2627 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.

  1. Business KPIs intermediate

    A marketplace launches in a new city. Supply and demand are both near zero. What architectural support does this need?

  2. Business KPIs intermediate

    A streaming platform's engineering team optimises for latency and availability while the business measures watch time and creator retention. How should these connect?

  3. Business KPIs intermediate Multiple choice

  4. Business Processes intermediate Multiple choice

    A food-delivery platform handles 220,000 orders a day. About 1.8% of orders raise a refund dispute. Automated rules settle most of them but 22% reach a human agent who spends roughly 9 minutes per case. A fully loaded agent costs about £38,000 a year and delivers about 1,500 productive hours. Roughly what does the manual tail cost per year?

  5. Business Processes intermediate

    A manual onboarding process handles about 400 cases a month. Automation covers the standard path, and after six months roughly 20% of cases still go to a person because each has some exception. The team proposes automating the remaining exceptions. How should this be sequenced?

  6. Business Processes intermediate

    A process takes eleven days end to end and involves four hours of actual work. What does that tell you and where do you look?

  7. Capability Mapping intermediate

    A services marketplace maps its architecture by listing its microservices. Why is that not a capability map, and what does the difference change?

  8. Capability Mapping intermediate

    An enterprise builds a capability map and it is never used again. What makes capability mapping produce decisions rather than documentation?

  9. Capability Mapping intermediate

    You have mapped capabilities and overlaid cost and differentiation. What decision does that enable?

  10. Organisational Constraints intermediate

    Every change to a cross-team interface must be approved by an architecture forum that meets weekly with six 20-minute slots. About 14 requests arrive each week. Over the next two quarters, what happens to the queue and — more importantly — what happens to the designs themselves?

  11. Outcome Measurement intermediate

    A nine-month consolidation retired four systems and released about 0.4 FTE of support effort in each of four teams. The programme closed as a success, verified by the delivery plan. Eleven months after the business case was signed, finance reports run cost unchanged and the £1.2m annual saving nowhere in the ledger. What failed, and which decision made it possible?

  12. Outcome Measurement intermediate

    A platform ships a major architectural change and declares it successful because it was delivered on time. What should have been measured?
