Answer:
to rank tasks from most to least important
Explanation:
Prioritize means to choose priority, obviously and priority is the thing is the thing which, among other things, have the biggest importance.
Every day, especially in business, one finds himself swimming in tasks up to his neck. Obviously, not all of them can be successfully finished, or at least not without sacrificing one's personal life or sleep.
Prioritizing, therefore, serves as a helpful organising tool. After writing down all tasks that need to be done, a person should rank them by priority, which means that only urgent and important tasks will be dealt with immediately. Tasks of lower priority will be postponed, delegated or simply deleted.
