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.

  4. Technology Radar intermediate

    Thoughtworks has published its Technology Radar since 2010 and now twice a year - volume 33 appeared in November 2025 - sorting technologies into adopt, trial, assess and hold from blips submitted by client project teams and curated by an internal group. An enterprise copies the artefact: the same four rings, a page per technology, published quarterly by a central architecture team of five. Two years on, teams do not consult it before choosing tools. What did the copy leave out, and where would copying the original be a mistake?
