This paper presents the findings of part of a 30 month investigation, conducted to better understand the persistent failure of management practitioners to fund potentially disruptive innovations.

It was found that funding decisions are mainly constrained by mental not physical processes. Organisations wishing to pursue disruptive innovations can challenge psychological attachments to incrementalism, and overcome the funding barrier, with a holistic understanding delivered through graphical portfolio tools
