The DSSC Maturity Self-Assessment turns “where we think we are” into evidence. Your own six-dimension reading of your initiative, taken on a scale you didn’t set. Re-run every cycle to show how far you've come.
The questions and maturity phases are taken from CEN/CLC/TS 18331:2026, Maturity assessment of Common European Data Spaces.
Illustrative replay. In a real assessment, each point is the score from your own answers across 52 questions, and the dashed shape is where you stood at your previous run.
No setup, no spreadsheet. Create an account, run the assessment, and walk away with a reading you can put in front of anyone.
One account for the whole platform. Use it to start a run and pick up where you left off.
Answer 52 closed-ended questions across six dimensions. Your answers save as you go.
See your radar, per-dimension scores and lifecycle phase, then export a PDF and take it offline.
Most initiatives can describe what they've built. Far fewer can show, on a common scale, where they stand, how they compare, and what to tackle next.
“Are we further along than last year, or does it just feel that way?”
Without a fixed yardstick, progress is a story. Stakeholders fund outcomes, not narratives, and gut feel doesn't survive a board review.
“Where do we sit next to comparable initiatives?”
You can't benchmark against peers without a shared definition of maturity. Everyone grades themselves on a different curve.
“How do I prove the year's work to the people funding it?”
A self-made scorecard is easy to wave away. A reading on a yardstick you didn’t set, the one your funders already recognise, is not.
Answer 52 closed-ended questions across six dimensions. Out comes a maturity radar, a percentage score per dimension, and the phase each dimension has reached, from Exploratory to Scaling.
Anyone can build a maturity checklist. Four things make this the reading that actually carries weight.
You measure against the European model from CEN/CENELEC’s formal standardisation process. The DSSC, EU-funded and vendor-independent, operationalises it as a free self-assessment: you answer, on a scale neither you nor we wrote. A yardstick no single party owns is what makes your own reading defensible.
CEN/CENELEC JTC 25 published the model as a Technical Specification under the Commission's standardisation request (Mandate 614). It's the yardstick your peers are measured against.
The model has already been run across Common European Data Spaces in the first consolidated maturity assessment ever conducted, surfacing real benchmarks, not a theoretical framework on paper.
Re-run it at your own innovation cadence. Each pass plots cleanly against the last, giving you a defensible record of progress to hand upward, every cycle.
Alongside the percentage scores, the model places each dimension on a five-stage path of its own. Each transition has clear, qualitative criteria, so "what do we do next" stops being a guess.
Objectives and value proposition explored; first use cases identified; governance under discussion.
Business model drafted and partly validated; rulebook drafted; data model and protocols defined.
At least one use case operational; governance and compliance live; trust and policy enforcement working.
Value proposition validated; contracts in place; participation and transactions actively monitored.
Cross-data-space interoperability; growth in participation and transactions; targets met or exceeded.
Run the assessment at the start of a cycle and again at the end. The two readings sit on the same axes, so a jump from one phase to the next becomes a single chart on fixed axes, the kind of result that closes out a stakeholder review instead of opening a debate.
A standardised model, the same scale, every time. That’s what makes the trend trustworthy.
Exploratory → Operational, one dimension, plotted on a fixed scale.
Walk into the review with a clear before/after, measured on a scale you didn’t set. Less time defending the work, more time getting the next round signed off.
The radar makes weak spots impossible to miss. Fix the gaps that hold back your phase transition, before they cost you momentum.
See where you sit across the landscape and within your domain, on the same scale everyone else is measured by. Comparable by construction.
It takes one sitting, costs you nothing, and gives you a reading you can put in front of anyone, on the scale Europe standardised on.
