Completing a performance appraisal is one of the most difficult tasks assigned to managers. The following points summarize a few of the common errors made by managers as they conduct evaluations.  

1. The Halo Effect

Allowing one highly favourable (or unfavourable) employee behaviour or characteristic to affect judgement about the entire appraisal ignores other employee strengths and weaknesses.  

2. Bias or Prejudice

We all have our biases. However, allowing personal biases or prejudices to influence the appraisal process can make evaluations unfair and inconsistent. Know your biases.  

3. Not Knowing Employees

Allowing one highly favourable (or unfavourable) employee behaviour or characteristic to affect judgement about the entire appraisal ignores other employee strengths and weaknesses.  

2. Overemphasis

We all have our biases. However, allowing personal biases or prejudices to influence the appraisal process can make evaluations unfair and inconsistent. Know your biases.
