In presence of rapid development of information and communications technology (ICT) able to increase data processing, much more data can be stored, used and/or mediated and disseminated. Technology for extracting and assembling data into valuable information set has become of huge importance nowadays. Information and knowledge become a resource of strategic importance in complex systems, both business and military. On the other hand the question of credibility of the collected data arises: complex systems have to deal with an increasing access to information with less knowledge about their origins and their quality. Due to this lack of information on information, contemporary organizations suffer from organizational indifference: There is a constant presence of the risk that multitude of voices in an organization’s environment turns into an unintelligible cacophony or even white noise [16]. In this paper the ways and means for achieving information superiority in complex systems are examined, with special emphasis to military systems.  As a result, two approaches within the military domain are presented: Network Enabled Capability (NEC) and Multilateral Interoperability Programme (MIP). Firstly, if implemented correctly those enable technical, semantic and process interoperability. Secondly, consistent appliance of proposed approaches leads to possible achievement of information superiority (IS).
