“… Driskell et al (2023) provide a specific definition of a fluid team as comprised of four core characteristics; (1) team members are rapidly assembled to address an immediate problem, (2) members are assembled based on domain expertise and typically have no prior history or experience working together, (3) the team must begin work on a task that is immediate, time-critical, and of short duration, and (4) at completion of the task, the team disbands with little likelihood of further interaction. These types of teams, assembled temporarily from experts across various domains to accomplish critical, time-sensitive tasks, have become increasingly prevalent in various contexts such as the military, aviation, healthcare, and industry ( Bell et al, 2023 , this issue; Grossman et al, 2024 , this issue; Linhardt and Salas, 2023 , this issue; Capiola et al, 2020 ). Although fluid teams are typically convened to address complex and demanding tasks, little is known regarding how these teams should be assembled to support effective performance in this unique context.…”
