Network Rail: From Fragmented Technology to Connected Decisions

Network Rail is using SAP LeanIX as a central Enterprise Architecture platform and source of truth to improve visibility and control over its technology landscape. The platform helps bring together information about business capabilities, applications, interfaces, technology components, ownership, risks and dependencies into a connected view. Key areas of use include: Application Portfolio Management – understanding what applications exist, who owns them, what they support and how they are used. Application Rationalisation – identifying duplication, redundancy and opportunities to simplify the application landscape. Technology Risk & Obsolescence – highlighting ageing technologies and potential technology risks. Business–IT Alignment – linking applications and technology to business capabilities to understand business impact. Architecture & Roadmap Planning – supporting transformation planning, scenario analysis and future-state architecture. Decision Support – providing architects, technology teams and leadership with visual insights to make faster, fact-based decisions. In simple terms: > Network Rail is using SAP LeanIX to move from fragmented technology information to a connected, transparent and data-driven view of its enterprise architecture—helping teams understand the current landscape, identify risks and duplication, and make better decisions about the future. This aligns closely with Network Rail's publicly described objectives of improving application inventory and portfolio clarity, IT risk and obsolescence management, business–IT alignment, and speed to insight.
