• Resumen

  • This paper presents the results of an experimental case study conducted to evaluate the reuse of design information during the conceptual design phase. The goal of this study was to determine the usefulness of design history information and to establish the sneed for providing the conceptual level design information for future use. Five design engineers were given a task of product redesign to satisfy new customer requirements. The scope of the redesign was limited to generating new concept( S) using the old design information. We found that about 50% of the queries made by the subjects were related to the conceptual stage information from the past design effort. We also found that about 70% of the old design information was useful during redesign.
