The work is structured into seven activities with the responsibilities and interactions with other activities as shown in the figure below.

ESMO follows the classic engineering approach of analsysis, design, implementation followed by integration and testing where: Activity 2 includes the analysis, design and implementation of the standard HUB (without country specific support to eIDAS connectivity) and also provides a test plan for all deployed services; Activity 3, 4 & 5 carry out the local service customisations and integrations with the HUB and eIDAS, for the respective participating Member States (Greece, Norway and Spain); Activity 6 performs the testing of all deployed services by the participating HEIs; and finally Activity 7 is responsible for dissemination, maximisaing uptake, sustainability and the roadmap of ESMO results.
