About Structural Interoperability Quick Assessment Toolkit

The Structural Interoperability Quick Assessment Toolkit (SIQAT©) has been developed in the context of Action 2016.36 Assessment of trans-European systems supporting EU policies of the Interoperability solutions and common frameworks for European public administrations, businesses and citizens (ISA2 programme). 

The objective of the SIQAT© is to allows public service owners to evaluate the structural interoperability maturity level of their digital public service. The Structural Interoperability Quick Assessment Tool (SIQAT) which provides public administrations with insight into two key aspects of the structural interoperability of their digital public service:

  • Shareability: It is the extent that an open standard enables prospective coexistence of an off-the-shelf asset in a given domain set of digital public service value chains.
  • Reusability: It is the extent that an open standard enables the coexistence of an off-the-shelf asset in a given value chain of a digital public service.


The toolkit is fully compliant with all European Interoperability Framework (EIF) recommendations for the development and improvement of public services.

The SIQAT© comprises the following release components:

The expected benefits of the SIQAT© are listed as follows:

  • It spots areas for improving the interoperability in a given solution;
  • It supports portfolio management decisions:
    • by suggesting solutions that could be published in the European Interoperability Cartography (EIC);
    • by clustering solutions with regard to interoperability maturity;
    • by identifying solutions that should be improved in term of interoperability.
  • It is applicable to any software solution supporting public services (not only for TES);
  • It saves time and resources in interoperability peer-to-peer tests by acting as a gateway to it. If the result of the Interoperability quick assessment is below the suggested threshold then it is recommended not to invest further efforts in a full interoperability peer-to-peer test;
  • It supports end users of the EIC in verifying the overall interoperability score of any published solution.

Based on the automatically computed Interoperability Assessment Score, the toolkit provides a five stage interoperability maturity level model for each of the aforementioned two interoperability areas. It indicates the potential interoperability maturity of a specific solution by providing a reference rate (from 0% to 100%), with clear recommendation on how to improve each area.

Building on this maturity level of the specific digital public service, the Solution Owner can activate technical improvements aimed at increasing the potential interoperability of the digital public service.
