A job demands analysis is completed through an onsite assessment to observe how a specific job is done at a workplace.

The essential and non-essential job components are identified to determine the essential skills and abilities an employee requires to successfully do the job. The physical, cognitive, psychosocial and behavioural demands of  the job are identified as part of this assessment.  

A job demands analysis is used to gain an objective and clear list of the job demands, which can then be used to determine if an employee has the skills and abilities to complete these demands. This type of assessment is helpful in determining what an employee will need to focus on in their rehabilitation to build their capacity to meet the specific job demands. A job demands analysis can also be an important component of an overall assessment to determine an employee’s fitness to return to a specific role.
