What is a job description PDA?

Understanding the Physical Demands Analysis (PDA)

A Physical Demands Analysis, commonly known as a PDA, is a crucial tool used by employers, occupational therapists, and safety professionals to clearly define the physical requirements of a specific job. It goes beyond a standard job description by detailing exactly what the body does throughout the workday — from lifting and carrying to standing, walking, bending, and reaching.

In workplaces ranging from manufacturing plants to healthcare facilities, knowing the physical demands of a role helps ensure that employees are physically capable of performing their duties safely. For example, a warehouse worker may regularly lift 50 pounds, stand for extended periods, and climb ladders. A PDA documents these actions precisely, allowing employers to match job candidates to roles they can perform without risk of injury.

This analysis isn’t just about preventing strain or workplace injuries — it also supports fair hiring practices, informs return-to-work plans after an injury, and helps design accommodations for employees with limitations. Human resources teams and safety officers often use PDAs to comply with regulations and maintain a healthy, productive workforce.

Think of a PDA as a roadmap of movement. It answers questions like: How much weight is typically lifted? How often does someone kneel or twist? Is prolonged standing required? These specifics help medical professionals assess an individual's ability to meet job demands, especially during pre-employment screenings or disability evaluations.

Ultimately, a well-documented Physical Demands Analysis supports both employee safety and operational efficiency. By clearly outlining what a job physically entails, organizations can foster safer work environments, reduce injury risks, and support long-term employee well-being — one movement at a time.
