Job Descriptionとは何ですか？

A job description is a formal written summary of a position within an organization that communicates what the role does, what qualifications are required, who it reports to, and where it fits in the organizational structure. A complete job description typically includes the job title, department, reporting relationship, FLSA classification (exempt or non-exempt), employment type (full-time, part-time, temporary), a summary of the role's purpose, a list of essential functions and responsibilities, required qualifications (education, experience, skills, certifications), preferred qualifications, physical demands or working conditions if applicable, and compensation range in jurisdictions where pay transparency is required.

Job descriptions serve multiple functions across the employee lifecycle. During recruiting, they define the candidate profile and set expectations for applicants — affecting both the quality and diversity of applicant pools. Clear, inclusive language attracts a broader range of candidates; jargon-heavy or unnecessarily restrictive language can screen out qualified candidates unnecessarily. During onboarding, the job description anchors discussions about role expectations and early objectives. During performance management, it provides the baseline against which performance is evaluated. In legal proceedings, it is a key piece of evidence in disputes about what the employee was hired to do, whether a position is truly exempt from overtime, and whether a termination or disciplinary action was appropriate.
