The Matrix is a 4-square grid. The top 2 boxes are respectively labeled Urgent and Not Urgent at the top. The top row is labeled Important to the left, and the bottom row is labeled Not Important.
The Eisenhower matrix expedites time management. You list all the tasks for your day in one or another of the boxes. As you list them in the box, do so by priority. When finished, address the Urgent/Important Tasks immediately and dismiss the Not Urgent/Not Important tasks.
If possible, delegate the items in the Urgent/Not Important box or leave them for the future, when there are no more important tasks. The Non Urgent/Important tasks should be assigned a completion date, but they should never take priority over Urgent/Important tasks.
