efforttovalue
Effort-to-value, abbreviated as ETV, is a metric used to evaluate the efficiency of a task, decision, or design by comparing the amount of effort required to the value or payoff obtained. It can be expressed as a ratio or through a functional form, with common formulations including ETV = effort / value or its reciprocal value-to-effort. In many applications, a lower ETV signifies greater efficiency, meaning less effort is needed to achieve a unit of value.
Effort and value are context-dependent and can be quantified in various ways. Effort might be measured in
Applications of ETV span fields such as human–computer interaction, product design, workflow optimization, and decision analysis.
Limitations include the subjectivity of value, variability across users and contexts, and sensitivity to how effort
