Which statement best describes the Formula element?

Which statement best describes the Formula element?

• A. A clear description of the feature being evaluated
• B. A numeric measurement
• C. A Recommended Action
• D. How changes in the criterion value affect desirability

Answer: (D)

The Formula element defines how a criterion’s value is turned into a desirability score. It specifies the mathematical relationship that shows what happens to desirability as the criterion value increases or decreases, which can be linear, curved, or have thresholds. This is what lets you compare different options on a common scale, because it captures whether small improvements are valued more or less as you move along the criterion, and where gains level off or accelerate. The other options describe what is being measured, the raw measurement itself, or a recommended action, none of which explain how changes in the criterion value influence desirability through a formula.
