The process of debriefing is argued to be the most critical stage during the simulation exercises of high-risk maritime operations. Debriefing is an important step in simulation-based learning exercises for promoting structured discussions and identification of learning gaps. However, it is especially crucial when considering the teamwork component of the maritime operations. During the debriefing stage, the participants, i.e., the instructors and the maritime trainees, have the opportunity for group-level reflection and identification of corrective measures for sub-optimal activities in relation to the learning objectives. A variety of mediational tools and resources can be utilized by the instructors for highlighting the performance of the learners and providing feedback. In this chapter, we look into the process of establishing a conducive environment for facilitating the debriefing process, as well as the various debriefing models that can be utilized for orienting the reflections and feedback. The success of the debriefing stage, which occurs towards the end of the simulation exercises, depends to an extent on the productive debates related to the learning objectives and key takeaway messages for the participants. Therefore, the chapter focuses on how the participants can achieve the same, thereby meeting the intended goals of the simulation exercises.
