Job Specification is a detailed statement outlining the qualifications, skills, experience, and personal attributes required to perform a specific job effectively. It includes educational background, technical or soft skills, physical requirements, and relevant work experience. Unlike a job description, which focuses on duties and responsibilities, a job specification defines the ideal candidate profile. It helps in recruitment, selection, and performance evaluation by setting clear criteria for assessing applicants. A well-crafted job specification ensures better job-person fit, enhances productivity, and supports career development planning.
