One view on how to do good performance reviews: The foundation of your performance evaluation system is the job description you wrote for each of your employees. A supervisor need only compare an employee’s performance against standards you identified in a job description to discover whether an employee does a job competently.
Your evaluation process is as simple as that. Or is it? Your job descriptions might be the best ones around. But they don’t guarantee good performance evaluations.
Why? More often than not, it’s the supervisors who gum up the process by inadequately comparing an employee’s performance against well-defined job standards.
