Concurrent engineering tools: are the human issues being ignored?

Abstract

Concurrent engineering (CE) tools are intended to increase the concurrency of multidisciplinary design by integrating various enabling technologies such as computer-aided design, computer-aided manufacturing, group decision support systems, expert systems, and communication networks. If the long term viability of CE depends on effectively developing and deploying CE tools, the assumptions about how CE design tasks are most successfully performed and the roles of tools in facilitating that work should be carefully reviewed. This paper identifies the human factors assumptions made by the CE tool development community and compares them to conclusions drawn from existing literature on the role of technologies in performing technical work. This comparison suggests that the assumptions made by the CE tool development community are likely to inhibit CE tools from successfully enabling the CE process. Recommendations for remedying this state of affairs are offered in the form of restated assumptions that are consistent with documented behaviors of people using similar technologies and potential development strategies for CE tool developers.
