Current research on and practices of post-project reviews (PPR) are ad hoc in nature. This paper introduces an organizational memory (OM) approach to evaluating the knowledge dissemination function of post-project reviews in a systematic and quantitative way. The approach is based on a network topology of organizational memory and its structural changes during PPRs (i.e., network dynamics). We try to associate PPRs and OM in the sense that both facilitate organizational learning (OL) through knowledge management (KM). At the end of the paper, some suggestions on improving the practice and research of PPRs are given.
