#Pareto s Principle - The 80-20 Rule

What It Means

Project Managers know that 20 percent of the work (the first 10 percent and the last 10 percent) consume 80 percent of your time and resources. You can apply the 80/20 Rule to almost anything, from the science of management to the physical world.

You know 20 percent of your stock takes up 80 percent of your warehouse space and that 80 percent of your stock comes from 20 percent of your suppliers. Also 80 percent of your sales will come from 20 percent of your sales staff. 20 percent of your staff will cause 80 percent of your problems, but another 20 percent of your staff will provide 80 percent of your production. It works both ways.

How It Can Help You

The value of the Pareto Principle for a manager is that it reminds you to focus on the 20 percent that matters. Of the things you do during your day, only 20 percent really matter. Those 20 percent produce 80 percent of your results. Identify and focus on those things. When the fire drills of the day begin to sap your time, remind yourself of the 20 percent you need to focus on. If something in the schedule has to slip, if something isn t going to get done, make sure it s not part of that 20 percent.

There is a management theory floating around at the moment that proposes to interpret Pareto s Principle in such a way as to produce what is called Superstar Management. The theory s supporters claim that since 20 percent of your people produce 80 percent of your results you should focus your limited time on managing only that 20 percent, the superstars. The theory is flawed, as we are discussing here because it overlooks the fact that 80 percent of your time should be spent doing what is really important. Helping the good become better is a better use of your time than helping the great become terrific. Apply the Pareto Principle to all you do, but use it wisely.
