Final answer:
The use of job analysis to assign duties and identify overlap is most closely related to 'Job Description,' which encapsulates both task and worker-oriented details to outline a job's duties and required qualifications.
Step-by-step explanation:
Using job analysis to ensure that all of the duties that need to be done have actually been assigned and for identifying areas of overlap within duties is most closely related to d) Job Description. Job analysis involves observing and interviewing current employees to determine the skills required for a job. This process yields detailed information for both task-oriented and worker-oriented job analysis. Task-oriented analysis focuses on the specific tasks of a job, while worker-oriented analysis identifies the characteristics needed to perform the job effectively. A job description synthesizes this analysis into a comprehensive list of duties and qualifications needed for a position, making it a crucial tool for ensuring all responsibilities are covered and delineating the scope of positions to avoid overlap.
