The aim of this study is to suggest development, on the basis of Comprehensive Approach, for increased effect in civil-military cooperation at a strategic and operational level at the Swedish Armed Forces HQ. A model for identifying central variables and contexts that affect the capacity to cooperate is presented. One conclusion is that civil-military cooperation is carried out in an environment characterized by lack of governing policies, constant organizational change and frequent exchange of personnel, mainly at the HQ, but also at the MSB. Recommendations: Civil-military cooperation should be planned and governed. Cooperation should have an identified purpose that leads to increased effect in operations. Informal cooperation should be regarded as complimentary. A function for civil-military cooperation should be organized to be resilient to reorganizations at the HQ and exchanges in personnel. The Swedish Armed Forces should, together with MSB and other agencies, agree on methods on how to reach a common problem picture and on how to use NATOs planning system COPD. Representation in civil-military contexts should be given higher status and followed by specific requirements on individuals. Liaison officers should be appointed to overcome distance between the political and the strategic/operational level.
