Collaboration is often cited as fundamental to systemic change efforts. This paper presents a process-based model for collaboration, which can be adopted as part of systemic, generative change. Schools attempting to create a collaborative culture often encounter the following problems: collaborators who fail to translate their experiences to others; models that do not match experience; and participants who engage in organizational politics. The proposed model is grounded in social processes, and identifies four domains of collaboration: engagement, negotiation, performance, and assessment/evaluation. Engagement is the process through which the group or individual develops an understanding of the problem. Negotiation refers to the development of an action plan in which objectives are clarified and the meaning of success is defined. Performance refers to the actual work done by the group. Assessment entails systematic reflection of outcomes and processes. The model attempts to demystify the process by not specifying a set path to be adhered to by participants. (LMI)
