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.

  10. TOGAF Exam Preparation and Certification

    Prepare for the two TOGAF papers with adaptive practice, then sit timed mock exams in the official format and earn the course certificate.

Who this is for
  • Complete beginnersYou start with no prior knowledge and learn the vocabulary of enterprise architecture before any method, in plain language throughout.
  • Students and career changersYou build a structured foundation from scratch across nine stages, then progress into the deeper TOGAF material the later stages cover.
  • Practising architectsYou gain deeper command of how business, data, application, technology and migration decisions connect and stay traceable through the full ADM.
  • Delivery and technical leadsYou see how delivery, migration and technology choices trace back to business drivers and pass architecture governance without losing pace.
  • Transformation managersYou get the method without jargon or theatre, so you can sponsor, fund and govern architecture work with real understanding.
  • Framework comparersYou learn where TOGAF helps, where it needs ArchiMate or BIZBOK support, and where it is the wrong fit entirely.
What you'll be able to do
  • Explain what EA is forYou set out what enterprise architecture delivers and tell the TOGAF standard apart from its guidance, certifications and common myths.
  • Run the full ADMYou work every phase from Architecture Vision through delivery, governance and change management, with Requirements Management at the centre throughout.
  • Build the core artefactsYou produce and critique principles, stakeholder concerns, capability maps, value streams, gap analyses, transition states and roadmaps in the repository.
  • Model with ArchiMateYou read and build ArchiMate models that turn TOGAF's business, data, application and technology domains into a shared, formal notation.
  • Compare the frameworksYou weigh TOGAF against BIZBOK, DoDAF, FEAF and Zachman on the same axes, and judge where each one genuinely fits.
  • Tailor and partition the methodYou adapt the method to scale, pace and regulation, and partition architectures by breadth, depth and time to stay workable.
  • Apply the London Grid caseYou apply every stage to London Grid Distribution, a fictional GB network operator built from DESNZ, Ofgem, NESO, NCSC and LTDS sources.
  • Prepare for both examsYou practise against both banks aligned to TOGAF Foundation and Practitioner: 164 single-answer questions and 32 scenario questions.
