Job Analysis is the first step in doing this, and it’s a key technique for managing job overload – an important source of stress. The main purposes of conducting job analysis is to prepare job description and job specification which in turn helps to hire the right quality of workforce into the organization. A well put together job description is a good business investment because it can be used to support HR functions: recruitment, selection, training, work plans, compensation, performance reviews and legal defense. Job descriptions explain the key responsibilities of the actual position, reporting relationships and work environment.
