Cash and capacity, kept apart
Most AI business cases turn every minute saved into money. Owners see through that. We count four kinds of cash that really move: external spend avoided, the cost of work waiting, revenue you currently miss, and avoidable errors or waste. Time saved is shown as capacity, and only counts as cash if you will genuinely buy fewer hours.
Every cost, including people
Licences and usage are the visible costs. Build, the knowledge library, training and ongoing support follow. Then the one most cases leave out: the hours people spend approving and checking the agent's work. A good agent keeps people in every decision that matters, and that time is real.
Ramp, risk and readiness
Benefits ramp up over three years rather than arriving on day one. A confidence haircut reduces benefits, and contingency increases costs, in the spirit of Forrester's Total Economic Impact method. Each readiness question you cannot yet answer adds a further 10% haircut, because an unclear process automated is still an unclear process.
