The economic evaluation of Information System project (the weighting up of investment and expected benefits) has been primarily adressed to answer the question "how to do it". Several interesting propositions have been made in order to make this evaluation ; some of them have been tested. Nevertheless, the practice of evaluation is poor and the 'productivity paradox of Information Technology' is still alive. A new approach of evaluation is proposed. "Why so many enterprises do not evaluate their projects ?" The answer can be found more in the actors' social interests than in new evaluations techniques.
