What do you do to cut development time?

Originally, I was asking if there are ways to cut development time by striking a good balance between prefection and efficiency. For example, I wanted to create assets by scratch, and I want to get it done quick, but I need to take time drawing the art assets to make it look nice, and engineer sounds to make it lively.

Of course, the answer is to delegate the tasks to third-party producers, or increase the budget/extend the planned deadline further.

Now, I want to ask what else do you do to cut down development time, even if it’s not completely related to development? I might get some valuable tips as an hobbyist/indie guy.
