Once-Only Technical System Projectathon #1 Insights

From 19-21 April 2023, the first Once-Only Technical System (OOTS) Projectathon brought together 25 EU Member States in Brussels in a marathon of peer-to-peer interoperability testing. A Projectathon is a crucial step in the development, testing and deployment into production of the Once-Only Technical System components that underpin a national Once-Only implementation.

Once-Only will help to ease administrative burden on companies, with resource savings even greater for smaller companies with more limited resources.

It will also have great benefits for European citizens. The Once-Only Technical System means that when completing an online procedure, citizens will be able to give their explicit request to retrieve evidence from a competent authority in another Member State. This explicit request triggers the retrieval of evidence from competent authorities across many different sectors through the Once-Only Technical System (education, vehicles, population registers and more).

This Projectathon provided EU countries with an excellent opportunity to verify that their national Once-Only systems or solutions effectively comply with the appropriate specifications, laid out in the Once-Only Technical System Implementing Regulation and Technical Design Documents.

Neutral experts, acting as Monitors, supervised and verified the tests over the three days. The Once-Only Technical System Projectathons are not pass/fail type examinations. Rather, they are a collaborative exercise in understanding technical and operational issues and working together to solve them.

Ahead of the December 2023 legal deadline to implement the Once-Only Technical System, the European Commission is organising two more Projectathons, allowing the participating teams to build on their experiences.

Other Past Projectathons

Since 2023, the Commission has been organising Once-Only Technical System Projectathons. These are three-day events where national teams connect various systems and perform a marathon of peer-to-peer interoperability and compliance tests in a structured environment.

Projectathon #3

The October Projectathon is the final such event in 2023, just ahead of the legal deadline for EU Member States to implement the Once-Only Technical System. It builds on the work and experiences of the April and June Projectathons.

Projectathon #2

The June Projectathon provided a valuable moment for national implementation teams to perform interoperability tests prior to the summer recess.
