The product development literature focuses largely on improving the ef
ficiency and success rates of the development process, while largely n
eglecting the activities that comprise the predevelopment stages. The
result is that little is known about how or why predevelopment practic
es differ among firms. Our study of fifteen firms in Ontario's integra
ted circuit board industry revealed interesting differences in predeve
lopment practices that directly affected the likelihood of new product
success. It was revealed that firm size, age, and R&D intensity were
significant predictors of predevelopment practices. In addition, activ
ities were identified that serve as a prescriptive guide for the succe
ssful development and market launch of new products. Copyright (C) 199
