This paper presents an approach to systems analysis and design called the operations-oriented methodology (OOM). It was developed with the objectives of being comprehensive in terms of scale and detail, easy to understand by a nonexpert and capable of formal analysis. The methodology was tested at seven field sites. The paper describes the fundamentals of OOM, and more particularly focuses on its use of Petri nets and playscript formats, and how these enable us to satisfy our objectives. Limitations of the methodology and future research directions are also mentioned.

The social context of the decision making situation as a factor in determining the success of a decision-making procedure is considered. A simple multiattribute, multialternative decision model is used and extended to the multiple-decision-maker situation by a consensus-building technique. It is shown how the procedure works by applying it to a real-life decision situation involving multiple alternatives, multiple criteria, and multiple decision-makes. The usefulness of a social context as a variable in studies of the decision-making process is pointed out.>

Adequate health-care facilities are seldom available to persons physically remote from population centers. One method of relieving part of the problem is to provide facilities for diagnosing medical problems remotely via some form of communications technology. With this in mind, an experiment was conducted to compare the efficiency and effectiveness of two-way communication systemscolor television, black-and-white television, and hands-free telephone-as an alternative to physical presence consultation. Our results indicate that the taken to complete the diagnostic consultation was essentially the same across all four modes. Furthermore, no significant differences were found among the three remote modes for accuracy of diagnosis and patient management effectiveness, and physical presence consultations were found superior only in discovering secondary medical problems. Nevertheless, the attitudes of both patients and doctors showed a preference for color television over black-and-white television over hands-free telephone.
