ABSTRACT
It is well documented that co-production lacks a universal definition that can be used for all settings the concept is applied in. In the absence of such a definition, many practitioners have resorted to defining co-production based on its key principles. Up until 1995, co-production had no principles underpinning it. However, from the latter half of the 1990s onwards, Edgar Cahn proceeded to create four key principles that underpinned co-production. These are: recognising people as assets, valuing work differently, promoting reciprocity and building social capital. This chapter builds on Cahn's work by providing the results of a comprehensive search of the literature and subsequent synthesis which took place in order to identify if Cahn's four principles are still relevant today and also if there are any new principles that need to be added. The chapter presents the results of this synthesis. From which, recommendations are made for future synthesis conducted in this area.
