Presently, there is a great need for methodologies and reference models to assist and guide the creation and operation of various types of enterprises, including Collaborative Networked Organisations (CNO). The efforts to fulfil this need can be greatly assisted by a meta-methodology integrating current and future CNO creation and operation knowledge. This paper presents a milestone in an iterative and reflective action research aiming to demonstrate the feasibility of a CNO life cycle meta-methodology. This is done by describing a field experiment / case study and subsequent reflections leading to the refinement and extension of the proposed meta-methodology.
