Assessment Methodology for a Maturity Model for Interorganizational Systems -- The Search for an Assessment Procedure

The benefits of interorganizational systems (IOS) can often not be realized due to unknown or undiscovered impediments, technical deficiencies or lacking organizational capabilities. Maturity models are prominent examples for the assessment of organizations and their capabilities for interoperability. Nevertheless, they are often subject to critiques with respect to their purpose of use, model evaluation, general structure and assessment methodology. This research paper analyses 43 existing maturity models in the domain of IOS with a special focus on the assessment methodology. The goal is to find existing assessment methodologies that can be adapted to a new maturity model for IOS. The findings indicate that there is no common or established assessment methodology present but several assessment types. We propose an assessment method matrix for classification and allocation of assessment methods and types according to Model Complexity and Subject Complexity to determine an assessment methodology.
