Heterogeneous IT and business-application landscapes
Many systems have grown historically, are only loosely integrated, and hinder end-to-end digital processes.
Industry
IT consulting for sovereign, modern, and resilient public-sector digitalization.
We help government agencies, municipal IT service providers, and system owners modernize complex IT landscapes, design secure digital services, and reliably deliver transformation programs.
From target picture and architecture through business applications, interfaces, and data flows to implementation, we support digitalization initiatives that make public administration more effective.

Challenges
The public sector faces the challenge of delivering digital services faster, more securely, and more user-friendly. At the same time, statutory requirements, federal structures, limited resources, and legacy IT landscapes converge.
Many systems have grown historically, are only loosely integrated, and hinder end-to-end digital processes.
GDPR, IT security, federal standards, and sovereignty requirements must be translated into robust architectures.
Digitalization initiatives must not only be designed but implemented in a user-centric, stable way that delivers value in daily administrative operations.
Our contribution
We combine public-sector expertise with technical architecture, platform capability, and delivery experience — turning digitalization goals into reliable implementation.
We structure digital target pictures, roadmaps, and architecture decisions for achievable public-sector digitalization.
We support the modernization, integration, and evolution of business applications, data flows, and interfaces.
We build robust platform foundations for secure, scalable, and sustainably operable digital public services.
We support programs through to implementation — with clear governance, accountability, and change capability.
Focus areas
We support target pictures, data flows, interfaces, and implementation paths for modern register landscapes.
We support the modernization and integration of business applications with a focus on stability, usability, and operations.
We help think through administrative processes end to end and implement them in a digitally robust way.
We create clear integration models between business applications, platforms, data sources, and portals.
We make government data structurally usable — for governance, transparency, and better decisions.
We support secure, scalable, and governance-ready platform architectures.
We bring structure, roles, and prioritization to complex digitalization programs.
Stakeholders
Public-sector digitalization only succeeds when business requirements, technical standards, and operational feasibility come together. 1st supports different stakeholders with consulting, architecture, and delivery expertise.
For organizations that need to modernize digital services, business processes, and platforms and operate them long term.
For public-sector IT partners delivering secure, scalable, and integrable solutions across many business areas.
For teams translating business applications, interfaces, data flows, and user requirements into stable solutions.
Why 1st
1st combines technological depth with implementation-strong consulting. We work at the intersection of strategy, architecture, and delivery — exactly where public-sector digitalization initiatives need to become robust and sustainable.

"Public-sector digitalization becomes robust when business ownership, architecture, and delivery share responsibility together."
