Let's make sure there are no loose ends.
Sometimes a 2nd trip or a special item is needed. We have a special process for keeping track of things. We log follow up requirements, parts, additional work, etc. with a due date so we know what is needed and when it needs to be done. Special material have their own tracking arrangement so we know what needs to be ordered and when it is due in. We can schedule the next trip based on the expected availability
