The Lean Growth Playbook: How Tiny Daily Improvements Can Transform an Entire Business

Most businesses don't have an ideas problem.

They have an execution problem.

Everyone can see things that are slow, frustrating, wasteful, repetitive or broken.

But instead of fixing them, people work around them.

Again.

And again.

And again.

That's how businesses gradually become complicated, expensive and frustrating to run.

The alternative is to build a culture where everyone improves something, every day.

I recently sat down with continuous improvement expert Nathan Shideler to unpack some of the most powerful Lean tools he has used throughout his career.

What became clear is that Lean doesn't need to be complicated.

You don't need hundreds of consultants.

You don't need a mountain of paperwork.

And you definitely don't need another 200-page strategy document gathering dust.

You need a few simple disciplines, repeated relentlessly.

Here are some of the biggest lessons.

1. Start With Tiny Daily Improvements

One of the foundational principles we discussed was something we teach heavily inside PBA:

TDI - Tiny Daily Improvements.

Nathan's team is only four people.

Yet they generate approximately 500-600 improvements every year.

Think about that.

That's potentially 2-3 improvements every working day from a tiny team.

Now imagine 10 people doing that.

Or 50.

Or 100.

That's where Lean becomes incredibly powerful.

You aren't relying on one brilliant CEO coming up with one massive innovation.

You're unleashing the collective intelligence of the entire team.

A small improvement might save:

• 30 seconds

• 10 steps

• One unnecessary email

• One double-handling process

• One mistake

• One frustrated customer

• One repeated question

Individually, these improvements look insignificant.

Collectively, they can transform a company.

The principle:

Don't wait for massive breakthroughs. Build a business that gets slightly better every single day.

2. Build Lean Into Your Morning Meeting

Culture doesn't come from posters on the wall.

Culture comes from what you repeatedly do.

Nathan's team uses daily meetings to reinforce continuous improvement.

A powerful morning meeting can include:

Gratitude

Start the day by recognising what's going well.

Values

Talk about what the organisation stands for and what those values look like in practice.

Learning

Share something you've learned.

Tiny Daily Improvements

Show improvements employees have made.

Problems and opportunities

Identify what needs fixing today.

You don't need an hour.

Even 10-15 minutes done consistently can completely change the rhythm of a business.

The morning meeting becomes the heartbeat of the culture.

3. Make Improvements Visible

If somebody suggests an improvement and nothing happens, eventually they stop suggesting improvements.

That's why visibility matters.

Nathan uses a very simple improvement tracker.

Ideas move through three stages:

NEW → IN PROGRESS → COMPLETED

That's it.

No complicated software required.

They originally used paper and Post-it notes before moving to reusable magnetic cards.

The tool isn't what matters.

The behaviour is.

When someone gives you an idea:

Capture it.

Review it.

Act on it quickly.

And if you can't implement it, explain why.

Never let ideas disappear into the corporate Bermuda Triangle.

Because one of the fastest ways to destroy engagement is asking employees for ideas and then ignoring them.

4. Leaders Need to Get to the Gemba

Another discipline Nathan strongly recommends is the Gemba Walk.

Gemba essentially means:

Go to where the work actually happens.

Instead of sitting in an office looking at reports about problems, go and see the process.

Nathan's team spends roughly 15-30 minutes walking the operation, talking with supervisors and employees, checking standards and identifying opportunities.

Ask questions like:

What's slowing you down?

What's frustrating?

What keeps going wrong?

What are we doing twice?

What doesn't make sense?

What could we make safer?

What could we make simpler?

What could we make faster?

Your employees are usually surrounded by improvement opportunities every day.

Leadership's job is to help uncover them.

5. Stop Guessing. Start Experimenting.

One of my favourite parts of our conversation was Toyota Kata.

Toyota Kata teaches a scientific approach to improvement.

Instead of saying:

"Here's the problem. I know the answer."

You say:

"Here's where we are. Here's where we want to get. What experiment should we run next?"

The basic questions are incredibly powerful:

1. What is the target condition?

Where are we trying to get?

2. What is the current condition?

Where are we actually?

3. What obstacles are preventing us from getting there?

What is standing in the way?

4. What is our next step?

What experiment can we run?

5. When can we check what happened?

Measure the result.

Then repeat.

This completely changes leadership.

Instead of trying to always have the answers, leaders teach people how to think.

That's far more scalable.

6. Standardise Before You Optimise

If five people perform the same job five different ways, you don't really have a process.

You have five opinions.

Lean businesses create standards.

A standard simply defines:

The best-known way we currently know how to perform the work.

Not forever.

Currently.

Because the moment somebody discovers a better way, the standard should improve.

Nathan recommends keeping SOPs visual, accessible and easy to update rather than creating massive manuals nobody reads.

The goal isn't bureaucracy.

The goal is consistency.

Once you have consistency, you can improve it.

Without a standard, you don't even know what you're improving from.

7. Training Needs a Standard Too

Creating an SOP does not mean somebody knows how to perform the task.

This is where TWI - Training Within Industry becomes powerful.

TWI Job Instruction was originally developed during World War II when organisations needed to train huge numbers of inexperienced workers quickly and effectively.

The basic philosophy is simple:

Don't just tell someone what to do.

Show them.

Break the job into:

• Major steps

• Key points

• Reasons why

Then have the learner perform the task themselves.

Then do it again.

