  3. EA Frameworks beginner Multiple choice

    Fourteen teams produce architecture diagrams nobody can compare. The same rectangle means a single service in one diagram and an entire platform in another; arrows sometimes mean data flow and sometimes deployment. Leadership cannot answer which applications support the claims capability or which run on the estate leaving support next year. The CIO asks which EA framework to adopt. Which move addresses the actual problem?

  4. Technology Architecture beginner

    An internal team and a packaged-software vendor both pick the same message serialisation format this quarter. Two years later the internal team replaces it in a single sprint. The vendor still supports it and expects to for another decade - an ERP vendor in SAP's position has customers whose 12-year-old integrations must keep working across a major release. Nothing about the technology differs. What makes the same choice a different decision for each of them?

  5. TOGAF beginner

    A team is told to build against a target architecture that was approved 20 months ago, in what the EA function called Phase C. Nobody has revised the document since, and two of its nine named products have been discontinued by their vendors. The Open Group's ADM runs a Preliminary phase and Phases A to H with Requirements Management at the centre. Which phase do organisations actually skip, and what does skipping it cost?
