Often many features are integrated in a monolithic interface that should fit all needs. A new trend towards portal systems can provide flexible and user-adaptable environments. This paper therefore presents a new approach for the modularization of collaborative systems. We present the requirements analysis, the concept and implementation as well as experiences from a pilot of portal modules that were added to an existing Groupware system.enportal moduleindividualizationcustomizationgroupwaremodularization004005006conference paper
