Author’s Note
When we talk about business mistakes, we usually imagine dramatic failures.
A major client lost.
A failed product.
A bad investment.
A disastrous hire.
Those mistakes are easy to recognize.
The expensive ones I’ve become more interested in are much quieter.
The employee you knew wasn’t right but kept too long.
The client relationship that was becoming unhealthy, but you didn’t address it.
The process that everyone knew was inefficient, but nobody took ownership of fixing.
The decision you kept postponing because it wasn’t urgent.
The exception you allowed once…
Then twice…
Until it became the standard.
These mistakes rarely create an immediate crisis.
That’s precisely what makes them dangerous.
They become expensive through accumulation.
They come from recognizing the small things we tolerated for too long.
Key Takeaways
- The most expensive mistakes often don’t look like mistakes initially.
- Delayed decisions can be more costly than wrong decisions.
- Small exceptions can gradually become bad processes.
- Keeping the wrong client, employee, or approach for too long has a compounding cost.
- Good leadership isn’t avoiding every mistake; it’s recognizing expensive patterns early.
Introduction
I’ve made plenty of mistakes in my career.
That’s inevitable.
You can’t spend more than two decades in technology and business without making decisions that, with hindsight, you’d make differently.
But something has changed in the way I think about mistakes.
Earlier in my career, I was mostly concerned about making the wrong decision.
Today, I’m equally concerned about not making a decision at all.
Because some mistakes aren’t created by what we do.
They’re created by what we continue allowing.
And those can be much harder to notice.
1. The Mistakes That Don’t Look Like Mistakes
The obvious mistakes usually get corrected quickly.
Something breaks.
Someone notices.
People investigate.
A solution is found.
The quiet mistakes are different.
Nothing breaks.
Nothing catches fire.
The business keeps moving.
But something is slowly becoming less efficient.
A little more time is wasted.
A little more frustration appears.
A little more dependency develops.
A little more margin disappears.
Nobody notices enough to stop everything and fix it.
That’s how small problems become expensive.
I’ve learned that the absence of a crisis doesn’t mean the absence of a problem.
Sometimes it simply means the problem is accumulating quietly.
2. The Cost of Delaying Difficult Decisions
There are decisions founders know they need to make.
But they keep postponing them.
A difficult client conversation.
A change in leadership.
A process that isn’t working.
A service that no longer makes sense.
A person who isn’t performing.
A partnership that isn’t delivering what was expected.
The justification is usually reasonable.
“Let’s give it another month.”
“It’s not urgent.”
“Things might improve.”
Sometimes they do.
Often, the delay simply increases the eventual cost.
I’ve learned that difficult decisions rarely become easier because we wait.
They usually become more expensive.
3. When Exceptions Become the System
This is one of the easiest traps in an organization.
A client asks for something outside the normal process.
You make an exception.
Fair enough.
Then another client asks.
Another exception.
Then someone internally says:
“But we did it for them last time.”
Suddenly, the exception has become an expectation.
Eventually, people stop knowing what the actual process is.
This happens everywhere.
Pricing.
Project scope.
Working hours.
Approvals.
Communication.
Reporting.
I’ve learned that exceptions aren’t necessarily bad.
Unexamined exceptions are.
Every exception should eventually trigger one question:
“Is this genuinely exceptional or have we discovered that our process needs to change?”
4. Keeping the Wrong Client Too Long
We’ve already talked about losing clients.
There’s another side to that story.
Sometimes the mistake isn’t losing a difficult client.
It’s keeping one for too long.
The revenue looks attractive.
So you tolerate the problems.
Constant scope changes.
Unreasonable expectations.
Delayed payments.
Excessive escalation.
Low margins.
High management overhead.
Eventually, you realize something uncomfortable.
The client wasn’t profitable.
They were simply generating revenue.
Those aren’t the same thing.
A client relationship should create value for both sides.
If one relationship consistently consumes disproportionate time, energy, and attention, the cost may be much higher than what’s visible on the invoice.
5. Keeping the Wrong Person Too Long
This may be one of the hardest responsibilities of leadership.
Hiring someone is a decision.
Keeping someone who isn’t right for the role is another decision.
And sometimes we confuse compassion with avoidance.
We give another opportunity.
Then another.
We hope circumstances will change.
Meanwhile, the cost isn’t limited to that individual’s performance.
Other people compensate.
Managers spend additional time.
Standards become inconsistent.
High performers become frustrated.
Eventually, one person’s underperformance becomes an organizational problem.
I’ve learned that being fair to one person shouldn’t mean being unfair to everyone else.
Leadership requires difficult decisions.
Sometimes sooner than we’d like.
6. The Cost of “We’ll Fix It Later”
“Later” is one of the most expensive words in business.
We’ll document it later.
We’ll automate it later.
We’ll improve the process later.
We’ll address the client issue later.
We’ll train someone else later.
Sometimes later is perfectly reasonable.
But repeated postponement creates something dangerous:
organizational debt.
Technical debt gets discussed frequently.
But businesses also accumulate operational debt.
Every workaround.
Every undocumented process.
Every founder dependency.
Every manual task.
Every unresolved issue.
Eventually, someone pays for it.
Usually at the worst possible time.
7. What Experience Changes
I don’t think experience makes you immune to mistakes.
If anything, it makes you more aware of the subtle ones.
You start recognizing patterns earlier.
A conversation feels familiar.
A client situation resembles something you’ve seen before.
A process starts showing symptoms you’ve encountered previously.
That’s one of the real benefits of experience.
Not knowing every answer.
Recognizing the warning signs sooner.
And perhaps that’s why reflection matters so much.
The goal isn’t to reach a point where you never make mistakes.
That’s impossible.
The goal is to reduce the time between:
Something doesn’t feel right.
and
We should probably do something about it.
8. Statistics
The idea that small problems become expensive when left unresolved isn’t just a founder observation. Research on organizational performance, employee turnover, and operational inefficiency shows how seemingly manageable issues can accumulate into significant costs.
Gallup estimates that low employee engagement costs the global economy approximately $8.9 trillion in lost productivity. The broader lesson is important: organizational problems that aren’t addressed don’t necessarily remain small, they can compound across an organization.

