This manual provides the information needed to conduct a job analysis and to enter or update job analysis information in the Computerized Task Inventory (COMTASK) database. Chapter I presents the purpose and organization of the manual. The second chapter provides a brief background on the purpose and design of COMTASK, a definition of terms used in COMTASK, and scenarios that illustrate some possible uses of COMTASK. Procedures for conducting a job analysis are detailed in chapter III. Methods of job analysis, the development of a job/task inventory, and administration of the questionnaires are outlined so that the user can follow the processes and enter the results of an analysis into the COMTASK system. Chapter IV gives guidelines for writing duty, task, and equipment statements. Appendixes, amounting to over one-half of the manual, include a sample job/task inventory, input specifications and tips, a sample questionnaire instrument developed from the sample job task inventory, sample Company Consent Forms and Company Demographic Data Forms, addresses of job analyses information, and a workbook supplement that follows the steps in the manual.
