This white paper tries to summarise the first initial thinking on capability development and capability platforms. This is the first attempt to sketch the main elements of a capability approach that will be developed in IO 01 activities over the next years. A capability approach to integrated operations can help us improve our understanding of how people, process, technology and governance issues are connected and managed to create scalable and sustainable practices. By coupling the notion of ecologies and platforms, we allow for an emerging model of integrated operations that recognizes the critical need of collaboration across traditional boundaries. In practice the technology solutions form the base of the platform with the more people, process and organisational dominant elements making up the top layers of the platform stack. We describe the content of such a capability platform in relation to integrated operations and present how it can be developed to create sustainable and scalable practices.
