Previous studies (Bhuiyan, 2001; Bhuiyan et al., 2003; Jaafar, 2001) used stochastic computer models to study concurrent engineering (CE) processes. This thesis used the same models, but modified the two main mechanisms used in CE, that is, functional interaction and overlap, in order to better understand how they contribute to process performance, i.e., how they affect product development effort and span time. The present study used more realistic development processes over previous research in addition to using the same uncertainty conditions, rework, learning, and communication techniques. Simulation results of the updated models were discussed in comparison to the baseline models in terms of effort versus span time and effort distribution during the process versus span time. / Research outcomes indicated that the use of CE was beneficial as long as the uncertainty of information during product development was moderate to low. When uncertainty was high, sequential engineering was best. Several cases were demonstrated. / The distribution of effort during product development was studied and it showed that processes should be designed to avert rework due to design versions (complete redesign of the product) and should emphasize churn (redesign in small steps during teamwork).
