What Is Consistency in Performance Measurement?

Aconsistentperformance measure is one that is calculated and reported in the same way over several periods. Consistency allows for meaningful comparisons and trend analysis, making it easier to evaluate performance over time.

Why Consistency Is the Correct Answer:

Performance metrics must remain consistent in methodology, definitions, and scope to ensure the results are comparable across time periods. Without consistency, the reliability and usefulness of the data are diminished.

Why Other Options Are Incorrect:

Timely:Timeliness refers to how quickly the information is reported, not whether it is measured consistently.

Relevant:Relevance ensures the measure is meaningful to the decision-making process, but it does not address consistency.

Reliable:Reliability refers to the accuracy and trustworthiness of the data, not its consistency over time.
