The demands of a job and its potential modifiability must be known in order to assess the employability of a functionally limited person. A job analysis includes:

1. Purpose
2. Hiring requirements
3. Salary
4. Tasks and elements (beginning with an action verb)
5. Physical demands
6. Working conditions
7. Tools and machines used
8. Specific skills
9. Aptitudes
10. Temperament
11. Interpersonal interactions
12. Unscheduled demands
13. Architectural barriers

The analysis is constructed through observations and interviews with workers and employers. It is necessary in order to make a feasible job placement. Sometimes adaptive aids or job modifications will allow a match between client and job.
