Gold plating is the idea that your developers are spending more time than is necessary to make their code “perfect.”
Generally, we think this is a bad idea.
First off, if your people care about making their work good, don’t punish them for the instinct. It’s good that they care.
But, if you really think it’s happening, and I don’t think it does that much, here’s another way to deal with it. Develop a culture of continuous improvement.
If you have a culture where you go and fix things that aren’t right, then your people won’t feel the pressure that comes from having only one shot at things.
Develop that culture anyway for lots of other benefits too.
