Computer-aided engineering and computer-aided production management are seen as vital components of computer-integrated manufacturing. But do these technologies complement or conflict#x003F; This article sets out the arguments and looks at the supporting evidence.

The tasks confronting CAPM systems and the costs involved, both operational and capital, are also covered. Retrospective improvements and implementation problems are discussed.
