Knowledge Management (KM) adoption theory, research and practice appears to have its primary foundations in generic organisational change theory. Recent research into KM adoption by individuals indicates diffusion of innovation theory may better explain individual adoption. This paper presents the Extended KM Adoption (EKMA) model and proposed research to test and further develop this model. The EKMA is a research framework which recognises the changing dynamics at play across four phases in the lifecycle of KM adoption by organisations. The EKMA model builds on research into the factors that influence the volitional adoption by individuals of KM.
