Final answer:
A receptionist's job can be effectively analyzed using direct observation because their tasks are visible and occur in a live, interactive setting. Unlike roles like software development, the receptionist's job involves direct interactions that can be observed and assessed in real-time.
Step-by-step explanation:
The job that could be analyzed effectively using direct observation is C) Receptionist. This position involves tasks and interactions that are visible and can be observed in a live setting, such as greeting visitors, answering phones, and managing schedules. Direct observation allows an analyst to see how the receptionist interacts with others, manages their workflow, and uses physical tools of the trade, such as a computer or a telephone. In comparison, jobs like software development and graphic design often require in-depth knowledge of the processes that may not be visible on the surface level, making them less ideal for analysis through direct observation alone.
Observation is a key technique for job analysis as it enables an understanding of the skills and behaviors that are apparent while an employee is performing their job. It is particularly useful for understanding the fine details of a job, such as the ergonomics of a workstation, which would interest a human factors psychologist.
