Have you ever written a report on a potential career you are considering? You may have referenced the Dictionary of Occupational Titles(DOT), published by the U.S. Department of Labor or DOL. The Department of Labor recognized that the DOT and the job analysis and categories it used were based on stable workforce requirements and a foundation in manufacturing that didn't apply well to the service based economy and emphasis on technical skills that emerged in the 1990s. They responded by replacing the DOT with the Occupational Information Network, or o-net, in 1998. O-net provides even more information to students needing career research to write reports and to HR professionals who want updated information on job requirements for job analysis.
