24 Consulting Organisational Change Cooperation – Challenges, Issues and Solution s in Theory and PracticeJOURNAL OF MANAGEMENT AND CHANGE No 29 2012 Abstract The cooperation capacity of public organiza- tions and profit companies is an increasingly valuable resource. Cooperation partners come from profit and non-profit organizations and from organizations in the public domain, and all are subject to a financial and legal context. Coming from such completely different work- ing contexts, logics and cultures, the potential partner organizations provide services paral- lel to each other (many times in a competitive relationship). How can those partners jointly “co-produce” benefits through cooperation? Within such an environment, a shared case for action needs to take place, generating enough “energy” for the key players to embark on such a cooperative adventure. How is it possible to initiate such a process? At the end of a cooperative change process, it is vital that the cooperation is fully developed and established. How should the cooperation project be designed and implemented so that cooperation can continue? This article discusses these issues and chal- lenges using a case study. From the consultants’ perspective, the article explores the question of how collaborative change processes can be successfully managed and consulted through concrete interventions (e.g. organizational design, process design, settings, etc.). From a scientific perspective, the article tries to show which challenges and issues have to be con- sidered. In this interaction between practical action and theoretical ref lection, the article specifi- cally describes what happened in the change process, but also generalizes aspects that offer theoretical insights into OD change processes in inter- and trans-organizational cooperation.
