WHY IS JOB ANALYSIS IMPORTANT FOR SELECTION?

1.       Identification of the most important duties and responsibilities of the position to be filled. In other words, what is the main purpose or primary reason the position exists? One source of this information is the current official position description (PD). Another source is information from the individual who most recently occupied the position, gathered during an exit interview or from other individuals currently occupying the position.

2.      Identification of knowledge, skills, abilities, competencies and behaviors required to accomplish each job duty or responsibility. It is important to include the skill level needed for each job duty and the quality level that will be used to measure each one. Each item must be ratable, meaning it can be measured and/or observed.
