Duringproduct design, over 80% of engineeringchanges areneededbecausedesigned
parts cannotbemanufacturedor assembled
(Stevens, 2001). Most of thedesign errors are
due to lack of communicationbetween thedesign
team andmanufacturingexperts. To reduce communicationproblems and, thereby, increaseproduct quality andreduceproduction costs, industry
hasturnedto concurrent andcollaborative engineeringmethods(Prasad, 1996). However, in
today’s global market, designers andmanufacturers are often geographically separated. Thus,
designers, manufacturers, andsuppliers need
powerful communication toolsso they can
exchangedesign information effectively (Jones,
Schwemin, Dorneich, & Dunmire, 2000).
