Job Demands Analysis & Physical Demands Analysis
Our comprehensive analyses capture all the necessary detail to assist stakeholders with their decisions around job modifications, supporting employees on the job and return to work programs.
What’s the difference between a JDA & PDA?
The terms JDA (Job Demands Analysis) and PDA (Physical Demands Analysis) are often used interchangeably, although technically a PDA only looks at the physical demands of the job and doesn’t consider cognitive or psycho-social factors.
What is it?
A Job Demands Analysis is a detailed, objective description of the physical and psycho-social aspects of a particular job. Demands such as sitting, standing, walking, reaching, bending and lifting are assigned a frequency rating, typically documented in a simple checklist so readers can easily see what is required to perform the work. MoveSafe documents tools used, describes the environment and potential hazards, and includes pictures to illustrate common postures. Unlike an ergonomics evaluation, there is no assessment of risk in a JDA/PDA and there are no recommendations to reduce risk. The JDA/PDA simply documents the demands involved with performing the observed job.
Why Do a JDA or PDA?
Clients often have a catalogue of JDAs/PDAs for each of their jobs. If an injured worker is able to return to work with modified duties the JDA can be consulted to see if any of the job tasks exceed restrictions. Similarly, the JDA can be used by a healthcare provider who may need 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.
I really appreciate your efforts, and I agree fully with all the concepts you teach. There is nothing more that I would love, than to get the culture of everyone here in woodlands to be proactive about preparing yourself physically for the job – office or fieldwork…it’s the root to many of the injuries we see.
