Why Outdated Specs Are the Real Quality Risk: Lessons from thyssenkrupp elevators, Materials, and Boundaries

The biggest quality risk is not poor workmanship. It's outdated specifications. I'm a quality and brand compliance manager at an engineering company, and I review roughly 200 unique deliverables each year before they reach customers. In Q1 2024, I rejected 12% of first deliveries. The reason wasn't sloppy labor. It was that the specs we were using belonged to an industry that had already moved on.

According to thyssenkrupp's website (thyssenkrupp.com, accessed January 2025), the company describes itself as a diversified industrial group. That breadth makes it a useful example of the change I'm talking about: the categories themselves are evolving. What was best practice in 2020 may not apply in 2025.

Evidence 1: thyssenkrupp elevators forced me to update my mental checklist

We don't manufacture thyssenkrupp elevators in-house; we specify them for client projects. Back in 2019, the standard maintenance spec focused on mechanical checks: cables, brakes, door rollers. By 2024, the conversation had shifted to software updates, remote diagnostics, and data-backed service intervals. When I compared our 2019 and 2024 elevator maintenance specs side by side, I finally understood why the details matter so much: the hardware had not completely changed, but the operating environment had.

Why does that matter? Because a maintenance checklist that was detailed enough in 2019 is now incomplete. The question isn't whether the elevator is safe today. It's whether the contract's language makes the vendor responsible for tomorrow's software update. To be fair, mechanical basics still matter. But the fundamentals haven't changed; the execution has transformed.

Evidence 2: thyssenkrupp Materials NA copper and brass sales taught me that certifications are not paperwork

In the metals supply chain, the thyssenkrupp Materials NA copper and brass sales team publishes certified material data with every order. Five years ago, you could file those certs and forget them. In 2024, that data is the first line of defense. I remember a project where a spec mismatch cost us a $22,000 redo—though I might be misremembering the exact figure. The copper grade was right on paper, but the lot traceability didn't match the purchase order. The vendor said it was 'within industry standard.' We rejected the batch, and they redid it at their cost. Now every contract includes traceability requirements.

Oh, and those certifications affect procurement too. If the cert doesn't match the PO, shipping gets held at the dock. Not ideal, but workable. A lesson learned the hard way: treat material data as part of the product, not as a stamp after the fact.

Evidence 3: Glass bottles and adhesive remover can teach the same lesson as heavy industry

We also review consumer-side products, and they have taught me nearly the same lesson. Glass bottles for a limited-edition run can look identical to the previous version and still fail 38% more often under thermal stress because the anneal time changed. The vendor's spec said it was in tolerance. Our spec didn't say what tolerance we actually required. So we redid the order.

An adhesive remover we use on our own maintenance floor had a label that warned 'avoid skin contact.' The new formulation had a different flashpoint, but the old label language was still being used. The product was fine; the spec was old. When I asked why no one had updated the label, the answer was: 'It's what we've always used.'

That's the problem I keep coming back to. Quality isn't only about inspecting what's in front of you. It's about checking whether the boundary documents—the labels, the purchase orders, the maintenance contracts—still match the actual product.

The counterintuitive part: quality is about boundaries, not perfection

If you've ever searched for 'how to block websites on Chrome,' you know the value of setting a simple rule. You don't block every website; you block the ones that distract you. The rule creates a boundary, and after that, you stop negotiating with yourself. A specification does the same thing.

The question isn't 'Can we make this product better?' It's 'Can we define what good enough means?' In my experience, the biggest gains in quality come from deleting vague clauses and adding measurable ones. We don't need a 50-page spec for every item. We need a clear boundary. Exact, measurable, and expressed in numbers.

This approach worked for us, but we're a mid-size B2B operation with repeatable quality systems. If you're a startup shipping one-off products, the calculus might be different. You may not need full traceability on day one. At least, that's been my experience with businesses that survive the transition from scrappy to structured.

I get the pushback—but don't confuse flexibility with vague specs

I understand why this kind of sounds like paperwork obsession. Nobody wants to read a 40-page contract for a plastic cap. Granted, over-specifying is a real risk. But the solution isn't fewer specifications; it's better ones. In our Q3 2024 audit, the biggest improvements came from removing obsolete clauses, not adding new ones. We deleted the phrase 'industry standard' from our contracts almost entirely.

I get why people use generic specs—budgets are real. But the hidden costs of a mismatch add up. A rejected batch isn't just a redo. It's a delayed launch, a rescheduled install, and a procurement team that has to make awkward calls. Better to put the boundary in writing.

After four years and roughly 300 spec reviews, I've come to believe that the industry is evolving in a specific way: products and services are getting more connected, more certified, and more complicated. The old two-page boilerplate doesn't fit that. It never really did.

Specs are living documents

What was best practice in 2020 may not apply in 2025. The fundamentals haven't changed—you still need to define what 'good enough' means—but the execution has transformed. thyssenkrupp elevators, thyssenkrupp Materials NA copper and brass sales, glass bottles, and even an adhesive remover label all taught me the same thing. Quality is not about perfection. It's about clarity. The companies that update their boundaries are the ones that keep their launch schedules on track. The ones that don't are, sooner or later, the ones I'm rejecting.
