The growth of information technology within organizations has created the need for organizational evolution. These evolutions particularly concern the Information Technology department (IT department) which develops and manages the IT programs and infrastructures within the organization. Not only the evolution of IT leads to a re-assessment of individual knowledge and expertise within the IT department but it also has an impact on the collective competencies necessary to cooperate with internal customers, suppliers and consultants. This article presents the organizational framework implemented within the IT department of a French car manufacturer in order to acquire and better share knowledge. We distinguish capitalization tools which, by creating standardized procedures and references, contribute to the collective memory and socialization devices which produce tacit and fragmented knowledge. Finally we identify a number of difficulties linked to the technical, professional and organizational rules of the IT department.
