With increased market pressures now imposed on companies there is a greater
requirement for information and knowledge to be considered as fundamental
resources; the need to rapidly provide high quality products of high perfor
mance and reliability is forcing companies to change the way in which they
manage them. The goal of this paper is to identify the pertinent research i
ssues that will need to be considered in order for knowledge (and informati
on) to be successfully integrated into future product development. This wil
l be achieved by presenting the key findings from empirical and simulation
studies of information and knowledge access in engineering design, within a
number of different design activities. In particular, this will show the e
xtent to which engineers rely on their personal knowledge. (C) 1998 Elsevie
