There are many models for how performance appraisals should be performed and what should be included in the performance appraisal process (Pulakos, 2004). Some organizations rely solely on a supervisor reporting observed job-related outcomes and behaviors; others require assessments from multiple sources (e.g., peers, customers, subordinates, supervisor, and self) depending on the nature of the job. Molding a performance appraisal process to fit a job and the needs of both the employer and the employee is important if the desired outcomes for both are to be achieved. Therefore, it is important to understand not only for what the appraisal is to be used, but also what its individual components add to the decision-making process (Pulakos, 2004).For this Discussion, select a performance appraisal instrument or a performance appraisal process.Post a description of the performance appraisal instrument or performance appraisal process you selected. Then, provide a rationale for how the use of a performance model might improve your instrument or process. Explain how the use of a performance model may influence employer as well as employee outcomes in the performance appraisal process. Provide concrete examples and citations from the Learning Resources and current literature to support your post.
