Marketing, ergonomie et ingénierie système: jouer la complémentarité pour innover

Marketing, human factors and systems engineering are different disciplines which apply different profiles and skills. Marketing is taught by business schools, while very few engineering schools teach it. The latter dedicate much time to systems engineering and many others engineering's. Human factors is anchored within medicine, humanities and social sciences. It is a little part of an engineer curriculum, while, since few years, human factors and human-computer interaction are taught within engineering schools. Nowadays, conferences and volunteers meet human factors and systems engineering, such as ErgoIA (ErgoIA 2004, ErgoIA 2006, ErgoIA 2008 [22]) or AFIS' human factors technical committee. The aim of this article is to show complementarily between these disciplines to design systems which satisfy consumers and users' needs, particularly in the business to consumer context. At first this article presents main processes of these disciplines and how these processes should be coordinated together. Then, it demonstrates how marketing and human factors processes' outputs structure system architecture design. This article finishes with a case study applying the proposed approach, in the domain of health and care service systems.
