Common Information Systems Maturity Validation Resilience Readiness Levels (ResRLs)

This revised study expands a series of investigations of the resilience readiness levels (ResRLs) of information systems, including their aspects, factors, definitions, criteria, references, and questionnaires. The aim is to contribute to the combined total maturity measures approach and the pre-operational validation of shared and adaptive information services and systems. The overall research question is followed: How can ResRLs be understood in the domain of shared operative information systems and services? The purpose of the study to improve the manner of information systems acceptance, operational validation, pre-order validation, risk assessment, the development of adaptive mechanisms, and the integration of information systems and services by actors and authorities across national borders. The main contribution of the study is in the validation of the maturity of operative information systems regarding their resilience, including the examination of several factors and descriptions of technical resilience. In addition to the validation of maturity, the study expands the revised compatibility of maturity levels by upgrading the ResRLs seven-layer model to the nine-level model according to technological readiness levels (TRLs) and integration readiness levels (IRLs) to improve the responsiveness of the European Operational Concept Validation framework.
