It's not done until it ships

Whenever you are trying to build or create something there will be people who expect you to compromise. They will leverage whatever power they have to push you towards objectives that may not be in the best interest of the product. One of the common pieces of leverage is time. There will be expectations that things are completed by certain dates and times. They will expect you to be done because time says so. And while you can be sure that nothing is final, you will be the one to say it’s done... when it ships.
