Enterprise Architecture Consulting in Oberhausen, the Ruhr area & NRW
Your enterprise architecture consultant, rooted in the Rhine-Ruhr — from baseline analysis to a target architecture that holds and the governance around it, delivered by senior architects at home in the region.
Understanding This Service
Headquartered in Oberhausen / Ruhr area
Our office is at Inselstraße 27, 46149 Oberhausen — in the heart of the western Ruhr area, between Duisburg, Essen and Mülheim an der Ruhr. From there most sites across the Rhine-Ruhr region are reachable in under an hour.
Built for the Rhine-Ruhr region
Industrial mid-market, energy and utilities, logistics, insurers and a dense landscape of public-sector organisations: these profiles shape our project work — with the NRW context from our own practice.
Senior delivery, locally rooted
Local proximity replaces no seniority: on site, the TOGAF®-certified senior architect delivers personally — no locally staffed junior team, in German or English.
Why Clients Request This Service
Grown-up IT landscape after acquisitions or mergers
ERP or core-system replacement without an architectural foundation
Architecture knowledge without succession in the team
Cloud migration without a clear target architecture
Scope of Testing
Our local EA consulting in the Rhine-Ruhr typically encompasses:
Enterprise Architecture Assessment
Current landscape, gaps and quick wins made transparent within weeks — workshops in your premises across the Ruhr area or Rhineland, documentation remote.
Target Architecture & Roadmap
Target state across the business, application, data and technology layers, TOGAF®-based — sequenced, prioritised and executable by your team.
EA Governance & Enablement
Operating model, architecture standards and enablement — so the EA function stays in your organisation after the project: in Oberhausen, the Ruhr area, NRW.
How We Run This Engagement
1. First call
No-obligation first conversation with a senior architect — by phone, by video or on site with you in the Rhine-Ruhr region.
2. Assessment
Make the current architecture, risks and business alignment transparent. Workshops take place at your premises — not only in video calls.
3. Target architecture & roadmap
Design the target state across all four layers and sequence the implementation with measurable milestones — robust, not just slides.
4. Accompaniment & governance
Accompany the implementation and anchor the EA function in your team. Regionally, this works in short, frequent sessions instead of rare mega-workshops.
What You Walk Away With
Architecture findings report
Executive summary and technical findings with clear priorities, board-ready and readable for your stakeholders.
Target architecture model
Documented target enterprise architecture across all four layers, modelled in ArchiMate® and versioned.
Transformation roadmap
Sequenced, prioritised implementation plan with quick wins, dependencies and measurable milestones.
EA governance model
Operating model, architecture standards and roles for a lasting EA function inside your organisation.

What Makes Our Testing Different
Portamus is your independent enterprise architecture consultant in Oberhausen (NRW, the Ruhr area). We align the business and IT strategy of enterprises, public sector organisations and mid-market companies in the Rhine-Ruhr — on site at Inselstraße 27, 46149 Oberhausen or remotely across Germany, Austria and Switzerland.
Location and region: Oberhausen in the western Ruhr area
The head office is at Inselstraße 27 in the western Ruhr area, directly between Duisburg, Essen and Mülheim an der Ruhr. From there most sites across the Rhine-Ruhr region are reachable in under an hour — Duisburg, Essen, Mülheim, Bochum, Dortmund and Gelsenkirchen as well as Wuppertal and the Rhine metropolis of Cologne. Workshops and assessment sessions therefore take place at your premises, while documentation, modelling and design work happen remotely.
The regional rooting is part of the method, not marketing: architecture decisions in North Rhine-Westphalian organisations run into works council involvement, public-sector procurement rules, GDPR and BSI IT-Grundschutz. We know that context from our own practice — and we deliver in German or English, whichever your organisation requires. The German-language in-depth for the region — scope, industries and working style across North Rhine-Westphalia — lives at portamus.de: EA-Beratung in NRW und im Ruhrgebiet.
Services for the Rhine-Ruhr region
The usual starting point is an enterprise architecture assessment: current landscape, gaps and quick wins made transparent within a few weeks. That is followed by the target architecture and the roadmap from our enterprise architecture consulting; and where you want a lasting function, the build-out of your EA programme. Mid-market organisations in the region often start with the streamlined mid-market variant (in German on portamus.de: EA-Beratung für den Mittelstand) — after the free first call, the baseline analysis is with you on site within two to four weeks.
