An AI business case often looks precise: hours saved, FTE equivalent, annual benefit, payback period and ROI.
The arithmetic may be correct. The savings may still never appear.
PowerPoint savings are benefits that exist in a model but have no credible operating path into the P&L, revenue line or risk position.
Five common warning signs
FTE math onlyMinutes saved are multiplied by salary cost with no staffing or workload action.
No benefit ownerTechnology owns delivery but nobody owns realization.
Gross benefitsRun costs, support, governance and exception costs are omitted.
No timingThe model assumes benefits begin immediately at go-live.
No stage gatesThe next investment is approved before earlier benefits are evidenced.
44%
Gartner says only 44% of organizations had adopted financial guardrails or AI FinOps practices.
45%
of finance AI investments in Gartner's 2026 survey leaned toward productivity.
P&L
BCG recommends rigorous tracking so efficiency gains translate into actual financial results.
Realized, targeted and modeled are different words
A transformation case should distinguish benefits already realized from benefits targeted by an approved business case and benefits that are only modeled assumptions. Mixing them makes the economics look stronger than the evidence.
