The vision of network-centric operations is to increase operational capabilities through networked collaboration. NATO and its member nations state this vision in strategic documents at a very high level of abstraction. While suitable for giving an overall feel, current documentation renders the steps toward implementing those visions largely unsupported. We outline a method, based on agile requirements engineering, for converting high-level strategic visions into capabilities, whose form lend themselves to incremental implementation. We illustrate the use of this method in two cases that concern both operational capabilities and technical capabilities. We also  show how  the method enables one to prioritize  which capabilities to develop first. We conclude that some form of explicit methodology to span the gap between strategic visions and implementing those visions is necessary.
