This paper provides a taxonomy of knowledge management systems (KMSs) in small supply firms and identifies relevant tools and practices supporting firms in the different phases of knowledge management process. Based on a field analysis that involved 61 small suppliers operating in high-tech industries, the paper highlights that suppliers are generally inclined to use not updated KMSs instead of the newer ones, which are also cheaper and user friendly. This gap shows the difficulties that small suppliers have to be responsive to the rapid technological changes. The field analysis also points out that small suppliers investigated perceive the knowledge management mainly as an issue of knowledge transfer and knowledge storage while appear to be neglected the phase of knowledge creation. Moreover, the paper highlights a misalignment between the intensity of use of knowledge management practices, that support the phase of knowledge creation, and knowledge management tools that should support such practices.
