Abstract: Information is an essential part of disaster management. Information systems (IS) are a key means of providing the right information at the right time to support response to a disaster, and fostering collaborative facilitators such as situation awareness, common ground and communities of practice. However for these collaborative facilitators to support 'downstream events' (i.e. disaster response) they need to emerge and be grown from 'upstream' activities such as user engagement. Subsequently IS design requirements for disaster response are embedded in the community where a system will be used and it is from the community users and their needs that IS requirements must emerge. This paper presents an upstream-downstream approach for disaster management IS design. We describe four phases to user centered information systems design to support disaster management and provide a case study of using this approach in action to design an IS to enhance community resilience. © 2012 ISCRAM.
