What methods can I use to establish priorities, multi-task, meet deadlines, and ensure accuracy of my work? What methods or systems can I use to ensure that all information is gathered and accounted for and that no detail is overlooked?

Is this a schoolwork/homework question? I'm guessing your textbook or a few books listed on the syllabus will contain this information. (Mine did.)
