I use Booleans to change the status of a particular record. For instance, an application that helps HR hire an individual may have a table for keeping track of which hoops the applicant has jumped through. After all of the hoops have been jumped through, the user or the app could change the status of a Boolean named AppComplete. Code could automate things and update the field automatically or code could check to make sure the status is available to be changed by the user. In turn, a hire date would not be available until after the status of AppComplete is equal to True.
