When do you consider a job to be finished?

This question is not only asking about your work habits but also about how conscientious you are on the job. Think about all of the things you do in order to make sure a job is complete. For example, you might consider a job to be finished if you've followed all policies and procedures, checked in with a supervisor, had another team member check your work, were certain all safety precautions have been taken, or you wrote down in a journal that the job was complete and what was done.
