This paper discusses the concept of opportunistic collaboration within the emerging mobile knowledge society. The paper illustrates how opportunistic collaboration can be applied to the areas of learning and earning by demonstrating how to transform a traditional unemployment agency into an Opportunistic Collaboration Agency based on an entrepreneurial supply-support network structured in the form of a prosumer manifold. The OCA pattern provides ways to capture the dynamics of entrepreneurial work-relations in the emerging ‘work-portfolio society’, increase the transparency of the entire value chain of economic activities, and create prosumer value loops that can support multi-dimensional bartering and increase the opportunities for marginalized groups of people to create value together. The paper ends by demonstrating how to use the OCA pattern to transform a traditional educational institution into an Opportunistic Learning Activity Broker that could help to bridge the gap between formal and informal learning.
