The Action Priority Matrix is a simple diagramming technique that helps you choose which activities to prioritize (and which ones you should drop) if you want to make the most of your time and opportunities during any day. Most shop owners have many more activities on their "wish lists" — whether these are bright ideas to pursue, exciting opportunities or interesting possibilities — than they have time available. The matrix helps one choose activities intelligently to make the most of the time and opportunities available by focusing on the activities that optimize effort and impact.
