This paper addresses the need for correct and consistent use of concepts and terms in engineering environments. It provides guidance on how to formulate a corporate terminology policy as a pre-requisite for managing corporate language, designing and implementing a terminology process, and eventually writing definitions and creating new terms. The strategy presented in this paper follows the elcat model, an innovative e-learning initiative that focusses on content development of terminology management modules for the automotive industries. The authors suggest that the role of terminology management is to bring some order to support consistent and more precise language adoption for a period of time. Effective medium to long term terminology management is thereafter enabled through the introduction of a terminology change management procedure.
