The paper describes the findings and approach of Ex NEAR HORIZONS, which as part of a series of trials, aimed to explore the performance characteristics and potential operational benefits of a number of technology inserts for the UK Digitization Programme. Although the exercise contained 5 discrete options (hypotheses) for improvement in Command, Control, Communications, Computing and Information (C4I) this paper explores only two of these: a web-based approach and the provision of technology to support distributed and co-located collaborative team working. Despite the commercial world moving towards an information exchange model based on publish and subscribe, the trial found that, although the concept was well received, the implications for changes in organsiation and process were substantial. When working collaboratively in a distributed environment, the findings indicate difficulties in gaining an initial shared understanding of the situation and to exercise command. The participants were a wide range of regular British Army Officers, not only to provide broad views on current military benefits but also to move away from the traditional trials, which tend to expose a single HQ, with prescriptive processes and organizations to the technology. The innovative trial was considered to have been very successful, gathering a considerable body of valuable data and identifying clear paths for exploitation of information technologies to support the military decision- maker. The paper extrapolates the findings of the trial to provide comment on the potential difficulties facing the concept of Network Centric Warfare.
