Q129 - Rating Errors in Performance Appraisal & Competency Management (7 Marks)

A. Rating Errors in Performance Appraisal

Performance appraisal should be objective, but rater's subjective bias introduces rating errors that reduce validity and reliability.

1. Concept

Rating error is systematic distortion in evaluation due to psychological, social or methodological factors on part of rater, ratee or system.

2. Major Rating Errors

Error	Meaning	Example
Halo Effect	One outstanding trait colours entire evaluation positively	Good communicator rated high on technical skills too
Horn Effect	One negative trait colours entire evaluation negatively	Late once → rated low on all dimensions
Leniency Bias	Tendency to give generous ratings to all	Avoids conflict, rates everyone 4/5
Strictness Bias	Tendency to give harsh ratings	Very demanding rater, no one exceeds 2/5
Central Tendency	Clustering ratings around midpoint, avoiding extremes	All rated 3/5 to be “safe”
Recency Effect	Recent behaviour dominates over whole period	Poor performance 11 months, good last month → high rating
Primacy Effect	First impression dominates	Opposite of recency
Contrast Error	Rating influenced by previous employee rated	Average employee after poor one appears excellent
Similar-to-me / Liking Bias	Favouring those similar to rater	Rater favours employees from same college/region
Stereotyping	Judging based on group stereotype	“Women not suitable for field jobs”
Spillover Effect	Past appraisal carries forward	Past poor rating influences current despite improvement

3. Ways to Minimise Errors

• Use BARS, MBO, 360-degree feedback, forced distribution, ranking
• Rater training (Frame-of-Reference training)
• Multiple raters, calibration meetings, anchoring with critical incidents
• Maintain diary/ continuous documentation, not memory-based
• Clear job-related criteria, Behaviourally Anchored statements

Exam tip (7M): Define error → list 6-7 types with 1-line example → conclude with 2-3 remedies.

B. Competency Management

1. Definition

Competency is a cluster of knowledge, skills, attitudes (KSAs) and motives that differentiates superior from average performance in a job. Competency Management is systematic process of identifying, mapping, developing and aligning competencies with organisational strategy (McClelland, Boyatzis).

Competency vs Competence: Competence = ability to do job; Competency = behaviour leading to competence.

2. Types of Competencies

• Core competencies: Organisation-wide (e.g., Tata – customer centricity)
• Functional/Technical: Job-specific (e.g., coding for IT, audit for finance)
• Behavioural/Generic: Leadership, communication, teamwork
• Threshold vs Differentiating: Minimum needed vs what distinguishes top performers

3. Competency Management Process

1. Competency Mapping: Job analysis → identify competencies via interviews, BEI (Behavioural Event Interview)
2. Competency Framework / Dictionary: Define 8-12 competencies with proficiency levels (1-5)
3. Assessment: 360°, assessment centre, psychometric tests
4. Gap Analysis: Current vs required level
5. Development: Training, coaching, job rotation, mentoring
6. Integration with HRM: Recruitment (competency-based interviewing), Performance appraisal, Succession planning, Compensation, Career planning

4. Example – Competency Model for Manager

• Leadership – Level 3: Inspires team, coaches juniors
• Result Orientation – Level 4: Consistently exceeds targets
• Communication – Level 3: Presents effectively to stakeholders

5. Importance / Benefits

• Aligns HR with strategy, improves selection accuracy
• Objective appraisal, reduces rating errors
• Identifies training needs, builds talent pipeline
• Enhances productivity, retention and competitive advantage

Conclusion: While rating errors make traditional appraisal subjective, competency management makes it behaviour-based, future-oriented and strategic, shifting focus from past performance rating to future capability building.
