on each job dimension) of one employee with that of others to establish a rank order of performanceProblems:-Provide no information on how the employee performs on different job dimensions-Cannot be used for developmental or training purposesFour relative rating systems:
1.Rank order2.Paired comparisons3.Forced distribution4.Relative percentile methodRank order: rank employees in order of their perceived overall performanceProblems:-May have idea of who the best and worst performers are but often have difficulty assigning ranks to the remaining employees-System is relative so does not tell whether any or all of the workers are performing above or below acceptable levelsPaired comparisons: compare overall performance of each worker with that of every other worker who must be evaluated then rank on the basis of the number of times they were selected as the top-rated performer over all the comparisonsProblem:-Large number of comparisons that have to be made (tedious, rush the procedure)-Does not provide information on absolute performance levels-Best for small samplesForced distribution: sets up a limited number of categories that are tied to performance standards and the rater is forced to place a predetermined number percentage of workers into each of the rating categoriesProblems:-Having a set percentage to place into extreme categories distorts the true state of affairs-Useful with large samples-Assumes employee performance is normally distributed-Negative reactionsRelative Percentile Method (RPM): compare individuals on job performance dimensions that have been derived through job analytic procedures-Requires rater to use a 101-point scale (0 to 100)-Score of 50 represents average performance-For each performance dimension, or for the global comparison, a rater uses the scale to assess each ratee relative to one another-Anchors each rater’s comparison to an absolute standard, and thus allows meaningful comparisons among ratings obtained from different raters-Produces validity estimates and levels of accuracy that surpass those obtained with some absolute rating scales-Best relative rating method
Absolute rating systems: compare the performance of one worker with an absolute standard of performanceDeveloped to provide either an overall assessment of performance or assessments on specific job dimensionsFour methods:1.Graphic rating scales2.Critical incidents3.Behaviorally anchored rating scale4.Behavior observation scalesGraphic rating scales: usually consist of the name of the job component or dimension, abrief definition of the dimension, a scale with equal intervals between the numbers placedon the scale, verbal labels or anchors attached to the numerical scale, and instructions for making a responseJudgment of “how much” of a trait or factor an employee hasCritical incidents: behaviors that result in good or poor job performanceBehaviorally Anchored Rating Scales (BARS): uses job behaviors derived through a
