E-OCVM stands for the European Operational Concept Validation Methodology and is a framework that has been developed in 2004 by Eurocontrol in collaboration with several R&D partners including the ATM & Airports Department of NLR. Generally, the E-OCVM is based on the methodological approach described by the Master European Validation Plan (MAEVA) project in its Validation Guideline Handbook (VGH).The MAEVA VGH suggests a five-step approach to validation that was originally defined in the Eurocontrol Development of EATCHIP/EATMP Validation Methodologies (DEVAM) project. As refined and expanded, these five steps form the core of the VGH. In order to address each of the steps at the appropriate level and for the appropriate audience, the VGH contains three parts, each describing the steps at different levels of detail. Despite the general acceptance of the VGH within the ATM community, several adaptations of the framework were proposed within European R&D initiatives (especially the Gate-to-Gate and C‑ATM projects) concentrating on the initial approach to validation activities and the related life cycle of the concept or technology to be validated.
Eurocontrol together with the Co-operative Approach to Air Traffic Services (CAATS) project team (responsible for co-ordinating validation approaches within the current European Commission Framework Programme) consolidated all change proposals in the first edition of the E-OCVM, which has become the mandatory methodological framework for concept validation within the European ATM community.
The E-OCVM addresses validation at the highest two levels of the MAEVA stepped approach, and additionally introduces a concept life cycle model as well as a so-called case-based approach. The latter integrates validation exercise results into key cases that directly address stakeholder issues about ATM performance and behaviours.
