Delivering added value public e-services often requires cooperation between two or more governmentdepartments. In general, such cooperation is ensured by implementing interoperability betweenautomated business processes. Although the existence of several works interested in public onlineservices in general, only few of them were focused on measuring interoperability degree, whether usedor required, to deliver them. In this context, the objective of this paper is to propose a new qualityindicator for interoperability assessment of public integrated e-services. This indicator takes intoaccount three main aspects: interoperation potentiality, interoperation compatibility and operationalperformance. Finally, to better illustrate how to use the proposed measurement method, we present apractical example of integrated public e-service. This work takes the case of a national library whichproposes an online registration service.
