Case
A crime room for DITSS
Subversive crime leaves traces, but rarely in one place. An environment in which scattered signals come together, so that analysts can interpret what they see more quickly.
Sector
Investigation and supervision run on data that sits scattered across systems that were never designed for one another. For the Dutch police and DITSS we worked on exactly that question; at the Ministry of Defence and the Royal Netherlands Marechaussee it concerned the deployment of individual specialists.

The situation
In this domain there is rarely a shortage of data. It sits scattered across registrations, reports, systems belonging to chain partners and files that were each set up for a purpose of their own. So the question is almost never which new source to add, but what becomes visible when existing sources are placed side by side.
That is precisely the analysis we carried out for the Dutch police: which combinations of existing datasets yield new, relevant information, and which mainly yield spurious connections. That second half is the hardest and, here, the most important, because a connection that lights up by chance costs investigative time that nobody has to spare.
A wrong figure in a sales report costs a wrong decision. A wrong connection in an investigative environment affects people. Explainability is therefore not a quality requirement afterwards but a design requirement beforehand: for every outcome it must be possible to reconstruct which sources contributed to it and which processing was applied.
We believe technology should be reliable, transparent and explainable, certainly where decisions affect people. In this sector that is not a principle we add, but a requirement the organisation already sets itself.
Roles
Twentynext fulfils four roles: advising, supplying people, running projects and managing what is live. In this domain these three occur most often.
Specialists in your own team
Data engineers, BI specialists and data scientists who work inside your environment and your way of working. At the Ministry of Defence and the Royal Netherlands Marechaussee it took this form: the deployment of individual specialists.
Linking and analysing sources
Research into what scattered registrations show when taken together, with an equally clear judgement on where linking mainly produces noise. An honest no to a link is worth as much here as a yes.
From experiment to a managed facility
A working model is not the same as a working facility. We build on until it runs, is monitored and can be handed over: you can take it into your own management or leave it with us. If you choose the latter, we remain responsible: we have been managing some systems for more than five years.
Evidence
Case
Subversive crime leaves traces, but rarely in one place. An environment in which scattered signals come together, so that analysts can interpret what they see more quickly.
Case
Not which new data should be added, but what becomes visible when existing sources are linked to one another, and where linking mainly produces spurious connections.
Service
When you are not buying a project but capacity: specialists who work inside your own team, with our projects and R&D behind them.
Scope
The Dutch police and DITSS were clients; about that work we publish only what they permit us to. At the Ministry of Defence and the Royal Netherlands Marechaussee it concerned the deployment of individual specialists. About the nature of that work we make no statements.
We are not a defence supplier and do not present ourselves as one. What we bring is data and AI work: opening up and linking sources, building models that stay explainable, and keeping the facility running afterwards. If you are working on an assignment in this domain and lack those specialisms, that is the conversation we are glad to have.
Would you like to know where your organisation stands? Get in touch: we respond within one working day.

The people who build it also run it afterwards. Eindhoven, since 2014.
