Step-by-step explanation:
In a Functional Job Analysis, tasks are rated based on their interaction with data, people, and things. This method helps in understanding the complexities of a job by observing the tasks that are being performed, conducting surveys, and performing interviews with those currently in the position and their supervisors.
The third factor, things, refers to the interaction with physical objects, equipment, machinery, and tools associated with the job. It is part of the systematic process to categorize jobs and understand their requirements thoroughly.
