Difficulties of developing a viable descriptive taxonomy of human performance are described. The authors previous formulation of a functional approach to task description and analysis is reviewed and a useful format consisting of four major dimensions of description is proposed. The rationale for development of a transactional language for describing and analyzing military tasks and duties is presented together with a new system task vocabulary created according to that rationale. The new approach assumes that the human is an information processor.
