The Pareto principle states that:
A) The majority of nonconformities are caused by a relatively small percentage of the total set of problems. Improvement efforts should be focused on these critical problems.

The Pareto principle, often referred to as the 80/20 rule, suggests that roughly 80% of effects come from 20% of causes. In the context of quality management, this means that a majority of problems (nonconformities) can usually be traced back to a small number of root causes. Focusing improvement efforts on these critical issues is therefore more efficient. The other options misrepresent the principle or its applications.
