Knowledge management based on symmetric incentives is rarely found in literature. A knowledge exchange model relies upon a double loop knowledge conversion with symmetric incentives in a network. The model merges specific knowledge with knowledge from other actors into a decision support system specific for each actor in the network in recognition of actor role differences. The article analyses the conditions for the model to generate symmetric incentives between different actor roles. The model is proposed for business networks like supply chains and networks like replacement, maintenance and services industries.
