The correct answers are A, C, D, and E . Pareto’s law of distribution, often expressed as the 80/20 principle , is used in Value Methodology to focus team attention on the “vital few” items that create the greatest effect. In a VM study, this principle helps the team avoid spreading effort equally across all issues and instead concentrate on the limited number of elements that drive most of the project impact.

It can be applied to time , because a small number of activities often consume most of the schedule or create major delay exposure. It can be applied to quality , because a limited group of defects, failures, or performance gaps may account for most quality problems. It can be applied to risk , because a small number of risk events often carry the largest probability-impact burden. It is also highly applicable to costs , because VM studies commonly use cost models and cost distribution to identify high-cost elements for function analysis and value improvement.

Standards are not normally treated as Pareto-distributed variables; they are requirements or constraints. Performance is important in VM, but Pareto application is more directly tied to measurable distributions such as cost, time, quality problems, and risk exposure.
