The biggest mistake I see elevator company owners make when they try to grow

They hire more people before fixing the process. The logic sounds right: more jobs coming in, need more hands. But if the process is broken, more hands just means more people doing the broken process faster.

Then those new people need to be managed, coordinated, chased, which comes back to the owner. The pattern across hundreds of companies in this industry: the owners who scale well fix the process first, then grow the headcount.

The ones who struggle do it the other way around. Same lesson applies to pretty much every service business. You don't scale by adding people. You scale by making the process clear enough that the right number of people can execute it without you.
