Performance Appraisal Rating - Methods of Performance Appraisal (7 Marks)

Definition

Performance Appraisal (PA) is a systematic and periodic evaluation of an employee's job performance and potential for development against pre-set standards. Rating refers to the scale/judgement used to quantify performance.

Objectives of PA

Administrative (promotion, increments, transfer), Developmental (training needs, feedback), Organizational (HR planning, validating selection criteria)

Methods / Techniques of Performance Appraisal Rating

A. Traditional / Past-Oriented Methods

1. Graphic Rating Scale (Most Popular):
Lists traits (quality, quantity, dependability, initiative) with continuum scale (e.g., 1-5 Poor to Excellent). Simple, low cost, but prone to halo error and subjectivity.

2. Forced Choice Method:
Rater must choose between two equally favourable/unfavourable statements (e.g., "hardworking" vs "regular"). Reduces leniency bias but frustrating for raters.

3. Forced Distribution Method:
Rater distributes employees into predetermined categories approximating normal distribution (e.g., 10% Excellent, 20% Above Average, 40% Average, 20% Below Average, 10% Poor). Eliminates central tendency but creates artificial differentiation. Used by GE (20-70-10 vitality curve).

4. Ranking Methods:

• Straight Ranking: Rank from best to worst.
• Paired Comparison: Compare each employee with every other (N(N-1)/2 comparisons). Suitable for small groups.
• Alternation Ranking: Choose best, then worst, alternatively.

5. Critical Incident Method:
Supervisor records critical incidents of exceptionally good/bad behaviour throughout period and rates based on those. Provides specific behavioural examples, but time-consuming and no quantitative score.

6. Essay / Free Form Method:
Rater writes essay describing strengths, weaknesses, potential. Subjective and variable.

7. Checklist Method:
List of statements; rater checks "Yes/No" if applies. Weighted checklist assigns different weights to each item.

8. Confidential Report (ACR):
Used in government; superior writes descriptive report on performance, conduct, character; kept confidential.

B. Modern / Future-Oriented Methods

9. Management by Objectives (MBO) - Peter Drucker:
Joint goal setting by superior-subordinate, periodic review against measurable objectives. Focuses on results, not traits. Steps: Set organizational goals -> Set individual goals -> Monitor -> Evaluate. Limitation: Too results-oriented, time-consuming.

10. Behaviourally Anchored Rating Scales (BARS):
Combines critical incident + rating scale. Performance dimensions are anchored with specific behavioural examples of good/average/poor. E.g., for "Customer Service": 7=Handles complaint with empathy and solution (Excellent), 4=Politely forwards complaint, 1=Argues with customer. Most reliable and valid, reduces rating errors, but expensive to develop.

11. Assessment Centres:
Employees undergo simulations, in-basket exercises, role plays, psychometric tests evaluated by multiple assessors. Used for potential appraisal and promotion. High validity.

12. 360-Degree Feedback (Multi-Rater):
Feedback from superior, peers, subordinates, customers and self. Provides holistic view, reduces bias, useful for development. Requires anonymity and trust; can be stressful.

13. Cost Accounting / Human Resource Accounting Method:
Evaluates employee in monetary terms - cost incurred vs contribution (revenue generated).

14. Psychological Appraisals:
Uses psychologists with tests, interviews to assess potential rather than past performance.

Rating Errors to Avoid (Important for 7M)

Halo effect, Horn effect, Leniency/Strictness, Central Tendency, Recency, Contrast, Stereotyping, Spillover, Similar-to-me bias. Training of raters (Rater Training) is essential.

Essentials of Good Appraisal System

Clear standards, job-related, trained appraisers, open communication and feedback (Appraisal Interview), post-appraisal counselling, linkage to rewards, documentation.

Conclusion

No single method is perfect. Modern organizations prefer combination - e.g., MBO + BARS + 360-degree for both administrative and developmental purposes. Choice depends on purpose, size, cost and culture. For exam, recommend BARS and 360-degree as most effective contemporary rating methods.
