Physical Job Demands Analysis

Demands such as sitting, standing, walking, reaching, bending, and lifting are assigned a frequency rating which is typically documented in a simple checklist to easily see what is required to perform the work. Navisess documents all the tools used for each job, describes the working environment, lists potential hazards, and includes pictures to illustrate common postures. Unlike an office ergonomics evaluation, there is no assessment of risk and no recommendations to reduce such risk. The JDA/PDA simply documents the demands involved with performing the observed job.

What’s the difference between a JDA and a PDA?

The terms JDA (Job Demands Analysis) and PDA (Physical Demands Analysis) are often used interchangeably. However, a PDA usually looks at the physical demands of the job and doesn’t consider cognitive or psycho-social factors where a JDA may consider these factors.

When is a JDA/PDA required?

Employers and businesses often have a catalog of JDAs/PDAs for each of their job positions. If an injured worker is able to return to work with modified duties the JDA for their job can be consulted to see if any of the job tasks exceed restrictions. Similarly, a JDA can be used to make a determination of whether the injured worker can return to a particular job safely. JDAs can also be used to identify heavy or difficult jobs that may be prioritized for ergonomic improvements or changes in the future. If a job is significantly redesigned or a new job is introduced, a new JDA may be needed.
