Oussama El Khalil HOUSSAINI Thesis defense

Over the last two decades, the purchasing function has undergone a considerable transformation from a support function to a strategic one for the supply hain management. Notably because it has become central in the selection of suppliers, from the process of creating an innovation, it is at the heart of the processes of creating new products in the company. This thesis evaluates the relationship between the characteristics of the purchasing function and the performance of the projects of new product development (NPD). The statistical analysis is based on a sample of 135 respondents, mainly buyers operating in companies in the french west.
The results of the study have provided more insight into the skills required for purchasers in NPD projects. It has also revealed various roles of purchasers, demonstrating their ability to adapt according to the complexity of the project, enabling effective coordination between internal teams and external stakeholders. This research presents limitations, such as the lack of supplier perspectives and its exclusive focus on the western region of france.
