Technology availability has significantly encouraged information sharing in organizational coordination processes distributed over various (geographically) locations. However, the huge amount of available information, the heterogeneous nature of the information resources, and the information seekers dynamically changing information needs make it increasingly difficult for organizations and information seekers to find the right information in the right format and at the right time. The objective of our research was to formulate a new design theory aimed at improving current ways of designing personalized multidisciplinary information seeking and retrieval systems (PMISRS). Taking advantage of valuable theoretical models and frameworks developed in the fields of information retrieval, information seeking, context-aware computing, situation awareness and service-oriented approaches, we explored a set of concepts and relationships required for modeling and designing PMISRS. These concepts and relationship are independent of any domain semantics. They can be used to represent the characteristics of a wide range of information intensive domains at a high level of abstraction. We tested and evaluated the applicability and the novelty of our design theory by applying it in a case study in which we built a prototype of a PMISRS in a typical multidisciplinary information intensive domain, crisis response in a Port.
