{"product_id":"estimation","title":"19 - Estimation","description":"\u003cp\u003e\"It'll cost around 250,000.\" A round number, delivered with confidence, and already wrong. Most budgets overrun not through bad luck, but because a hope was mistaken for an estimate.\u003c\/p\u003e\u003cp\u003eEstimation replaces the magic number with an honest range: you break the work down, set three bounds per item, aggregate into a confidence interval, and refine as you go. You follow the method step by step — through to the final calculation that turns \"about 250\" into \"636, guaranteed between 575 and 697 at 95%\".\u003c\/p\u003e\u003cp\u003eThis guide does not teach you to predict the future.
