Eisenhower Matrix is one of the most popular time management tools. All tasks are evaluated using the criteria critical/not critical and immediate/not immediate and put in according quadrants. Tasks in not critical/not immediate are dropped, tasks in critical/immediate are done immediately and personally, tasks in not critical/immediate are delegated and tasks in critical/not immediate get an end date and are done personally. This method is said to have been used by U.S. President Dwight D. Eisenhower, and is outlined in a quote attributed to him: “What is important is seldom urgent and what is urgent is seldom important”.
