The cost of performing a control is a consideration for which measure?

In evaluating the performance of a control, the cost associated with implementing and maintaining that control is a critical factor when measuring efficiency. Efficiency in this context refers to achieving desired outcomes with the optimal use of resources, including time and costs. When assessing controls, it is essential to consider whether the benefits gained from those controls justify the costs incurred. High costs with minimal benefits indicate a lack of efficiency.

For instance, if a control designed to mitigate risks is too expensive to implement relative to the risk it is meant to mitigate, it may not be considered an efficient control. Therefore, understanding and analyzing the cost of performing a control directly relates to its efficiency, making this measure crucial in the overall effectiveness of the internal audit process.
