Andre, Terence S. and Charlton, Samuel G. (1994): Strategy-to-Task: Human Factors Operational Test and Evaluation at the Task-Level. In: Proceedings of the Human Factors and Ergonomics Society 38th Annual Meeting 1994. pp. 1085-1089.

“Human factors operational test and evaluation (OT&E) at the function/characteristic level has not always provided an appropriate balance of addressing both the needs of the system user and the decision-maker. System users are primarily concerned with the characteristics and capabilities of their system. Acquisition decision-makers, on the other hand, are more concerned with force structure and how potential military systems fit within the national military strategy. Human factors OT&E has traditionally considered the user of the system by testing human factors at a characteristic, rather than mission or operational task-level. In order to address the needs of the decision-maker, OT&E has adopted a strategy-to-task formulation that can have the undesirable side effect of decreasing the visibility of human factors test results. Because human factors measures are considered at the system function/characteristic level, significant human performance/human-machine interface issues are not always visible at the level of higher task elements and missions. Systems which require significant human-in-control or human-in-the-loop operability may lend themselves to consideration at the task-level. Testing human factors at the task-level within the strategy-to-task framework provides both the decision-maker and user with the necessary information to buy and properly operate the system.”
