What barrier does the 'No Uniform Standards' limitation present in performance appraisal?

The 'No Uniform Standards' limitation in performance appraisal signifies a lack of consistent criteria or benchmarks for evaluating employee performance. When there are no established standards, performance ratings become unscientific and subjective, as evaluators may rely on personal judgment, biases, and individual interpretations of performance rather than objective criteria. This subjectivity can lead to discrepancies in evaluations, making it challenging to maintain fairness and accuracy across different employees or teams.

Without uniform standards, it becomes difficult to compare performance consistently, which can affect decisions related to promotions, raises, or development opportunities. Uniform standards serve to create a level playing field where evaluations are based on clear, pre-defined criteria, which helps ensure that all employees are measured against the same expectations, ultimately enhancing the credibility of the appraisal process.
