Pareto Chart

The Pareto Principle is that 80% of a problem is usually caused by 20% of the underlying cases. A Pareto chart can help a team quickly identify which  causes have the most impact on the problem.  This tool  allows  teams to then focus on those causes that will have the greatest impact if solved or improved.

How would I use this tool differently at different stages of the Improvement Journey?

Pareto Charts are often used to:

  • Display numeric data on several potential causes
  • Identify the causes that are most frequently leading to the problem
  • Bring focus to a small number of potential causes
  • Guide the process of selecting changes to test
