Techniques of Performance Appraisal Quiz

PDF page 263: Although countless variations on these themes can be found, the basic methods presented provide a good summary of the commonly available techniques. Following this review, we will consider the various strengths and weaknesses of each technique. Six techniques are reviewed here: (1) graphic rating scales, (2) critical incident technique, (3) behaviorally anchored rating scales, (4) behavioral observation scales, (5) management by objectives, and (6) assessment centers.

The rater is then asked to rate the employee by assigning a number or rating on each of the dimensions. An example of a graphic rating scale is shown in Table 8.1.

PDF page 264: By using this method, if we assume that evaluator biases can be minimized, it is possible to compare employees objectively. It is also possible to examine the relative strengths and weaknesses of a single employee by comparing scores on the various dimensions. However, one of the most serious drawbacks of this technique is its openness to central tendency, strictness, and leniency errors. It is possible to rate almost everyone in the middle of the scale or, conversely, at one end of the scale. In order to control for this, some companies have assigned required percentage distributions to the various scale points. Supervisors may be allowed to rate only 10 percent of their people outstanding and are required to rate 10 percent unsatisfactory, perhaps assigning 20 percent, 40 percent, and 20 percent to the remaining middle categories. By doing this, a distribution is forced within each department. However, this procedure may penalize a group of truly outstanding performers or reward a group of poor ones.

PDF page 264: With the critical incident technique of performance appraisal, supervisors record incidents, or examples, of each subordinate’s behavior that led to either unusual success or unusual failure on some aspect of the job. These incidents are recorded in a daily or weekly log under predesignated categories (planning, decisionmaking, interpersonal relations, report writing). The final performance rating consists of a series of descriptive

PDF page 267: The critical incident method provides useful information for appraisal interviews, and managers and subordinates can discuss specific incidents. Good qualitative information is generated. However, because little quantitative data emerge, it is difficult to use this technique for promotion or salary decisions. The qualitative output here has led some companies to combine the critical incident technique with one of the quantitative techniques, such as the rating scale, to provide different kinds of feedback to the employees.

PDF page 268: An appraisal system that has received increasing attention in recent years is the behaviorally anchored rating scale (BARS). This system requires considerable work prior to evaluation but, if the work is carefully done, can lead to highly accurate ratings with high inter-rater reliability. Specifically, the BARS technique begins by selecting a job that can be described in observable behaviors. Managers and personnel specialists then identify these behaviors as they relate to superior or inferior performance. An example of this is shown in Exhibit 8.4, where the BARS technique has been applied to the job of college professor. As shown, as one moves from extremely poor performance to extremely good performance, the performance descriptions, or behavioral anchors, increase. Oftentimes, six to ten scales are used to describe performance on the job. Exhibit 8.4 evaluates the professor’s organizational skills. Other scales could relate to the professor’s teaching effectiveness, knowledge of the material, availability to students, and fairness in grading. Once these scales are determined, the evaluator has only to check the category that describes what she observes on the job, and the employee’s rating is simultaneously determined. The BARS technique has several purported advantages. In particular, many of the sources of error discussed earlier (central tendency, leniency, halo) should be significantly reduced because raters are considering verbal descriptions of specific behaviors instead of general categories of behaviors, such as those used in graphic rating scales. In addition, the technique focuses on job-related behaviors and ignores less relevant issues such as the subordinate’s personality, race, or gender. This technique should also lead to employees being less defensive during performance appraisals, because the focus of the discussion would be actual measured behaviors, not the person. Finally, BARS can aid in employee training and development by identifying those domains needing most attention.

PDF page 269: On the negative side, as noted above, considerable time and effort in designing the forms are required before the actual rating. Because a separate BARS is required for each distinct job, it is only cost-efficient for common jobs. Finally, because the technique relies on observable behaviors, it may have little applicability for such jobs in such areas as research science (and sometimes management), where much of the work is mental and relevant observable behaviors are difficult to obtain.

PDF page 269: The behavioral observation scale (BOS) is similar to BARS in that both focus on identifying observable behaviors as they relate to performance. It is, however, less demanding of the evaluator. Typically, the evaluator is asked to rate each behavior on a scale from 1 to 5 to indicate the frequency with which the employee exhibits the behavior. Evaluation of an employee’s performance on a particular dimension is derived by summing the frequency ratings for the behaviors in each dimension. For example, in Table 8.3 we can see an example of a form to evaluate a manager’s ability to overcome resistance to change. The rater simply has to circle the appropriate numbers describing observed behaviors and get a summary rating by adding the results. The BOS technique is easier to construct than the BARS and makes the evaluator’s job somewhat simpler. Even so, this is a relatively new technique that is only now receiving some support in industry.
