Pareto analysis is a powerful tool in statistical process control (SPC) that helps you identify and prioritize the most significant causes of quality problems. By applying the 80/20 rule, you can focus on the few factors that account for the majority of the variation or defects in your process.

1 Understand the basics

Before you start using Pareto analysis, you need to have a clear understanding of its purpose, principles, and steps. Pareto analysis is based on the Pareto principle, which states that 80% of the effects come from 20% of the causes. In SPC, this means that 80% of the quality problems are caused by 20% of the factors. To perform Pareto analysis, you need to follow these steps: 1) Identify and list the potential causes of quality problems; 2) Collect and measure data on the frequency or severity of each cause; 3) Rank the causes from highest to lowest impact; 4) Plot the causes on a Pareto chart, which is a bar graph that shows the cumulative percentage of the total effect; 5) Analyze the chart and identify the vital few causes that require immediate attention.

This basics is the most important aspect of identifying the 20%. Go to the place of value (Gemba). Work with the people on the floor to get a better understanding of the actions being done that give you the data that you think is the vital few. Get their inputs. Activily involve the experts in the process (People). Employ their feedback.

Interesting SIPOC flow. "Where are the "Worker Bees". Seems the actual value-added-step is not considered. The viewpoint of peers, mentors, managers, customers or stakeholders are all outside the main process. (Outide-looking-in) can hide many of the root causes being investigated or searched for.

6 Review and revise

A fifth way to learn and improve your Pareto analysis skills in SPC is to review and revise your work regularly. Pareto analysis is not a one-time activity, but a continuous process of monitoring and improving your quality performance. You need to review and revise your Pareto analysis whenever there are changes in your process, data, or goals. By reviewing and revising your work, you can learn how to adapt to changing conditions, how to update your charts, and how to measure your progress and results.
