Many manufacturing organizations have embraced the philosophy of Simul
taneous Engineering (SE) as a way of working in the highly volatile an
d competitive business world of today. This has occurred because SE me
thodologies are known to have improved quality, reduced time-to-market
, provided greater customer satisfaction, minimized waste, and increas
ed product reliability. Similarly, Business Process Re-engineering (BP
R) has been conducted by numerous business enterprises in recent years
. The objective of BPR is to bring about major breakthroughs in perfor
mance in order to create a sustained competitive advantage. This is at
tained by ensuring maximum customer satisfaction and eliminating nonva
lue-added business activities. Often the issues surrounding the implem
entation of information systems to support SE within a company are con
sidered independently of any ongoing BPR activities. This paper will d
iscuss how a computer-based information system previously developed to
support the Design for Manufacture (DFM) aspect of SE can be extended
to support other business functions with the ultimate aim of achievin
g total Enterprise Integration (EI). A methodology that combines a Com
puter-Aided Engineering (CAE) framework and an information system arch
itecture, to guide this extension through a BPR initiative, will be in
troduced. A case study, showing how the information system was extende
d to provide increased competitiveness of product tenders, is included
to illustrate the proposed methodology.
