Sometime in the next few weeks, your leadership team is going to agree on a 2027 margin number.
It’ll be up. Maybe a point, maybe three. Someone will build the bridge to get there: a little price, a little volume, and a cost target that gets handed to every plant with a date next to it.
Then somebody should ask one simple question. Which line, in which plant, is that margin coming from?
Ask it and watch the room. You’ll hear plenty about initiatives. You’ll hear very little about lines.
The plan is the easy part
Most manufacturing margin improvement plans get built from the top down. Price is hard to move right now, and volume isn’t entirely yours to control. That leaves cost, and cost lives on the floor, which is the one place the plan never visits. It’s a lot more comfortable to debate a price increase in a conference room than to stand next to the line that makes the product.
The floor doesn’t send you a bill, either. A changeover that takes four hours when it should take one shows up as a variance. Scrap sits inside standard cost, where it’s been quietly accepted for years. A pile of safety stock looks like good judgment. None of it is a line item, so none of it has an owner.
A decent year makes this worse. When orders are coming in and the numbers look fine, average becomes the target and nobody goes looking.
Manufacturing Margin Improvement: Five places it hides
Start with capacity.
We worked with an industrial products manufacturer that was completely sold out and running 24/7. Overtime was maxed. Everyone assumed the answer was another line. But OEE was sitting near 50 percent, which means that for half the time the line could have been making product, it wasn’t. We went after changeovers, scrap and the way the plant was managed day to day. Within three months they’d found between $743,000 and $1.7 million in benefits. No new equipment.
Lead time comes next.
And it gets treated like a customer service metric when it’s really a cost. Every day a product spends waiting turns into inventory, and then into expediting and overtime once the order finally gets urgent. A construction equipment maker we worked with cut lead times by 60 to 75 percent. Their lead times improved enough that they stopped buying fabrication and welding outside and brought the work in-house.
Then there’s scrap.
Three percent sounds like a rounding error until you multiply it by your sales. At $50 million, that’s $1.5 million of product you made and threw away, if you count it at selling price. Count it at cost and the number shrinks, but it’s still real money, and it doesn’t come with a capital request. A window manufacturer, working alongside its glass supplier, took broken glass from 3 percent to 0.3 percent. That was worth $2 million a year.
Suppliers: You Pay for Their Problems.
Purchasing grades suppliers on delivery, and operations pays for the bad ones in safety stock, rushed freight and a line waiting on parts. The cost never gets added up in one place. In that same glass story, inventory on hand went from 17 days to 6 hours, and the plant got back more than 25,000 square feet. Scorecards didn’t do that. People working on the supplier’s floor did.
And equipment.
When the machine that sets your pace goes down, you don’t just lose repair dollars. You lose sales capacity. Yet maintenance usually sits in a budget line nowhere near margin. A diversified manufacturer with 75 plants went after OEE and total productive maintenance, rolled out in tiers, and EBITDA rose 30 percent in three years.
These five aren’t separate problems. Equipment that stops eats capacity. Scrap steals the hours that capacity needed. Slow lead times pile up inventory that hides supplier trouble. Pull one thread and the others move.
January is too late
Here’s what the calendar looks like. Our diagnostics typically take two to three weeks. Start in November and you have findings in December, while the 2027 number can still change. You start fixing in the first quarter and you see it in the second.
Start in January and the story runs differently. You write the budget on hope, discover the gaps in March, fix them over the summer, and explain the miss in the fall. The calendar doesn’t care how good your intentions were.
One industrial manufacturer we worked with found $1.5 million in operating cost reduction in 12 months, through productivity, scrap and supply chain work. Most of it sat in places their P&L had never shown them.
What I’d do this month
If I were in your chair, I’d do three things before that number gets locked.
- Walk the floor yourself with one question: where are we losing money here, in dollars? Not “how’s throughput.” Not “what’s the OEE.” Dollars.
- Then pick the line that sets your output and get an honest loss tree on it. Breakdowns, minor stops, slow running, startup scrap. All of it.
- Finally, get scrap rate, lead time, supplier on-time delivery and unplanned downtime onto a single page, ranked in dollars instead of percentages. Dollars end arguments. Percentages start them.
Then ask your team three things and notice how long the answers take.
- What’s our real OEE on the line that sets our pace?
- What does our scrap cost us in margin?
- Which supplier problem are we paying for in inventory right now?
If the answers take a week and three spreadsheets, you’ve found your first gap.
You can do all of this yourselves, and some of you will. But the room usually has a hard time saying out loud what the floor already knows. That’s where we come in. We’ll start with a 30-minute call. If we see the opportunity together, we’ll spend a day on your floor at no cost, without disrupting production, and give you a quantified estimate of what’s there.
If we’re wrong, you’ve lost a day. If we’re right, you found out in November instead of next September – and significantly improved your margin along the way.
The margin is on your floor right now. It’s time to find it. Schedule your 30-minute manufacturing margin review with me to get started.
