In relation to performance management and performance measures, reliability refers to A. whether an employee can be counted on to perform at a high level. B. the consistency with which two or more managers rate performance when presented with comparable information. C. whether a performance measure measures what it is intended to measure. D. the extent to which factors out of the employee's control affect performance.

In the world of performance management, reliability is all about consistency. Imagine two managers evaluating the same employee based on identical criteria—if they come to similar conclusions, that’s a good sign of reliability! This ensures that evaluations aren't just a matter of personal bias or random guessing. When it comes to performance measures, validity is your best friend! It's crucial to have measures that accurately reflect what they’re supposed to evaluate. For instance, if you’re measuring productivity, your metrics should directly relate to the employee's actual output, rather than unrelated factors like office distractions. Valid measures help drive genuine improvements!
