This paper investigates the relevance and assurance of information and system quality as requirements for information systems success during disaster management. Despite the many examples of poor information quality and poor system quality, research on the relevance and assurance of these requirements is sparse. In order to design successful information systems for disaster management, a context related understanding of the organizational and technical measures for achieving these requirements is necessary. Accordingly, the goal of this paper is to identify and confirm information and system quality requirements for the design of information systems for disaster management. The results of our interviews with information architects indicate that while information quality requirements are considered to be very relevant, these are hard to measure and assure, and that currently much effort is being put into improving system quality requirements such as interoperability and ease of use.
