Even though it's inevitable that you'll change your mind about something on your project, know this: Every time you change your mind, it'll result in a change order.

Everyone working on the job needs to be informed of the change so no one's working on the old plan. Everyone makes changes, and that's OK — just be aware of the potential to disrupt and delay the job.
