This paper is based on the definition of a network-centric structure as one which enables members of an organisation to create and leverage information to increase competitive advantage through the joint efforts of creative individuals and independent teams. While the technical components of this environment are enabling, the organisational and behavioural components generate value as traditionally competitive workers strive to cooperate in self-directed, distributed teams. Many organisations are now complex hybrids of hierarchical and network-centric configurations and there is a need to increase our understanding of their human and informational aspects. Due to its suitability for managing complexity without reducing it to a simpler form, this paper concerns the use of the holistic and dynamic technique of systems modelling for research in this area. The use of stock and flow systems modelling is described and examples of its application to realistic network-centric phenomena, incorporating human and informational elements, are presented. Development of these models is not easy, neither is it an exact science. This approach does however have the potential to visualise and manipulate an interconnected set of human and informational elements to enhance understanding of the complex network-centric paradigm.
