If there is one subject in this series of calls on PNI applications that can spark a controversy, it is the forthcoming one on Knowledge Management and Organisational Learning. The KM notion is probably in the top 3 of most abused terms in the recent history of management theory and practice. It has lost most of its meaning, just as happened to sustainability, impact assessment and complexity. In this blog I try to make a modest start to polishing it up a bit. I hope it helps to continue that process in our call next Wednesday.
