When does a conceptual framework become a theory? Reflections from an accidental theorist.

In this short paper I reflect on the application of a program logic modeling approach to visualizing evaluation theory as it relates to practical participatory evaluation (PPE). The work of Hansen, Alkin and associates presented in this volume is well-thought out, carefully done, rigorous, and important. I found that their application of the approach resonated well with my understanding of PPE with a few notable exceptions. Specifically, the essence of the partnership aspect of the approach was underemphasized as was stakeholders' role in augmenting the credibility of evaluation findings and PPEs contribution to conceptual use. I then reminisce about the development and evolution of the participatory evaluation framework that we have been working with for so many years. I raise the point that we think of it as a theoretical framework to bound inquiry, not as an evaluation theory per se, which raises an interesting question: when does a theoretical framework become a theory?
