Proposition d'indicateurs produit, processus, organisation pour assurer l'adéquation entre l'expression d'un besoin et les spécifications du produit.

Taken decisions very early during design cycle generate most of the costs and have an influence on time limits. Using representation models allows experts to exchange relevant project data but, for persons in charge of projects, it is not easy to decide from these various and often heterogeneous data. Defining indicators aims to help decision-makers in their choices. What distinguishes the indicators here given is their taking into account not only technical aspects (i.e. related to the product). Aspects related to processes and organization are considered in order to take the project in its full complexity. Using such indicators enables finally to obtain a product respecting the expression of the need and ensuring the company perenniality.
