# Deloitte

**Role in this source:** the cited source for the AI payback-timeline statistic.

Cited for a survey of **nearly 2,000 executives** finding that satisfactory ROI on a typical AI use case takes **two to four years**, far longer than the standard **7–12 month** tech payback period. This is the backbone of [[claim-ai-roi-timeline]].

**Canonical reference.** Deloitte's AI executive surveys are the likely canonical source family for the long-payback claim — though, per the enrichment overlay, the exact survey used in the article is not present in the search set, so the precise figure is unconfirmed from available evidence.
