This article draws on the institutional collective action (ICA) framework and data from a survey of senior public health and emergency management professionals in the Dallas–Fort Worth metroplex following the Ebola outbreak to investigate coordination effectiveness during public health emergencies. Based on the study findings, the article recommends that having an identifiable lead agency, official statements from local authorities, a conducive environment for informal conversations, and communication activities that inform, connect, and involve professionals is essential for an effective coordination. Practical implications of the study extend to how to mitigate collective action dilemmas with regard to coordinating COVID-19 pandemic responses.
