I've been doing this job for a long time now. When I started, you'd often learn about a tricky issue by chatting with the building staff while on site. They'd tell you about little sounds or habits the elevator had that no sensor would pick up. Now, we mostly get work orders from a computer and go straight to the machine. It gets the job done quick, but you lose that personal touch. I think those talks helped us understand the whole system better. It made the work feel more connected to the people using it every day.
In my experience, I used to feel rushed on complex repair jobs and would skip steps. But helping my daughter build a model rocket over the weekend showed me how breaking things into small parts works better. Now I write out each task for a job before I start, and it keeps me from making silly mistakes. Your mileage may vary, but it has made my work days smoother.
