The purpose of this case study is to understand the importance of job analysis for an effective work delivery and most importantly an appropriate appraisal system. While the outcome of any job analysis has two main components - job description and job specification - its understanding has far reaching implications in an organizational context in general and HR Departments in particular. Describing the HR issues faced by Anoop Singh, Aditya Sharma, Pooja Thakur and Sarika Bakshi (AAPS) - professionals working with different organizations - the case study explains how the four faced problems due to missing or inappropriate job analysis. Did all the problems arise due to erroneous job analysis? The case study shows the impact of job analysis on important HR decisions such as recruitment and selection, performance appraisal, job evaluation (wage and salary decisions) and the training requirements. This case study can be used to highlight how a seemingly theoretical and an unimportant HR practice like job analysis could deeply impact several other allied HR decisions. This case study can be suitably used to teach the concept of Job Analysis and the allied concepts (like job description, job specification and performance appraisal) in Human Resource Management course.
