2667 questions of the kind that actually get asked — in interviews, in architecture review boards, and by the person who has to run the thing at 3 AM. Every answer states the trade-off rather than the slogan, and says when the obvious choice is the wrong one.

  9. Regulatory Constraints advanced

    A company operates one platform across many countries with different regulatory regimes, payment rails and tax rules. How should the architecture handle variation without forking per country?

  10. Regulatory Constraints advanced

    A financial-services group has 14 months before a new operational-resilience regime applies. It must hold a complete register of third-party arrangements supporting critical functions, documented and tested exit plans for each, and contractual clauses that roughly 40% of its 180 supplier contracts do not contain. The programme plans to build the register first because it is the visible deliverable. Sequence the work properly and name the point of no return.
