Job Analysis

Job analysis is the systematic process of collecting, documenting, and analyzing information about the duties, responsibilities, required skills, working conditions, and outcomes of a specific job. It forms the foundation for HR activities including job descriptions, hiring criteria, performance standards, training design, and compensation structures.

Common methods include: structured interviews with job incumbents and supervisors, observation of employees performing the job, work diary or log analysis, questionnaires and surveys (e.g., Position Analysis Questionnaire), focus groups, critical incident technique (collecting examples of effective/ineffective behavior), and analysis of existing job documentation.

Task-oriented analysis focuses on what the job involves : the specific duties and activities performed. Worker-oriented analysis focuses on the knowledge, skills, abilities, and other characteristics (KSAOs) a person needs to perform the job effectively. Most modern job analyses combine both approaches to capture full job requirements.

Job analysis defines the essential functions and required competencies for a role, which then inform job descriptions, interview question development, assessment selection, and candidate evaluation criteria. Using job analysis to anchor hiring decisions reduces bias and improves the validity and legal defensibility of selection processes.

Under US employment law, particularly the ADA and Title VII, organizations must be able to demonstrate that their hiring criteria are job-related and consistent with business necessity. A documented job analysis provides this evidentiary foundation, protecting organizations against discrimination claims and supporting reasonable accommodation determinations.

Job analyses should be reviewed when: significant role changes occur (new technology, restructuring), performance issues suggest misalignment between job design and expectations, compensation surveys require updated job content data, or at minimum every 3-5 years. Technology-driven roles may require more frequent updates.
