Seventy-three per cent complete. Six weeks behind, within tolerance. One amber risk. That is what most product development reporting looks like — and it can be entirely accurate while telling you nothing about whether the investment is working.

Answerable to Reality argues that product development is not production. A direction like \"grow,\" \"simplify,\" or \"improve\" has to become an explicit, quantified requirement before a team can be judged against it, a design compared to an alternative, or money called well spent or wasted. Drawing on Tom Gilb's engineering tradition — Planguage, Design-to-Requirements, Evo — the book works through a real multi-country product decision from the first vague slide to twelve months of evidence, including the parts that didn't confirm the theory.

It offers no maturity model, no certification, nothing to roll out on Monday — just a different lens to hold up against one real decision, for an afternoon, and see if the view is clearer.
