A large number of FOI's operational analysts are seconded in different parts of the Swedish Armed Forces Headquarters. During the last decade, these analysts have become increasingly involved in providing direct support during staff exercises. That activity is the main focus of this report. Nine operational analysts who have experience of these activities were interviewed in order to obtain an overview of how OA support has been conducted and which tasks have been performed. The interviews attempted to focus specifically on what methods have been used and if there are any particular tools that should be highlighted. A minor literature review has also been performed. The findings were sorted into four categories: (i) Knowledge Development, (ii) Planning, (iii) Operations Assessment and (iv) Support to Decision-Making, where Operations Assessment stood out as the most recurring topic. All of the interviewees had taken part in tasks related to this process, regardless of the exercise, or the level of staff. Among the tasks, those that involved the planning process were abundant, as were those that can be classified as part of general support. Activities related to knowledge development were supported less. One reason is that in exercises OA is usually not part of the preparation phase, which is where much knowledge development may occur. The conclusions of this study suggest that there is a strong correlation between the staff position an operational analyst has and the tasks performed during exercises. This implies that placement largely determines the tasks that can be supported. Also, better advantage should be taken of the experience of individual analysts; doing so generates collective knowledge and provides even more competent support. Such measures would certainly assist junior OA and raise their initial skill set. Finally, since operations assessment is so predominant among the tasks performed by OA, it needs special focus.
