The development of Interoperability is a necessity for organisations to achieve business goals and capture new market opportunities. Indeed, interoperability allows enterprises to exchange information and use it to seize their shared goals. Therefore, it should be verified and continuously improved. This is the main objective of the Interoperability Assessment (INAS). Indeed, such an assessment aims at determining the strengths and weakness of an enterprise in terms of interoperability. Many surveys and reviews have been proposed in the literature to analyse the existing INAS approaches. However, the majority of these reviews are focusing on specific properties rather than a general view of an INAS. Therefore, this paper proposes a systematic literature review of INAS approaches. The objectives are to identify the relevant INAS approaches and to compare them based on a holistic view based on their similar and different properties (e.g. type of assessment, the used measurement mechanism, and the addressed interoperability barriers). A bibliometric analysis of the selected INAS approaches is also conducted with a discussion of their advantages and limitations.
