A Physical Demands Analysis, sometimes called a Job Demands Analysis, is a thorough evaluation of the the physical, cognitive, and sensory demands of a particular job, as well as documentation of environmental factors. A job differs from an occupation in that job demands can vary from employer to employer for the same occupation. The Physical Demands Analysis is useful in identifying key attributes required for job candidates, which can be assessed during Post Employment Offer Testing (POET) or a Functional Capacity Evaluation (FCE). Moreover, they are useful in identifying limitations when orchestrating Graduated Return to Work plans for injured workers. They can also help identify safety concerns and lead to new more efficient and safer procedures.
