Just think about it.
80% of the world’s income is controlled by 20% of the world’s population.
80% of the work done in any company is only from 20% of the staff.
80% of the sales in any business are only from 20% of the clients.
80% of all computer crashes are caused by 20% of the most reported bugs.
80% of the time, we wear are 20% of our favourite clothes.
In all events, roughly 80% of its effects come from 20% of its causes.
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.
