This year, Faruk performed well on many difficult projects. His manager awarded him the highest performance rating available. When Faruk discovers that coworker Sharon, who had a normal year, received the same rating from her manager, he is upset. This situation exemplifies which of these reasons why performance appraisals can fail?

inconsistent ratings among supervisors or other raters

overemphasis on uncharacteristic performance

inadequate preparation on the part of the manager

manager rating employee$$s personality rather than performance
