Sara S.
Last position:
Senior Software Developer with a Focus on UI/UX at vGen GmbH
Development of an interactive prototype for the concept of an AI-supported Enterprise Architecture Management tool. The goal was to present complex relationships between IT systems, business processes, and departments in a way that is easy to understand and to support decision-making in the context of IT transformations.
The prototype combined data-driven analyses with guided questions and interactive visualizations. A central part was the integration of a RAG process to provide domain-specific EAM knowledge in context. The focus was on quick idea validation, user-centered interaction design, and the technical feasibility of a scalable overall concept.

About the technology
What it covers
Enterprise Architecture connects business goals, operating models, information, applications and technology into one practical view. It helps companies decide which capabilities to build, which systems to retain, and how change should be governed. The work turns complex landscapes into a clear direction for investment and delivery.
What it delivers
Experts create current-state assessments, target architectures, transition roadmaps and principles for future decisions. Typical deliverables include capability maps, application portfolios, data models, integration views, technology standards and architecture decision records. The focus is a usable blueprint, not documentation for its own sake.
Ecosystem and methods
Enterprise Architecture may draw on TOGAF, ArchiMate, business capability mapping and domain-driven design. Specialists also work with cloud landing zones, API management, event-driven integration, identity, data governance and portfolio tools such as LeanIX or Sparx Enterprise Architect. Their approach must fit the company’s delivery model and regulatory context.
When companies engage specialists
- Legacy estates block product or process change
- A cloud, ERP or platform transformation needs a coherent target state
- Mergers create duplicate applications, data and operating models
- Technology decisions lack shared principles and ownership
- Architecture governance slows delivery instead of supporting it
Freelance expertise adds independent structure when internal teams are busy, a transformation needs momentum, or a specialist perspective is missing. In Düsseldorf, collaboration may combine remote workshops with on-site sessions for business and technology stakeholders.
Skills that matter
Strong professionals connect executive priorities with delivery constraints. They understand business capability analysis, solution and system architecture, integration patterns, data management, security, governance, financial trade-offs and organisational change. They can explain complex dependencies to leadership while giving delivery teams decisions they can act on.
How quality shows
A capable specialist asks precise questions before proposing a target state. They make assumptions visible, compare options against business outcomes, and define measurable decision criteria without locking the company into a preferred vendor. Good work leaves clear ownership, realistic sequencing and architecture guardrails that teams can use in daily delivery.
Frequently asked questions
Key details about Enterprise Architecture, drawn from the questions we get asked most.
Enterprise Architecture is used to connect business strategy with capabilities, processes, information, applications and technology. It supports decisions about transformation roadmaps, platform investments, operating models, integration and governance.
Enterprise Architecture looks across the organisation and its strategic change agenda, while solution architecture focuses on a specific product, system or initiative. The two disciplines should align: enterprise direction sets constraints, and solution decisions test whether that direction works in practice.
A strong Enterprise Architecture specialist often combines capability mapping with cloud strategy, data architecture, security, integration, portfolio management and organisational change. Familiarity with TOGAF, ArchiMate, LeanIX or Sparx Enterprise Architect can help, but practical decision-making matters more than a tool list.
The right Enterprise Architecture experience depends on scope, governance complexity and the number of business areas involved. A focused application or cloud roadmap may need a specialist who can work hands-on with stakeholders, while a group-wide transformation calls for experience with executive decisions, dependencies and change sequencing.
Enterprise Architecture can be delivered remotely when workshops, repositories and decision forums are well organised. On-site sessions in Düsseldorf can still add value during discovery, stakeholder alignment and sensitive governance discussions, especially when teams span business and technology functions.
A typical Enterprise Architecture engagement may produce a current-state assessment, capability map, target architecture, transition roadmap, principles and decision records. The exact set should follow the decisions the company needs to make, rather than creating documents without clear owners or use.
Look for an Enterprise Architecture professional who links recommendations to business outcomes, states assumptions and explains trade-offs clearly. Ask for examples of roadmaps that influenced delivery, governance that enabled faster decisions, and architecture work adopted by teams rather than left in a repository.
Companies may compare Enterprise Architecture with a narrower technology strategy, portfolio review or transformation office approach. Those options can address selected decisions, but Enterprise Architecture is valuable when business capabilities, processes, data, applications and technology must be considered together.
