What is the first HR tool to use for identifying predictors of success in a job?

The first HR tool to use for identifying predictors of success in a job is job analysis. Job analysis involves systematically gathering, examining, and organizing information about a job's content, requirements, and context. It helps to identify the skills, knowledge, and abilities necessary for successful performance in a given role.

Job specifications and job descriptions are integral parts of job analysis but are derived from it. Job specifications outline the qualifications and competencies needed for a job, while job descriptions provide an overview of the responsibilities and duties associated with a job. Job evaluation, on the other hand, focuses on determining the relative worth of jobs within an organization for purposes of compensation and is not primarily concerned with identifying success predictors.

Job analysis stands at the forefront as it helps to create a foundation for effective recruitment, selection, and performance management strategies by identifying the key attributes that predict success in a job.
