Why is the Pareto chart commonly associated with the 80/20 rule?

The Pareto chart is a graphical representation that helps identify the most significant factors in a dataset, illustrating the principle known as the 80/20 rule. This rule suggests that 80% of consequences come from 20% of the causes. In the context of sales and products, this means that a relatively small number of products—specifically, 20%—are responsible for the majority of sales volume, which amounts to roughly 80%.

This insight allows businesses to focus their efforts on the most impactful products to maximize sales and improve overall performance. By recognizing that a small selection of products generates most of the revenue, companies can prioritize inventory management, marketing strategies, and customer support for those key items to drive better business outcomes.

The other options do not accurately reflect the principles of the Pareto chart or the 80/20 rule in this context. For instance, the claim about 80% of products contributing minimally to sales doesn't capture the essence of prioritizing key products, while assertions about new products or promotional items divert from the core idea of establishing which existing products are the most critical for revenue generation.
