Pareto's Law in the context of cost control states which of the following?

Pareto's Law in the context of cost control states which of the following?

• A. 80% of a project's outcome is determined by 50% of its elements.
• B. 80% of a project's outcome is determined by 20% of its elements.
• C. 20% of the project outcome is determined by 80% of its elements.
• D. Pareto's Law relates to time management.

Answer: (B)

Pareto's principle, often called the 80/20 rule, says a small set of causes drives the majority of effects. In cost control, this means a minority of cost drivers create most of the project costs, so focusing effort on those drivers yields the biggest impact. The statement that 80% of the project's outcome is determined by 20% of its elements perfectly captures that idea, highlighting the uneven distribution of influence. The other formulations either flip the ratio, imply a more even spread, or misapply the concept to time management, which isn’t the core point. In practice, identify the few elements that contribute most to cost or value and manage them closely, since improvements there yield the largest returns.
