Question

Quizplus · Accepted Answer

The 80/20 principle, also known as the Pareto principle, states that roughly 80% of effects come from 20% of causes. Statistical process control charts are based on the principles of control and variation, and are used to monitor and improve a process over time. While the two concepts may be related in certain contexts, the 80/20 principle is not the basis for statistical process control charts.
