| Summary: | Submarine control rooms are characterised by dedicated individual roles for information types (e.g. Sonar operator processes sound energy), with individuals verbally reporting the information that they receive to other team members to help resolve uncertainty in the operational environment (low information integration). We compared this work design with one that ensured critical information was more readily available to all team members (high information integration). We used the Event Analysis of Systemic Teamwork (EAST) method to analyse task, information, and social networks for novice teams operating within a simulated submarine control room under low versus high information integration. Integration impacted team member centrality (importance relative to other operators) and the nature of information shared. Team members with greater centrality reported higher workload. Higher integration across consoles altered how team members interacted and their relative status, the information shared, and how workload was distributed. However, overall network structures remained intact. PRACTITIONER STATEMENT: Wider integration (distribution) of information within teams in a simulated submarine control room altered the content of the information shared between team members and the centrality and workload of team members. Practitioners must consider how to integrate information in sociotechnical systems such that information traditionally held by specialist positions can be distributed within teams to benefit team performance and other outcomes.
