When disaster strikes, the emerging task environment requires relief agencies to transform from autonomous mono-disciplinary organizations into interdependent multidisciplinary decision-making units. Evaluation studies reveal that adaptation of information management to the changing task environment is difficult resulting in poor information quality, indicating information was incorrect, outdated or even unavailable to relief workers. In this paper, we adopt a theory-driven approach to develop a set of information management roles and dynamic capabilities for disaster management. Building on the principles of advance structuring and dynamic adjustment, we develop a set of roles and capabilities, which we illustrate and extend using two field studies in the Netherlands. By studying regional relief workers in action, we found that in tactical disaster response decisionmaking units, several information management roles are not addressed and that information managers are preoccupied with information gathering and reporting, whereas information quality assurance is not on the agenda.
