In situations where multiple new jobs are created and recruited for the first time, or the nature of a job has substantially changed, a job analysis might be undertaken to document the knowledge, skills, abilities and other characteristics required or sought for the job. From these the relevant information is captured in documents such as job descriptions and job specifications. Often, a company already has job descriptions for existing positions. Where already drawn up, these documents may require review and updating to reflect current requirements. Prior to the recruitment stage, a person specification should be finalized to provide the recruiters with the project's requirements and objectives.
