Exam 5: Performance Management

Correct Answer:

Answered by Examlex AI Copilot

Behaviorally Anchored Rating Scales (BARS) and Behavioral Observation Scales (BOS) are both methods used in performance management to evaluate an employee's performance. While they share some similarities, they also have distinct differences. Here's a comparison of the two systems:

**Behaviorally Anchored Rating Scales (BARS):**

1. **Definition**: BARS is a performance appraisal method that combines elements of the traditional rating scales and critical incidents methods. It uses specific behavioral examples (critical incidents) that are anchored to numerical ratings.

2. **Development**: To create a BARS, job behaviors are identified, and then critical incidents demonstrating those behaviors at different levels of performance are collected. These incidents are then rated and used to develop a scale with behaviorally anchored ratings.

3. **Structure**: The scale typically has a range of 5 to 9 points, with each point on the scale anchored by a behavioral example that exemplifies performance at that level.

4. **Focus**: BARS focuses on specific behaviors that are critical to job success and provides concrete examples of what each level of performance looks like.

5. **Advantages**: It offers clear standards and reduces the subjectivity in performance ratings. It also provides specific feedback to employees about what is expected and how they can improve.

6. **Disadvantages**: Developing a BARS can be time-consuming and costly. It also requires regular updates to remain relevant as job requirements change.

**Behavioral Observation Scales (BOS):**

1. **Definition**: BOS is a performance appraisal method that requires raters to indicate the frequency with which an employee has exhibited certain behaviors on the job.

2. **Development**: Similar to BARS, BOS is developed by identifying key behaviors necessary for job performance. However, instead of anchoring behaviors to a rating, BOS asks raters to observe and record the frequency of these behaviors.

3. **Structure**: The scale is often structured with a range of frequencies, such as "never," "sometimes," "often," and "always," for each behavior.

4. **Focus**: BOS focuses on the frequency of behaviors, providing a quantitative measure of how often an employee demonstrates key job-related behaviors.

5. **Advantages**: BOS is relatively easier to develop and update than BARS. It also provides a more continuous measure of performance, which can be useful for identifying trends over time.

6. **Disadvantages**: BOS may be subject to rater biases, such as leniency or halo effect, as raters may have difficulty accurately recalling the frequency of behaviors. It also may not provide as clear guidance for performance improvement as BARS.

**Comparison:**

- Both BARS and BOS are behavior-based evaluation tools that aim to provide objective measures of an employee's performance.
- BARS provides a qualitative assessment by linking behaviors to descriptive anchors, while BOS offers a quantitative assessment by measuring the frequency of behaviors.
- BARS is more descriptive and can give more detailed feedback, whereas BOS is more focused on the regularity of behavior and can track changes over time.
- BARS can be more useful for developmental feedback, while BOS can be more effective for ongoing performance monitoring.
- Both methods require thorough understanding of job roles and responsibilities, and both can be subject to rater biases if not implemented carefully.

In summary, while BARS and BOS share the goal of assessing employee behavior, they differ in their approach, with BARS providing a more detailed and anchored evaluation and BOS focusing on the frequency of behaviors. The choice between the two methods depends on the specific needs of the organization and the purpose of the performance appraisal.
