Performance Appraisal Techniques or Methods

Performance Appraisal Techniques or Methods

There are many types of performance appraisal methods. Those are divided in two parts

  • Traditional Methods
  • Modern Methods

 

Traditional Methods

Rating Scales

The rating scale method offers a high degree of structure for appraisals. Each employee trait or characteristic is rated on a bipolar scale that usually has several points ranging from “poor” to “excellent” (or some similar arrangement). The traits assessed on these scales include employee attributes such as cooperation, communications ability, initiative, punctuality and technical (work skills) competence. The nature and scope of the traits selected for inclusion is limited only by the imagination of the scale’s designer, or by the organization’s need to know. The one major provision in selecting traits that they should be in some way relevant to the appraisee’s job. The traits selected by some organizations have been unwise and have resulted in legal action on the ground of discrimination (Torre, 1996)

Advantages

The greatest advantage of rating scales is that they are structured and standardized. This allows ratings to be easily compared and contrasted – even for entire workforces.

Each employee is subjected to the same basic appraisal process and rating criteria, with the same range of responses. This encourages equality in treatment for all appraise and imposes standard measures of performance across all parts of the organization (David, 1993). Rating scale methods are easy to use and understand. The concept of the rating scale makes obvious sense; both appraiser and appraise have an intuitive appreciation for the simple and efficient logic of the bipolar scale.

This result is widespread acceptance and popularity for this approach.

Disadvantages

  • Trait Relevance: Are the selected rating-scale trait clearly relevant to the jobs of all appraises? It is inevitable that with a standardized and fixed system of appraisal that certain traits will have a greater relevance in some jobs than in others. For example, the trait “initiative” might not be very important in a job that is tightly defined and rigidly structured. In such cases, a low appraisal rating for initiative may not mean that an employee lacks initiative.
  • Systemic Disadvantage: Rating scales, and the traits they purport to measure, generally attempt to encapsulate all the relevant indicators of employee performance. There is an assumption that all the true and best indicators of performance are included, and all false and irrelevant indicators are excluded (Torre, 1996).
  • Perceptual Errors: This includes various well-known problems of selective perception (such as the horns and halos effect) as well as problems of perceived meaning. Selective perception is the human tendency to make private and highly subjective assessments of what a person is “really like “ and then seek evidence to support that view (while ignoring or downplaying evidence that might contradict it).
  • Perceived Meaning: Problesms of perceived meaning occur when appraisers do not share the same opinion about the meaning of the selected traits and the language used on the rating scales. For example, to one appraiser, an employee may demonstrate the trait of initiative by reporting work problems to a supervisor.
  • Rating Errors: The problem here is not so much errors in perception as errors in appraiser judgment and motive. Unlike perceptual errors, these errors may be (at times deliberate. The most common rating error is central tendency.

 

 

Essay Method

In the essay method approach, the appraiser prepares a written statement about the employee being appraised. The statement usually concentrates on describing specific strengths and weakness in job performance. It also suggests courses of action to remedy the identified problem areas (Harry, 2007).

The statement may be written and edited by the appraiser alone or it can be composed in collaboration with the appraisee.

Advantages

The essay method is far less structured and confining than the rating scale method. It permits the appraiser to examine almost any relevant issue or attribute of performance. This contrasts sharply with methods where the appraisal criteria are rigidly defined (Harry, 2007).

Appraisers may place whatever degree of emphasis on issues or attributes that they feel appropriate. Thus the process is open-ended and very flexible.

The appraiser is not locked into an appraisal system the limits expression or assumes that employee traits can be nearly dissected and scaled.

Disadvantages

Essay methods are time –consuming and difficult to administer. Appraisers often find the essay technique more demanding then methods such as rating scales.

The techniques greatest advantage – freedom of expression – is also its greatest handicap. The varying writing skills of appraisers can upset and distort the whole process .The pricess is subjective and in consequence, it is difficult to compare and contrast the result of individuals or to draw any broad conclusion about organizational needs (Christopher, 2006).
