1) Jobanalysis involves the systematic collection of all information about a job to determine its requirements. This information should be obtained from a number of sources, such as the person performing the task, the immediate supervisor, observation by work-study specialists, and labor union representatives, in unionized companies. From the job analysis, a job description is prepared. The job description identifies the authority of the task, its location in the company, and the activities and major responsibilities of the job. Whereas the job description describes the task, the job specification focuses on people. It outlines the personal qualifications essential for completing the task, such as education, experience, mental and visual abilities; the supervisory responsibility for the position; the physical requirements of the task; accountability; the complexity of duties; working conditions; and work relations expected with others. This information is critical for human resource managers as they assist line manages in completing the staffing process.
