Real Process Improvement Comes from the Shop Floor

One of the most important lessons I learned during my time at Parker was that good process improvement work does not start with assumptions. It starts with conversations.

When engineers look at a process from a distance, it is easy to focus on what seems more efficient in theory. On paper, a new sequence, a different layout, or an added control step can look like a clear improvement. But manufacturing does not happen on paper. It happens in the real world, with real people, real constraints, and real tradeoffs.

That is why I learned how important it is to talk to operators and the people on the shop floor before making changes.

There were many situations where I was involved in improving different steps in the manufacturing process. At first glance, there were often ideas that appeared better from a technical or theoretical perspective. But instead of automatically choosing the option that looked best in theory, I made it a priority to understand what worked best in practice.

The people doing the work every day usually have the most honest and detailed understanding of the process. They know which steps slow things down, which actions are repetitive but necessary, which ones are truly wasteful, and which small details are easy to overlook unless you have actually done the job yourself. They also understand the practical realities that may not show up in a process map, standard work document, or improvement proposal.

By talking to operators, I was able to ask better questions. What part of the process feels unnecessary? Where do delays happen most often? Which motions add no value? What causes frustration? What would make the job easier, smoother, or more consistent? Those conversations gave me insights that I could not have gotten by only studying the process from an engineering standpoint.

What I found was simple but important. The best improvements were usually not the ones that looked the most impressive. They were the ones that made the work more practical, more realistic, and easier to execute consistently. In many cases, the right answer was not the most theoretical answer. It was the one that made sense in the actual working environment.

That experience changed the way I think about improvement work. It reminded me that engineering is not just about optimizing systems. It is about designing solutions that people can actually use. A process is only better if it works better in real life.

Talking to operators also builds trust. When people on the floor see that their experience is being taken seriously, they are more likely to support the change and help make it successful. That matters because process improvement is not only about finding a better method. It is also about creating changes that people understand, accept, and can sustain over time.

Looking back, one of the biggest mistakes an engineer can make is believing that the best answer comes only from analysis, calculations, or documentation. Those things matter, but they are not enough on their own. Some of the most valuable knowledge in any manufacturing environment comes from the people closest to the work.

That is why I believe strong process improvement requires both technical thinking and practical humility. You have to be willing to step away from the desk, go to the floor, ask questions, and listen carefully. The best solutions are often not invented in isolation. They are uncovered through observation, discussion, and respect for the people who know the process best.

In manufacturing, what looks good on paper does not always work in reality. The most effective improvements come from understanding both.
