Development and validation of a model for assessing the success of employee portals

Many companies utilize employee portals to improve information exchange and communication between their employees as well as to better support business processes. Owing to limited IT budgets and the need to justify portal investments, assessing employee portal benefits is important. In this article, we propose a model for measuring employee portal success on the basis of the DeLone and McLean IS Success Model as well as an extensive review of employee portal success measurement literature. The resulting model is put forward as the foundation for future empirical work in this area. A card-sorting and item-ranking approach as well as a survey trial is conducted in order to validate the survey instrument. Methods of classical test theory are proposed for the further validation of the survey instrument and the assessment of the measurement model.
