PLM adoption can be a source of competitiveness and sustainability for SMEs. In the other hand, the introduction of new ICT (Information and communication technologies) technologies, such PLM, is a complex process that involves challenging the existing organization, not only in terms of information flow but also the human resources management and OEM/Suppliers relationship level. As seen in literature review, there are a number of factors that facilitate the adoption of ICT technology, but we also identified a number of obstacles that will need to act as the adoption takes place. The paper focused on issues regarding the ICT adoption, especially PLM solutions by SMEs. Based on investigation, this paper proposes a mathematical model of PLM adoption.