Then explain it back.

Then follow up.

This is an important distinction:

An SOP standardises the work.

TWI standardises how you train someone to perform the work.

You need both.

Because even the world's best SOP is useless if nobody has been trained properly.

8. Leadership Is 90% Follow-Up

One line from our conversation deserves to be written on every leader's wall:

Leadership is 90% follow-up.

You can have:

Great meetings.

Great plans.

Great SOPs.

Great training.

Great ideas.

But if nobody follows up, very little changes.

The real work begins after the meeting.

Did we actually do it?

Is the standard being followed?

Did the improvement work?

Does the employee understand it?

What needs changing?

What happens next?

Businesses rarely suffer from a lack of initiatives.

They suffer from a lack of follow-through.

9. Find the Constraint Before Trying to Improve Everything

Nathan also shared a powerful example of the Theory of Constraints, popularised by Eliyahu Goldratt in The Goal.

Every business has a constraint.

Something limits the entire system.

It might be:

Production capacity.

One machine.

One employee.

Sales.

Quoting.

Recruitment.

Leadership.

Cash.

Customer service.

Until you identify the constraint, improving everything else can actually create more problems.

Nathan's workplace experienced this firsthand.

Orders were being pushed through production in large batches regardless of downstream capacity.

The result?

Work piled up.

Lead times increased.

Flow suffered.

People stayed busy...

But the business wasn't necessarily getting more productive.

By redesigning production around flow, using cells and pull systems, they achieved a remarkable improvement.

Average order completion time dropped from approximately:

44 hours → 33 hours.

That's about a 25% improvement.

At the same time, on-time delivery increased from approximately:

96% → more than 99%.

That's Lean in action.

Not people working harder.

The system working better.

10. Beware the Mother of All Waste

One of Lean's biggest enemies is overproduction.

Making things earlier than required.

Making more than required.

Starting more work than the next process can handle.

It feels productive because everyone is busy.

But the result is usually:

More inventory.

More WIP.

More handling.

More storage.

More mistakes.

More confusion.

Longer lead times.

More cash tied up.

That's why Lean focuses heavily on flow and pull.

Produce:

What is needed.

When it is needed.

In the quantity needed.

Busy is not the goal.

Flow is the goal.

11. Improve the Work Using ECRS

Another simple but extremely useful Lean framework Nathan shared comes from TWI Job Methods.

Take any process and question every step.

Ask:

Why is this necessary?

What are we doing?

Where should it happen?

When should it happen?

Who should do it?

How could we do it better?

Then apply ECRS:

Eliminate

Can we remove the step completely?

Combine

Can multiple steps become one?

Rearrange

Would changing the sequence improve flow?

Simplify

Can we make the task dramatically easier?

Do this to almost any business process and you'll find waste.

Quoting.

Invoicing.

Onboarding.

Production.

Meetings.

Sales follow-up.

Recruitment.

Customer service.

Administration.

Start questioning why things are done the way they're done.

You'll often discover the answer is:

"Because that's how we've always done it."

Which is possibly the most expensive sentence in business.

How to Start Lean Without Overcomplicating It

If your business is just beginning its Lean journey, don't try to implement everything at once.

Start here.

Step 1 - Read Two Second Lean

Paul Akers makes Lean practical, accessible and easy for teams to understand.

Read it together.

Discuss it together.

Most importantly...

Implement it together.

Step 2 - Start a Daily Morning Meeting

Keep it short.

Build gratitude, learning, values, improvements and problem solving into the daily rhythm.

Step 3 - Introduce Tiny Daily Improvements

Challenge every employee to improve something every day.

Step 4 - Track Improvements

Make ideas visible.

New.

In progress.

Completed.

Step 5 - Walk the Gemba

Leaders need to get out where the work happens.

Look.

Listen.

Ask questions.

Step 6 - Create Standards

Capture the best-known method.

Make it simple and visual.

Step 7 - Train the Standards

Don't assume people know.

Teach.

Demonstrate.

Practice.

Follow up.

Step 8 - Identify Your Biggest Constraint

Don't try to fix everything.

Find the thing restricting the entire system.

Attack that first.

Then repeat.

The Biggest Lean Mistake

There is one mistake I see business owners make repeatedly.

They start.

They get excited.

They introduce a few improvements.

Then...

They stop.

Lean isn't a project.

It isn't something you "implement" for three months.

It is a way of operating.

Some improvements will be incredible.

Some won't work.

Some employees will embrace it immediately.

Some will take longer.

There will be setbacks.

There will be frustration.

There will be moments where it feels easier to return to the old way.

Don't.

Because the real power comes from compounding.

One small improvement isn't transformational.

Thousands of improvements are.

Build a Team of Problem Solvers

Ultimately, Lean isn't really about efficiency.

It isn't even about eliminating waste.

It's about developing people.

Imagine a company where every employee comes to work thinking:

How can I improve this?

How can I make this safer?

How can I make this simpler?

How can I serve the customer better?

How can I remove waste?

How can I make tomorrow better than today?

Now multiply that thinking across your entire organisation.

That's when Lean stops being a collection of tools.

It becomes a competitive advantage.

And eventually...

Continuous improvement simply becomes the way you do business.

Don't try to change everything tomorrow.

Start with one improvement.

Then another.

Then another.

And don't stop.

Because tiny improvements, multiplied across people and compounded over time, can create massive transformation.
