🧠 Lean Neuroscience A Lean Perspective on Change Management Part 2

Part 2 | Can New Procedures Really Overcome Old Habits?

In Part 1, we explored why many Lean transformations don't last.
The processes change.
But the habits behind them often don't.

But this raises another question:

Are people really resisting change?

Or is there another mechanism at work that we often overlook?

Think about the first time you drove a car.

Clutch.

Gear.

Mirrors.

Turn signal.

Steering wheel.

Every movement required conscious attention.

You were probably focused entirely on the act of driving.

Now think about driving the same route today.

Sometimes, you arrive at your destination and realize you barely remember the journey.

You haven't forgotten how to drive.

Quite the opposite.

Your brain has learned how to do it without requiring your full attention.

And something very similar happens on the shop floor.

When Work Becomes Automatic

An operator may perform the same task hundreds, sometimes thousands of times using the same method.

Over time, they no longer think consciously about every movement.

They don't need to.

The behavior has moved from being a conscious decision to becoming a habit.

This is one of the reasons changing a work process can be much harder than simply changing a procedure.

The procedure may change overnight.

The behavior behind it doesn't.

Charles Duhigg, in The Power of Habit, describes habit formation through a simple three-part loop:

Cue → Routine → Reward

A cue triggers a behavior.

The behavior is repeated.

And the resulting reward reinforces the pattern.

As this loop is repeated, the brain becomes increasingly efficient at performing the behavior.

Why?

Because one of the brain's fundamental priorities is efficiency.

It doesn't want us to consciously process every single action we take.

If something happens repeatedly, the brain looks for ways to make that behavior easier and more automatic.

And this is precisely where Lean transformation encounters an interesting challenge.

When the Standard Changes

Imagine an operator who has been working with the same method for years.

A new Standard Work instruction is introduced.

The operator learns the new method.

Perhaps the first day goes perfectly.

The second day too.

But then production pressure increases.

A machine problem occurs.

An urgent order arrives.

The operator has to respond to something unexpected.

Or attention simply needs to move somewhere else.

And without consciously deciding to do so, the operator may return to the old method.

Why?

Not necessarily because they don't want to change.

Not necessarily because they disagree with the new standard.

And not necessarily because they don't understand it.

Sometimes, the brain is simply choosing the path it knows best.

The old behavior has been repeated hundreds or thousands of times.

The new behavior hasn't.

That difference matters.

A Different Way to Think About Change

A new procedure can be technically correct.

A new process can be more efficient.

People can even be trained.

But none of these automatically changes behavior.

When we ask people to work differently, we are asking them to replace a familiar pattern with a new one.

And that is not simply a process change.

It is a behavior change.

This is where Lean thinking and Change Management intersect.

Lean helps us improve the work.

Change Management helps people move through the transition.

Lean Neuroscience looks more closely at what happens between the two.

From Process Change to Behavior Change

Imagine a company introducing a daily Kaizen routine.

The meeting is scheduled.

The board is prepared.

The format is standardized.

Everyone receives training.

For the first few weeks, participation is high.

Then production pressure increases.

The meeting becomes shorter.

Some people stop attending.

The board is updated less frequently.

Eventually, the old routine begins to return.

Was the Kaizen system poorly designed?

Maybe.

But there is another question worth asking:

Did the new behavior have enough repetition, reinforcement, and support to become part of the team's routine?

This distinction matters.

A transformation is not complete simply because people understand the new process.

It is not even complete because they successfully follow it for a few weeks.

The deeper change happens when the new behavior becomes increasingly natural.

When people no longer need to consciously remind themselves to do it.

When the new way becomes:

“This is how we work.”

That is the point at which process change begins to become behavior change.

The Advantage of Old Habits

Our existing habits have one enormous advantage:

They already exist.

We don't have to remember them.

We don't have to consciously decide to perform them.

We don't need someone standing beside us reminding us what to do.

They have been repeated so many times that they have become part of our normal way of working.

This is why introducing a new standard can be much easier than sustaining it.

The new standard is competing with an existing behavioral pattern.

And that pattern may have years of repetition behind it.

This changes the way we should think about Lean transformation.

Instead of asking only:

“How do we introduce the new process?”

we should also ask:

“How do we help the new behavior become the new habit?”

That is a very different question.

And perhaps it is the question that determines whether a Lean transformation becomes permanent — or simply becomes another initiative people remember having tried.

A Different Way to Look at Lean Transformation

This is the starting point for the Lean Neuroscience series.

In the coming articles, we will explore the relationship between:

Habits → Behavior → Learning → Lean Transformation

First, we will look at how habits are formed.

Then, we will explore how the brain learns new behaviors and how this knowledge can be connected to behavioral change in Lean transformations.

Later, we will examine how repeated behaviors become routines, how routines influence organizational culture, and how Toyota Kata can be understood not simply as a problem-solving method, but as a routine for learning.

The goal isn't to turn Lean practitioners into neuroscientists.

It is much more practical than that.

It is about understanding why some Lean practices become part of everyday work...

while others slowly disappear.

Because if we want Lean transformation to last, changing the process is only part of the work.

We also need to understand the people who perform it.

🎯 Lean Insight

A procedure can change overnight. A habit is built through repetition.

If we want Lean transformations to last, changing the process is only the beginning.

We also need to create the conditions in which the new behavior can be repeated until it becomes the new normal.

What Have You Seen at Your Gemba?

When a new procedure or Standard Work is introduced, what do you think is the bigger challenge?

Understanding the new method?

Or letting go of the old one?

I'd be interested to hear what you have observed in your own workplace.

About the Lean Neuroscience Series

Lean Neuroscience explores Lean transformation through the lens of human behavior, habit formation, learning, and neuroscience.

Because a Lean transformation is ultimately not only about changing processes.

It is about changing the way people think, learn, and work.