Employee turnover creates another layer of hidden cost. Work Institute’s Retention Report has consistently found that a large share of employee turnover is preventable, with career development, work-life balance, manager behavior, and compensation among the commonly cited reasons employees leave. This highlights an important leadership lesson: some turnover isn’t simply an unavoidable cost of doing business.

McKinsey’s research on organizational health similarly emphasizes that operational effectiveness isn’t created by isolated initiatives. It comes from reinforcing practices across leadership, accountability, coordination, and execution.

The exact financial impact varies enormously by company and situation.
But the principle is consistent:
Small inefficiencies become expensive when an organization normalizes them.
9. A Few Observations
After enough years in business, I’ve noticed a few patterns.
1. The problem everyone knows about is often the problem nobody owns.
Everyone sees it.
Everyone complains about it.
But nobody is responsible for fixing it.
That’s when problems become permanent.
2. Delay feels cheaper than action.
Doing nothing usually has no immediate invoice attached to it.
That’s why it’s tempting.
The cost appears later.
Often much later.
3. Exceptions are contagious.
Once people see that a rule can be bypassed, they naturally start asking why it shouldn’t apply to them.
That’s how standards slowly erode.
4. Revenue can hide bad economics.
A client can generate substantial revenue while consuming even more management attention and organizational capacity.
Revenue isn’t the same as value.
5. Experience doesn’t eliminate mistakes.
It helps you recognize familiar mistakes earlier.
That’s arguably much more valuable.
10. Frequently Asked Questions
Should every mistake be analyzed?
No
Not every mistake deserves a postmortem.
The ones worth examining are mistakes that are repeatable, expensive, or systemic.
A one-off typo isn’t a management problem.
A recurring communication failure probably is.
How do you know when to stop giving someone another chance?
There isn’t a universal number.
But repeated behavior is usually more informative than isolated incidents.
If the same problem keeps occurring despite clear expectations and support, continuing to wait may simply transfer the cost to everyone else.
Should businesses eliminate exceptions?
No
Businesses need flexibility.
The important question is whether an exception is genuinely exceptional or whether it is revealing a broken or outdated process.
Is delaying a decision always a mistake?
Absolutely not.
Some decisions benefit from patience.
The mistake is delaying without purpose.
There’s a difference between:
“We need more information before deciding.”
and:
“Let’s avoid deciding and see what happens.”
What’s the biggest lesson about business mistakes?
Probably this:
The longer a problem survives without being addressed, the more likely it becomes part of the system.
And once it’s part of the system, fixing it becomes much harder.
My Framework – The Hidden Cost Test™
Whenever something repeatedly feels inefficient, frustrating, or unnecessarily complicated, I use a simple mental test.
Ask five questions:
1. How often does this happen?
Once?
Monthly?
Every day?
Frequency matters.
2. How many people does it affect?
One person?
One team?
The entire organization?
Small problems multiply as the number of people affected increases.
3. What does it consume?
Look beyond money.
Time.
Attention.
Management bandwidth.
Employee morale.
Client trust.
All of these have a cost.
4. What happens if we do nothing for another year?
This is the question I find particularly useful.
If the answer is:
“Probably nothing.”
Fine.
But if the answer is:
“It will become much harder to fix.”
Then perhaps it shouldn’t wait.
5. Is this a one-time exception or a recurring pattern?
A one-time problem can be handled.
A recurring pattern needs a system-level solution.
The equation is simple:
Small Problem × Frequency × Time = Hidden Cost
A $50 problem isn’t necessarily expensive.
A $50 problem happening every day for five years is.
A 10-minute inefficiency isn’t necessarily important.
Ten minutes multiplied across 50 people, every working day, is a different story.
That’s why the smallest problems deserve attention when they repeat.
11. A Thought to Leave You With
The most expensive mistake may not be making the wrong decision.
It may be continuing to tolerate the wrong situation.
That’s the distinction I’ve become more conscious of with experience.
12. Closing Thoughts
I’ve made decisions in my career that I would make differently today.
I’m sure I’ll make more.
That’s part of building anything over a long period of time.
But I no longer believe the objective is to eliminate mistakes.
That’s impossible.
The better objective is to shorten the lifespan of bad decisions.
Recognize them.
Talk about them.
Correct them.
Learn from them.
Move forward.
Because a mistake becomes much more expensive when we spend months or years pretending it isn’t one.
The client you know isn’t right.
The employee who isn’t working out.
The process everyone hates.
The decision nobody wants to make.
The workaround that was supposed to be temporary.
These things rarely announce themselves as major problems.
They simply become normal.
And that’s where the real danger lies.
Normal doesn’t always mean healthy.
Sometimes it simply means we’ve been living with the problem for long enough.
After more than two decades in IT and business, that’s one lesson I wish I’d understood earlier:
Don’t only look for the mistakes you’re making.
Look for the problems you’ve become comfortable tolerating.
Those might be costing you the most.

My Principle
Don’t measure the cost of a problem by how small it looks today. Measure it by how long you’re willing to let it remain.
Because some of the most expensive mistakes in business don’t arrive as disasters.
They arrive as “we’ll deal with it later.”
And later has a habit of becoming very expensive.
