Assessing Interoperability Assessment

Efficient integrated systems depend on strong interoperability, which is a non-functional requirement for heterogeneous systems. Objective mea- surement is essential for assessing a system’s adherence to interoperability norms. This paper conducts a systematic literature review to identify meth- ods for objectively measuring interoperability. The review uncovers the presence of well-established, subjective methods. Consequently, the paper proposes integrating objective measurements into a standardized model to improve interoperability measurement across various sectors and systems. The proposed integration approach seeks to replace a collection of opinion- based questionnaires with a unified standardized method for objectively measuring interoperability.
