2777 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.

  11. Stakeholder Analysis intermediate

    An architect faces conflicting requirements: sales wants a feature in six weeks, security requires a control that takes twelve, and the platform team wants it built on the paved road that does not yet support it. How should this be handled?
