Here are eight steps to identifying the principal causes you should focus on, using Pareto Analysis: Create a vertical bar chart with causes on the x-axis and count (number of occurrences) on the y-axis. The Pareto Chart shows the relative frequency of defects in rank-order, and thus provides a prioritization tool so that process improvement activities can be organized to "get the most bang for the buck", or "pick the low-hanging fruit". The numbers can be 25-75 or 15-85.
