The person who will maintain the result belongs in the conversation before it is finished.

Design and upkeep are usually done by different people, and only one of them is in the room. Decisions get made for the launch, the opening, the handover, while everything that follows lands on whoever has to live with it: the person cleaning it, running it, answering for it at eight in the morning. They can often see in five minutes what will fail in a year.

Before your next decision is final, find whoever will maintain the result and ask what they would change. Do it while changing things is still cheap. Their objections are a forecast rather than resistance.
