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.

  6. Value Streams intermediate

    A quick-commerce business running dark stores maps the value stream for "launch a new product category".

On the strength of it, leadership funds a £600k pipeline programme to cut the 11 days. Review the map and the decision.
