ABSTRACT
The methods to be reported in this paper are being developed to meet the prototyping needs of new military C4i (Command Control Communications and Computers) systems. Part 1 of this paper presents a concept for a structured means to predict SA. The concept is based on integrating existing methods to enable the SA present in the system to be compared with the SA required by the task. Part 2 of this paper reports on several methodological enhancements to existing SA measurement techniques. Having made the comparison between system and task SA the aim is to more objectively measure individual SA resulting from any match or miss-match. Between them the refined approaches could help to predict prominent sources of potential SA errors before new C4i systems are built, and to accurately measure resultant SA once they are.
