A job analysis is the act of collecting the information one would need to determine what is needed to complete a job and the steps involved in that completion. To effectively analyze a job one would need to know how long it takes to complete a job, what specific tasks are needed to achieve the goals, what are the goals and what type of employee might fit that need. A job description, on the other hand, describes, or lists the specific requirements for a specific job. The employee would be given the job description so they would know exactly what is expected of them. They would be told the goals, the work hours, the required tasks to complete and how they would be compensated. The job design adds together the needs of the company with the needs of the employee. The design is what makes the product successful and the worker more efficient. The person in charge of the job design would be responsible for the company needs of hiring, training and employee review.
"Job analysis is the term used to describe the process of analyzing a job or occupation into its various components, that is, organizational structure, work activities, and informational content."
Job analysis is one of the preliminary activity necessary for preparing a proper job description. However job analysis may be used for other purposes also.
A job description is defined by BS 32207 as a written outline of the main tasks of a job. It is a written statement covering the essential features of a job, including its purpose, duties, skill requirements and a set of duties and responsibilities that indicate the content of the job in detail. One obvious use of job description is for clarifying duties and responsibilities. Other uses of job description include job evaluation and merit rating, and preparation of job specifications.
Job analysis is a systematic process of analyzing a job for identifying job contents, leading to job description, job specification, and job evaluation.It involves determination of the requirements of the job through detailed observation and evaluation of work performed, facilities required, conditions of work, and the qualifications required of the worker. BS defines job analysis as the determination of essential characteristics of a job in order to produce a job specification.
Job evaluation helps in design of jobs that enable achievement of organizational goals and objectives effectively and efficiently. It is also used to design jobs that lead to better involvement and job satisfaction for people who perform the jobs.
