A Physical Demands Analysis, sometimes called a Job Demands Analysis, is a thorough evaluation of the physical, cognitive, and sensory demands of a particular job, as well as documentation of environmental factors. Conducting a PDA is essential for workplace ergonomics, occupational health, and ensuring compliance with labor regulations. A job differs from an occupation in that job demands can vary from employer to employer for the same occupation. The PDA 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). Additionally, it plays a critical role in workforce planning and employee safety. Moreover, they are useful in identifying limitations when orchestrating Graduated Return to Work plans for injured workers. A comprehensive PDA also aids in identifying safety concerns, enhancing workplace productivity, and developing new, more efficient and safer procedures.
