen events. Value stream mapping. 5S blitzes. It looks like action. It feels like progress. But plants that are under pressure to improve have something in common: they always have known problems they aren't solving. And if you have problems you aren't successfully solving, the pro

How Organizations Collapse Into Firefighting
Every organization runs on 4 levels of work. Technical. Tactical. Operational. Strategic. Technical - does the work in accordance with process. Tactical - ensures the work is done in accordance with process. Operational - writes the process. Strategic - wields the entire organization. Each level has the same 3 core systems: Daily operations - do what needs to be done (planning and execution) Process improvement - learn from feedback, improve the standard. Accountability

The Error Spiral Isn't Linear. It's Exponential.
Most leaders think about errors one at a time. One mistake → one fix. Done. But that's not how it works on the plant floor or anywhere else people execute complex work under pressure. Every error you DON'T prevent creates the conditions for many more. Here's how: A team member skips a verification step. The product gets made wrong. Now you have rework. Rework eats time, disrupts the schedule, and puts people in a state of rushing. Maybe not just your facility, maybe materials

Stop Fixing Culture. Start Fixing Systems.
I keep seeing leaders throw "culture" at broken operations like it's a cure instead of a symptom. Ping-pong tables. Core values on the wall. Town halls about trust. And nothing changes. Here's the truth: you cannot build a bad organization with a great culture, and you cannot fix a bad organization by working on culture. Culture isn't a lever. It's feedback. There's an old story. The Sun and the Wind are arguing over who can get a farmer to take off his jacket. The Wind goes

Bad Accountability Beats a Good System Every Time.
Everyone in industry knows Deming's line: "A bad system beats a good person every time." It's true. Systems make success. But systems require a foundation. Without it, they don't work. We can prove this experimentally. Lean is one of the greatest system-building tools ever conceived. And it fails the vast majority of the time. The statistics are clear and supported by thousands of iterations. Why does it fail? Ask the Lean practitioners and they'll tell you: leadership. But i

The Error Spiral: Why Bad Operations Get Worse and Good Ones Get Better
And why the difference between the two always compounds Every plant manager has watched it happen. A changeover gets rushed at the start of second shift. The operator swaps the change parts but doesn't verify something critical. Maybe it's a standard that's been written down, maybe it's not. The line runs for forty minutes before someone notices there's something wrong (bottles dented, labels crooked, wrong materials, wrong print, etc). Now there's a quality hold, a financial

Bad Systems Beat Good Leaders
"A bad system will beat a good person every time." - Deming We've all seen the stats, they're clear: 70–90% of Lean, Six Sigma, and TPM implementations fail. The process excellence community's explanation: Leadership. "Superficial commitment." "Treats lean as a toolbox, not a culture." "Weak supervisors." "Doesn't give the floor a voice." The objective function is: We said do this and it didn't happen. It must be the leader's fault. But we already know that weak operational s

Why Your Leaders Aren't Failing - Your Structure Is
The Uncomfortable Truth Behind Manufacturing's Leadership Crisis Every year, companies spend billions on leadership development: executive coaches, management training, accountability systems, values workshops. Yet, in facilities across the country, the same problems continue to occur: simple repeat errors, accountability complaints, machine downtime, poor morale and unfollowed processes. Looking at the outcomes, business leaders reach the same conclusion: leadership problem.

Proactive Accountability is the Most Critical System You Don't Have
There are Three Systems Every Plant Needs and They Have to be Implemented in Order There are three core systems in every manufacturing operation. Most plants only build one of them and it's the wrong one to start with. Your first system is Accountability. It's the system that gets people to follow a process. Your second system is Continuous Improvement (CI). It's the system that makes the process your people are following better as you learn things. Your third system is Daily

Why Your Meetings Are Broken (And Why the Laws of Human Nature Predicted It)
Every organization I've ever walked into has the same meeting problem. Not too few meetings, but too many of the wrong kind. Let me give you nine laws that explain your calendar and a case for rethinking where decisions actually belong. Sayre's Law: The passion of the argument is inversely proportional to the stakes Wallace Sayre, a political scientist at Columbia University, observed that, "in any dispute the intensity of feeling is inversely proportional to the value of the

The Most Expensive Thing You Do as a Leader May Be Losing Your Temper
Many manufacturing leaders have been trained to believe that speaking with urgency communicates importance. If something matters enough, the emotions behind the correction should be visible, that a raised voice or visible frustration signals that you're serious. This is one of the most costly misconceptions in operational leadership and the damage it does is largely invisible because it never shows up on a report. Here's what actually happens when a leader delivers a correcti

Positive Accountability
There are two kinds of accountability and only one works. Negative accountability is what most companies default to. Something goes wrong. We hunt for the rule that wasn’t followed and we punish the person who did it. But here’s the uncomfortable truth: even if the rule was trained, what if nobody ever checked whether it was being followed? That employee probably deviated dozens of times before the disaster. Likely, other employees are deviating too. The inductive principle o

The True Cost of an Unknown in the Process
Hand a team a mission with no planning and everything except the desired end-state becomes an unknown. Under those conditions, Hofstadter’s Law rules: “It always takes longer than you expect, even when you take into account Hofstadter’s Law.” Every unclear step, hidden risk, surprise need, and mismatched expectation lands squarely in the gap you left, which causes performance to suffer. Leaders who issue jobs like this live in perpetual disappointment because every single job

The Irony of Lean: Why Many Implementations Fall Short
Lean is arguably one of the most powerful and comprehensive frameworks for process improvement ever developed. Yet, studies show that 70-95% of Lean initiatives fail to sustain gains, often ending up costing more than they deliver. Applying Lean without the right groundwork completed can actually hinder progress rather than help it. And without the right prerequisites in place, Lean will fail every time. How does that happen? Lean is celebrated for a reason, it’s transformati

The Power of Emotional Reflection
As leaders, we often focus on strategy, metrics, and execution, and rightfully so. That stuff is important. But what if I told you that the emotional tone you set could control your ability to drive change? Emotional Reflection: the idea that people around you will mirror the emotional state you project. And it's true. When someone acts angry at you, you will tend to feel anger. When you smile at someone, they smile back. We feel what others around us feel. Emotion is contagi

Organizations Get the Behavior They Reinforce
Picture this: It's Super Bowl Sunday The game's tied, clock's ticking, and millions of viewers are glued to their screens, hearts pounding. Stress levels? Sky-high. That's cortisol, the hormone evolved to snap us out of autopilot in high-stakes moments, surging through their bodies,. Cortisol disrupts automatic muscle and movement memories, forcing us to focus, observe, think, and decide deliberately. It's nature's way of saying, "Pay attention!” Then comes the commercial bre

Laws of Leadership: Humphrey's Law
Ever watched a Little-League team completely forget how to play baseball after the coach yells at a player? Humphrey's Law: Conscious attention to a task normally performed automatically can impair its performance, deliberate focus disrupts ingrained habits, spiking error rates. This one is essential for process leaders. People's highest performance physical capabilities occur when they run on autopilot. That's what muscle and movement memories are. Under muscle memory, peopl

Laws of Leadership: Pearson's Law
Have you noticed how much better a team's processes look on audit day? If we can run the way we're supposed to on audit day, why can't we just do it right every day? Pearson's Law: "When performance is measured, performance improves. When performance is measured and reported back, the rate of improvement accelerates." This one is critical in maintaining any systemic function of a team. If it needs to happen, someone needs to be checking. If you want that process followed dili
