Ritchie, R. Jay and List, Judith A. (1991): Integrating Usability and Marketing Activities: A Method for Supporting Accelerated Design Strategies. In ACM SIGCHI Bulletin, 23 (4) p. 36.

“Although the practice of user-centered design is advocated in many organizations, engineering management issues may prevent early focus on system usability. Within the usability engineering cycle, practitioners consider task analysis and customer needs assessment a high priority. Market research activities occur early in the process, but usability information is not collected or passed to system developers. To improve and to accelerate the design process and to validate user preference findings, task analysis and market research surveys were performed concurrently during the design validation phase of a data communications product. The basic process steps included: forming a multidisciplinary team, identifying data sources, collecting data via interviews and event record review, transforming data into task models and product opinion matrices, and using the models and matrices to design a sample product. A number of benefits were observed using this method: improved economies of research and analysis time, increased strength of product opinion data, early product improvements, increased customer understanding of the product, and an improved product engineering process.”

Ritchie, R. Jay, Stein, Helen and Coco, Joseph N. (1990): Table-Top Development, Simulation, and Evaluation Environment for Battlefield Information System Concepts. In: D., Woods, and E., Roth, (eds.) Proceedings of the Human Factors Society 34th Annual Meeting 1990, Santa Monica, USA. pp. 632-635.

“A software development environment for prototyping, simulating, and evaluating advanced concepts in US Army battlefield information systems was designed and implemented as a lower cost alternative to complex development and simulation facilities. The workstation-based development environment was designed to evaluate a variety of soldier-machine interface design requirements and specifications, as well as communications and database concepts for future Army vehicle and weapons systems. Using this environment, an armor maneuver control application was implemented, demonstrated, and evaluated in a networked testbed. The application demonstrated the creation and transmission of tactical graphic and text information, automatic message routing, and rapid reconfiguration of the soldier-machine interface. Use of the development environment has demonstrated that battlefield information system prototypes can be quickly and inexpensively simulated and evaluated, and can be used as an adjunct or alternative to other simulation facilities.”

Hockenberger, Roik L. and Ritchie, R. Jay (1988): Design Practice and Application Domain: Primary Factors in Intelligent User-System Interface Design. In: Proceedings of the Human Factors Society 32nd Annual Meeting 1988. pp. 404-408.

“Through the use of AI technology, the potential exists to make revolutionary changes in military command and control. Knowledge based systems can enable a commander and staff to accommodate large amounts of information efficiently and effectively, to generate operations plans rapidly, and thereby allow exploitation of early maneuver opportunities. This paper addresses the issues of applications domain and human factors design practice as they relate to the development of effective user system interfaces for expert systems.”
