Enterprise Architecture

This course starts from absolute basics and teaches enterprise architecture through TOGAF 10 as a working method, not as a memorisation exercise. Each stage combines the core standard, the relevant Series Guides, practical judgement, and one recurring London Grid Distribution case so the method stays tied to real enterprise decisions.

The route is deliberately integrated. Business architecture is taught with business-model, capability, value-stream, and planning depth. Information systems architecture is taught with information mapping, authority, metadata, analytics, and building-block selection. Governance is taught as operating behaviour, not as a decorative appendix.

What you will learn

  • Explain what enterprise architecture is for, and distinguish TOGAF's standard content from guidance, certifications, and common mythology
  • Work through the ADM in a practical way that connects business architecture, information systems, technology, migration, and governance
  • Use TOGAF Series Guide ideas in context rather than as disconnected side reading
  • Build and critique repository artefacts including principles, stakeholder concerns, capability maps, gap analysis, transition states, and governance records
  • Compare TOGAF with ArchiMate, BIZBOK, DoDAF, FEAF, and Zachman using defensible comparison axes
  • Apply the London Grid Distribution case to turn TOGAF concepts into realistic architecture decisions, evidence packs, and roadmap thinking

Who this course is for

  • Non-technical professionals who need a plain-language route into enterprise architecture and TOGAF
  • Students, analysts, and early-career practitioners starting from scratch and needing a structured foundation
  • Architects, engineers, and delivery leaders who want a deeper practical understanding of how enterprise decisions fit together
  • Managers and transformation leads who need to understand architecture without turning it into jargon or theatre
  • People comparing enterprise architecture methods and wanting to understand where TOGAF helps, where it needs support, and where it is the wrong fit

Prerequisites: None. The course starts from absolute basics, explains the vocabulary in plain language, and then builds toward deeper TOGAF work.
