The purpose of the research is to explore characteristics and design the concept of the knowledge management system that would be able to operate in a loosely coupled system. We used a literature review to determine characteristics of the conceptual design that would fit into the unstable organizational environment. Based on the theoretical insights, we designed the open framework that is capable of adjustments, multilevel designing, it allows integration of statistical methods and supports conversion into the web ontology language. We applied developed concept to a loosely coupled system test case, to achieve better understanding of its capabilities. The solution is appropriate for implementation to analyze knowledge network and process architecture relations in different informal organizational networks, as well as during events where spontaneous cooperation among different types of organizations and individuals is necessary, such as massive natural disasters and other simila events.
