Public Administration & Government

The OZG requires administrations to digitise hundreds of administrative services across federal, state, and municipal levels. Enterprise architecture provides the structured framework for planning and governing this delivery — mapping current processes, designing target digital service architectures, defining integration requirements, and producing the documentation needed for transparent programme governance and audit. Without an EA foundation, OZG projects frequently stall on integration complexity and scope ambiguity.

Yes. We design transformation programmes and architecture specifications that can be used as the technical basis for public procurement procedures — ensuring that requirements are documented in a way that supports compliant tender processes. We also support administrations in evaluating proposals and governing delivery by vendors selected through public procurement.

We begin with an architecture assessment of the systems and processes on both sides of the planned integration, then design the interoperability layer — defining data standards, API contracts, and governance models — before producing the specifications required for implementation. For cross-Länder or federal-state integration, we factor in the relevant technical standards such as XÖV data formats and the Portalverbund infrastructure.

BPMN (Business Process Model and Notation) is the standard notation for documenting administrative processes in a clear, unambiguous format that both business stakeholders and technical teams can work with. In public administration, BPMN process models form the basis for digital service design, process automation decisions, and the FIM Leika/FIM Prozesse artefacts required for OZG-compliant service delivery.

A focused EA assessment for a ministry department or municipal IT organisation typically takes six to eight weeks, covering stakeholder interviews, current-state landscape documentation, and a prioritised set of architecture recommendations. For larger federal or state-level programmes spanning multiple agencies and legacy systems, we recommend a phased approach starting with a scoped discovery to define the full assessment scope before committing to a timeline.

Integration architecture for public authorities defines how specialist procedures, registers, and portal-network infrastructure connect — through standardised interfaces (XÖV data formats, FIT-Connect) rather than fragile point-to-point couplings. Combined with disciplined architecture management and requirements management for e-government projects, it produces the tender-ready solution architecture that OZG delivery depends on.
