Boundary, purpose, and values in work-domain models: Models of naval command and control

Abstract:

This paper presents an application' of work-domain analysis (WDA) to the domain of the command and control of a multipurpose naval frigate - the Canadian Halifax Class frigate. This represents an application of this approach to a real system and, to the authors' knowledge, is the most extensive WDA of a naval work domain. In particular, and in contrast to other applications of cognitive work analysis, the authors extended the basic WDA framework to handle a multipurpose, loosely bound work domain. In addition, the naval domain is value driven, and this affects naval decision making. Values were incorporated as a social organizational analysis into the work-domain model and were represented as a type of soft constraint. A total of 38 submodels of the work domain were developed, whose primary models are discussed in this paper. From these models, 132 information requirements were extracted, substantiating that WDA is a worthwhile technique for supporting interface design. This paper makes a theoretical contribution by extending the WDA framework and a practical contribution by demonstrating the usefulness of the framework in a real design context. This paper concentrates on presenting WDA as a process, not as a finished product, showing intermediate levels of models and the design requirements that can be extracted from the early stages of the WDA. © 2005 IEEE.
