The Cheapest Patch Is the Most Expensive Fix

Skipped preventive maintenance, cheap patches, and “someone checking” in place of process control. After decades of finishing turnarounds, I’ve come to believe the problem isn’t the equipment, and it isn’t a single manager. It’s the culture.

I’ve been in many hundreds of factories on multiple continents over the last 40 years, but one stands out.

The first walk-through told me everything. The equipment was good, in fact beautiful. Somebody had specified it well and paid for it. Then, somewhere along the way, the organization stopped treating it as the thing that makes the money.

I’ve never, before or since, seen so much oil in an alkaline cleaning bath. Every sensor had been abandoned in place. People were checking things by hand, but not the right things. Nothing was maintained; when something broke, or when no one understood how it worked, it was disconnected and the task was performed manually. I was engaged to solve massive adhesion failures, and the root cause was obvious right away. It didn’t end with pretreatment. Nearly all of the automation was disabled, and the chemical supplier hadn’t visited in more than a year.

I have led turnarounds in finishing operations for most of my career, and I keep seeing the same sequence. Preventive maintenance (PM) gets skipped. The cheapest patch gets approved to keep product moving. Automated controls and good instrumentation are abandoned in place and replaced with “someone checking,” manual process control, and no recorded key performance indicators (KPIs). The end state is predictable: extended downtime, warranty returns, and unhappy customers. In the worst cases, it means injuries from neglected equipment and even fatalities.

The Band-Aid isn’t the enemy

Let me be clear about one thing: the Band-Aid has its place. Short-term countermeasures stop the bleeding, and when there’s a fire, being a first-rate firefighter is job number one.

The trouble starts when the Band-Aid becomes the strategy. In a powder line, that looks like:

• Chasing orange peel, pinholes, or poor adhesion at the booth, gun by gun, while the real driver sits upstream in washer chemistry, rinse quality, or dry-off.
• Bumping oven setpoints to compensate for a part load the oven was never designed for, instead of profiling the part and verifying the cure.
• Absorbing rework and scrap week after week rather than investing in first-pass yield (FPY).
• Running equipment in ways it was never designed to be used.

The problem returns, usually with worse symptoms. The machinery and the process are the moneymakers, yet they get treated as the cost burden.

The better starting point is design intent, after any glaring safety issues. Compare it with how the equipment is actually used. Once the gap is identified, closing it is CapEx invested wisely.

When I first started thinking about this, I was focused on root-cause problem solving and the many ways processes go off the rails. Then it occurred to me that I was looking at a cultural problem. That culture almost always comes with the same leadership characteristics, and it consistently trades long-term health for short-term problem solving.

What I see in these plants:

• Bad operating metrics, or none at all. What gets measured gets done. If you are measuring the wrong things, you drive the wrong behavior.
• Thin process knowledge, which leaves improvement to people focused on symptoms and day-to-day problems.
• No real value placed on best-in-class practices as part of the culture, and “good enough” (the 80/20 rule) used as an excuse.

My blind spot

In a way, I’m a victim of my own good fortune. I have worked in organizations where Lean Six Sigma, total productive maintenance (TPM), Kaizen, and advanced product quality planning (APQP) were highly valued. I received an enormous amount of training and mentorship (I stand on the shoulders of giants), and I trained others, implemented the methods, failed, and tried again until it worked. My maintenance budgets and capital spending went up. So did my overall equipment effectiveness (OEE), while time through process and work in process (WIP) dropped dramatically. We delivered one-day WIP directly to assembly and cut department working hours: no more overtime, and headcount dropped through attrition.

The side effect is that I have no other way to look at it. My values were formed by those people and experiences, so it is hard for me to see the “just get by” perspective. It’s easy to assume everyone has the same tools and values, and that they’re just common sense. They aren’t.

I also refuse to believe this is simply good managers versus bad ones. This culture rarely exists in excellent organizations, though even mature, operationally excellent companies have plants that lag behind. Those plants ship product and hit their numbers until the neglect becomes painful enough that someone calls for help. Even then, changing the culture can be excruciating. Recovery is hard in a practical sense, too: you can’t capture the rewards of one improvement while the rest of the process is broken.

Where to start

If you know better but can’t get traction, or you’re in the middle of your own recovery and need some wins, the good news is that the tools already exist. Lean Six Sigma and Kaizen work even in plants with no sophisticated quality department and no written quality manual reflecting the voice of the customer.

1. Collect data. Data is the foundation. Build a simple Pareto chart, identify your critical equipment, and track downtime. For a powder line, that usually means the conveyor, the oven, the washer, and the booth and recovery system. Many plants don’t track safety well, but days since the last lost-time accident is a black-and-white measure. Use old records alongside current numbers, and keep it simple. Every process is different; my typical focus is on FPY and a Pareto of defects to show where to spend the money.
2. Launch a continuous improvement initiative. Involve everyone on the plant floor, starting with 5S and a weekly or every-other-week walk-through. Require plant leadership to attend on a regular schedule.
3. Find measurable wins. This is where every turnaround gets its footing. Choose metrics that matter: quality, days of WIP, safety, and uptime. Early wins are where culture change begins, because teams start to feel like they’re winning again.
4. Train everyone with one voice. I can’t imagine success without training and education. The main purpose of a training program is to tell everyone the same thing about what the organization values.
5. Build a “5 Whys” culture. This is hard. People hesitate to offer improvement ideas if they expect them to be shot down as “Band-Aids,” yet mentoring through the 5 Whys is what creates real ownership of corrective actions. Engagement gives people agency in their own workspace. Build a culture that responds with a quick fix when necessary but never leaves it in place. Every problem calls for a root-cause determination and a follow-up plan to fix it at the source.
6. Prepare for the star performer. Often the plant’s best firefighter becomes the first obstacle. Remember that change can threaten their identity, which is hard for anyone. I have personally watched individuals sabotage initiatives, even corrective actions. I have also seen the other outcomes: when you make such a person your ally, they become dedicated to your success and the team’s. Sometimes they change once they get a few wins of their own. More often, the culture doesn’t change until the person changes or moves on, and then the wins begin.

It was a long road for that plant. Even the basics, replacing the broken sensors and dumping and recharging the washer, took a cultural shift. Sustaining the repairs and improvements took longer still, and it would have been impossible without the change in culture. In the end, the investment in PMs and improved operating practices paid off in higher quality and lower inventory.

Closing thought: The equipment is rarely the real root cause. Culture decides whether a plant treats its line as the engine of the business or a line item to be squeezed, and culture changes when people start winning.
