An Infrastructure as Code business case is rejected far more often than the technology deserves, because the paper counts build hours, omits the platform run cost and never shows where the saved capacity went. This guide gives you the working: a costed investment baseline including the lines most models drop, the four benefit streams that carry almost every case, how to price engineer hours and failed changes without double counting, the payback, NPV and sensitivity maths finance expects, a fully worked two-year model for a 240-server estate, the benchmarks worth quoting, and the specific errors reviewers use to reject a funding request.
