Phases amont de l'innovation : proposition d'une démarche d'analyse de besoin et d'évaluation de l'acceptabilité d'un produit

Abstract : Nowadays, companies must offer new products continuously and take into consideration new available technologies in order to satisfy more and more exigent and diversified customers. Therefore, it is essential for a company to know what are the needs of the stakeholders interested in its product. The objective of this PhD work is to propose a new method to analyze the need in order to improve the new product definition process in a firm. This tool is a part of a methodology for innovative project management and it is useful before the elaboration of the specification of the new product. The proposed method has four phases: description of the stakeholders environment by the RARe technique (Resources-Activities- Results), determination of needs by the realization of four types of operations on the stakeholder's resources then evaluation and classification of needs according to the Kano model and finally comparison of several products concepts. To achieve this method, a bibliographical work on the notion of need was realized. This bibliographical research also allowed us to define the specifications of a new method for need analysis. Hence, the choice of the RARe method was justified because it is based on the observation of the stakeholders' activities. To classify their needs, we used the model of Kano, which distinguishes various existing needs: basic, one dimensional, attractive and neutral. We worked out a calculation of indicators by means of a matrix formulation allowing to classify needs and to compare concepts of products. This method thus constitutes a decision-making tool at the beginning of the conception process
