Extreme environments such as disasters are often managed by several teams working towards a shared goal but with unique sub‐goals at individual and team levels. Whilst these multiteam systems provide potential access to a wide pool of knowledge and resources, public inquiries repeatedly highlight coordination difficulties, leading to conflicting decisions and actions. However, limited research has focused on examining the inter‐team processes used to coordinate decisions in situ within extreme environments in order to cross‐validate theory. Accordingly, the following study analyses naturalistic observations conducted during two large‐scale live disaster response exercises in order to examine (1) what inter‐team processes are used to coordinate decisions, and (2) the extent to which they correspond with a linear phase‐based ‘Joint Decision Model’ (JDM) introduced to national UK disaster response guidance. Findings show responders frequently either revert to gathering information rather than progressing to take action, or take action without deliberately considering options, powers, and policies to form a plan. These non‐linear decision processes remain largely similar across both exercises, indicating that the initial implementation of national JDM guidance has not yet led to substantial changes. Further focus is needed to identify mechanisms for improving coordination in practice, including the form and frequency of training required to maintain such complex skills.

在极端环境下运行的多机构多团队系统中的决策制定

诸如灾难之类的极端环境通常由几个团队共同管理，以实现一个共同的目标，但在个人和团队级别具有独特的子目标。尽管这些多团队系统提供了访问广泛知识和资源的潜在途径，但公共查询反复强调协调困难，导致决策和行动相抵触。但是，有限的研究集中在研究用于协调原位决策的团队间流程在极端环境中以交叉验证理论。因此，以下研究分析了两次大规模现场灾难应对演习中进行的自然观察，以检查（1）哪些团队间流程用于协调决策，以及（2）它们在多大程度上与线性阶段相对应基于英国的“联合决策模型”（JDM）引入了英国国家灾难响应指南。调查结果表明，响应者经常要么选择收集信息，要么不采取行动，或者没有刻意考虑方案的选择，权力和政策而采取行动。这些非线性决策过程在两个练习中仍大体相似，表明国家JDM指南的最初实施尚未导致实质性的变化。
