Which of the following is NOT used to evaluate process performance?

In the context of evaluating process performance, process compliance is not considered a measure of performance effectiveness. Instead, it focuses on whether processes are being followed as defined, according to established standards and procedures. While adherence to processes is important for ensuring that processes are executed correctly, it does not directly assess how well the processes are achieving their intended outcomes.

On the other hand, schedule predictability, resource cost, and delivered functionality are all critical indicators of process performance. Schedule predictability assesses how accurately the project timeline estimates match actual performance, resource cost evaluates the financial efficiency in resource utilization, and delivered functionality measures the outcomes in relation to what has been promised or required. These metrics collectively provide a more holistic view of how effectively a process is performing in delivering value and meeting organizational goals.
