I Work for Otis Elevator Co. Here's What a Fence, Some Cabinets, and a Mattress Taught Me About Quality

Last Saturday, I stood in a muddy yard in Otis, Maine, watching a guy install a fence. I wasn't on the clock. But the inspector in my head was definitely on duty. 'If that post isn't plumb, it's gonna show up in the pictures.'

He set a post, eyeballed it, and moved on. I pulled out a tape measure and checked it against the string line. It was off by two inches.

The installer looked at me like I had three heads. The homeowner—my friend Rob—said, 'It's fine. You're doing that quality thing again.'

Yeah. I was.

For context, I'm a quality and compliance manager at Otis Elevator Co. I review field reports and safety audits before they go to customers—roughly 200 a month. In 2024, I rejected 18% of first submissions. Not because I enjoy being the bad guy. Because a missing measurement on an elevator can mean a dangerous ride. A missing measurement on a fence means a crooked yard. Same logic, different stakes.

That's what I assumed, anyway. I thought quality rules were something I left at the office. Then one month, my home projects became a QA audit: a search for fence installation Otis, white kitchen cabinets, a 2 door Bronco, and a late-night text asking 'are memory foam mattresses good?'

The Fence Installation Otis, Maine, and the 'Industry Standard' Trap

When Rob asked me to help him vet contractors, I did what anyone would do: I searched for fence installation Otis. I found a bunch of companies with good reviews. I also found zero information about post spacing, concrete mix, or frost depth.

The guy Rob picked had done a hundred fences. 'Trust me,' he said. Trust is great. Trust is not a specification.

The first sign of trouble was the spacing. Some posts were 7 feet 10 inches apart. Others were 9 feet 1 inch. When I asked what the contract said, the answer was 'standard eight feet.' Fine. But the posts weren't eight feet. They were 'within tolerance,' according to the installer.

Here's the thing: 'within tolerance' without a number is meaningless. In elevator work, we define everything. For a hydraulic elevator, leveling tolerance is usually plus or minus a quarter inch. Door clearance has a spec. Even the lube on guide rails has a spec. If a supplier can't tell you the exact number, they haven't decided what good looks like.

We made the installer redo the spacing at his cost. Rob now has a level fence. He also has a new rule: no contract, no work. That's not over-engineering. That's just writing down what good looks like before you start.

White Kitchen Cabinets Are Never Just White

The same week, our kitchen renovation hit a snag. We'd ordered white kitchen cabinets—which sounds simple, until you realize white is a family of colors, not a color.

The cabinet boxes were one white. The drawer fronts were another. In normal light—or rather, under the LED fixture in my kitchen—you could see it if you were looking. In certain light, it was obvious. The painter said 'close enough.' I said 'What's the tolerance?' He didn't have an answer.

This is where my quality background became useful. Color difference is measured with a metric called Delta E, and the industry standard for brand-critical colors is usually a Delta E of 2 or less. According to Pantone's color matching guidelines, a Delta E of 2 to 4 is noticeable to trained observers. Above 4, it's visible to most people. Our cabinets were sitting around 4.6. That's a fail in my book.

I still kick myself for not specifying the color tolerance in the purchase order. If I'd written 'Delta E under 2' before the contract, the vendor would have had to match it or redo it. Instead, I spent a week arguing with a kitchen company about visible versus claimable.

The fix: the manufacturer remade the drawer fronts. The best part? When they came back, they matched. The satisfaction wasn't about being right. It was about having a standard that prevented the argument in the first place.

My 2 Door Bronco and the 'Good For What' Question

Meanwhile, my neighbor kept asking why I bought a 2 door Bronco. It's not practical. The back seat is cramped, the cargo area is tiny, and my dog has to jump. But I didn't buy it for cargo. I bought it for the trails I actually drive. The question isn't 'is it good?' The question is 'good for what?'

That's a question I wish more people asked about elevators. A high-rise office tower needs a different elevator than a two-story museum. A hospital needs different duty cycles than a condominium. At Otis Elevator Co., we don't ask 'is this elevator good?' We ask 'is this the right elevator for this building's traffic pattern?'

The 2 door Bronco taught me that quality isn't universal. It's contextual. The same spec that makes a vehicle great off-road makes it annoying in a parking garage. Same with elevator speed: a 500 feet-per-minute car might be perfect for a mid-rise and overkill for a residential building. You don't call that a defect. You call that a requirement.

'Are Memory Foam Mattresses Good?' Is the Wrong Question

A few days later, my cousin texted me at 10:42 PM with exactly that: 'are memory foam mattresses good?' I get why people ask. There are a million reviews, and they contradict each other.

My inspector brain kicked in. Good for who? She's a side sleeper with low back tightness. She runs hot. Her partner tosses and turns. Memory foam can be excellent for pressure relief, but it also retains heat. Some people love the body-hugging feel. Others feel stuck. There's no universal answer.

So I gave her a checklist instead of a verdict. Check the foam density—higher density usually means more support, but also more weight and heat. Look for certifications like CertiPUR-US, which means the foam has been tested for certain emissions and chemicals. Check the return policy. And ask what happens after five years, because foam changes.

She ended up with a hybrid. Not because memory foam is bad. Because it wasn't right for her.

The same logic applies to elevator maintenance. A homeowner might ask 'are maintenance contracts worth it?' The honest answer: it depends on the unit, the usage, and the risk you're willing to accept. For a residential elevator, maybe a basic inspection plan is enough. For a hospital, you'd want a full service agreement with response-time guarantees. No shame in asking the question. Just ask the next one: 'for who?'

The Lesson I Keep Relearning

I used to think quality was about rejecting things. It's not. It's about defining acceptance criteria before the work starts. That's true for an elevator safety audit, a fence installation Otis project, white kitchen cabinets, a 2 door Bronco, or a mattress.

Good is not a feeling. Good is a number.

In 2022, I implemented a verification protocol for our field reports: every inspection had to include a date stamp, a photo, and a measured value. Took me a year to get everyone on board. But the number of callbacks dropped significantly. The process wasn't about distrust. It was about making 'good enough' impossible to hide.

The fundamentals haven't changed: define the requirement, verify the result, hold someone accountable. But the tools have. In 2020, I wouldn't have known how to use a colorimeter. In 2025, I carried one into a kitchen showroom. What was best practice in 2020 may not apply in 2025. The discipline, though, is timeless.

I work for Otis Elevator Co., and part of why I'm proud of that is the history: Elisha Otis demonstrated the safety elevator in 1853. Safety has been the point from day one. But you don't need a 170-plus-year legacy to think like an inspector. You just need to decide what good looks like—and then verify it.

Here's my advice, from one recovering perfectionist to another: before you approve anything—a contract, a purchase, a final walkthrough—write down your acceptance criteria. Show it to the other person. Let them argue with it before the work, not after. It will save you money, time, and a lot of late-night arguments with your spouse.

Or as the installer in Otis learned: measure twice, sign once.
