Once-Only Technical System Projectathon #3 Insights
On 23 November 2023, the European Commission published the event report for the October 2023 Once-Only Technical System Projectathon, a third and final marathon of peer-to-peer testing helping implementation teams from EU Member States prepare their respective Once-Only Technical System implementations in 2023.
This October Projectathon welcomed 24 Member States, on-site or online and as active participants. Participants executed 478 peer-to-peer tests, compared to 59 tests in April 2023, and 149 in June. This event concluded with a success rate of 91% for tests between participating countries. Building on the work of April and June Projectathons, this event also contributed to building a community out of the teams implementing the Once-Only Technical System. One participant noted: “the value of these events go beyond the actual testing and its benefits. The possibility to exchange ideas and best practices, and discuss the challenges with colleagues from other Member States is important. Thank you for organising!”
On 11-12 December 2023, a Go-Live Accelerator will drive the transition from the testing phase of the project to the operational phase of the system. It will mark the point where the system is deemed established and the Common Services ready to be used by Member States.
