Example text
4 were primarily generated by analysing the language used to describe what workers did and what got done in 4000 job definitions of the second edition of the Directionary of Occupational Titles. 4 above actually defined virtually all the actions. Fine (1974) notes by selecting one verb from each of the three scales it is possible to describe any task, and, in summary form, the job performed by any worker. 1 (Fine, 1974) is a model of a task statement in functional job analysis and is an explicit expression of a worker action and the expected result of that action.
The worker function scales are defined in very much greater detail than in the USES system, although, as noted, the headings remain the same. In addition, some of the headings are further subdivided into additional levels, A, B, and C. For example, under the heading of Data Function Scale the acts of (1) comparing and (5B) co-ordinating are as follows: 1. 5B. Comparing: selects, sorts, or arranges data, people or things, judging whether their readily observable functional, structural, or compositional characteristics are similar to or different from prescribed standards.
Consensus established by a panel of individuals knowledgeable about the job, such as analysts, subject matter experts, supervisors and incumbents, may also provide evidence of reliability. The validity of a job analysis is rarely questioned and even less frequently ascertained. Rater consensus, including agreement among panel members that a task or set of tasks is required for job performance is a common though erroneous demonstration of validity. Preferred methods for demonstrating validity are (1) retrospective and (2) empirical validity.
