This paper is an account of the theoretical and practical underpinnings of the Decision-Proposal Modification Coding System (DPM), which allows researchers to study more accurately the many aspects of group decision making in organizations. Following an introduction that reviews and supports arguments for process-oriented research on decision…

An information system can be viewed as a symbiotic relation between the users of the system and the system's hardware, software, and data resources. Ideally, performance evaluation of these systems should be based on the achievement of user based criteria while concurrently minimizing resource costs. Current evaluation technologies concentrate on…

The main purpose of the research reported in this document was to discover whether controlled experiments can be conducted on the relations between people and the complex computing systems which they use. Three increasingly complex experiments were designed to test the effect of varying delays of computer response on the number of commands issues…
