The past years have seen growing investments in the area of PLM by several industries. In today’s industrial production, PLM is an essential tool to cope with the challenges of more demanding global competition and ever-shortening product lifecycles. Complex products require collaboration of large specialist networks. Knowledge Management (KM) can be apprehended in two manners: the defensive manner builds the stock of knowledge to face the departures of personnel, or, the offensive manner sees in the knowledge development an advisability to generate new products. The link between PLM and KM is interesting as it can help answering “on field” problems. In this paper we first make a state of the art of knowledge and KM in a PLM context. Then we propose a methodology to deploy KM in the particular case of a software integrator. Finally, we propose an experimental protocol that will allow us to improve a tool demonstrator in an agile way.
