Designed as a procedural manual for occupational analysts, this guide explains the job analysis approach used by the United States Employment Service (USES) system. Part 1 covers methodology and applications. Five chapters define job analysis terms and discuss major principles and applications of job analysis, conducting job analysis studies, writing job descriptions, organization charts, and workflow charts. Part 2 describes the job analysis components of work performed and worker characteristics. The three chapters on work performed address these components: worker functions, work fields, and materials, products, subject matter, and services. Seven chapters on worker characteristics focus on these components: general educational development, job training time and specific vocational preparation, aptitudes, interests, temperaments, physical demands, and environmental conditions. Part 3 is devoted to job analysis forms and procedures and their use within the USES. The staffing table, job analysis report, and narrative report are discussed, and samples/examples are provided. Appendixes include a job analysis study flowchart, task analysis, examples of job descriptions, and a workflow chart. A 39-page bibliography and an index are provided. (YLB)
