Which AI use cases deliver fastest ROI?

The provided sources do not identify specific AI use cases that deliver the fastest return on investment (ROI). While the documents note that sales professionals using AI see 47% higher productivity [3] and that early adopters of agentic AI are achieving measurable returns through labor productivity, accelerated decision-making, and process automation [8], they do not rank these or other use cases by the speed of their financial return. Instead, the sources emphasize that achieving ROI depends on strategic implementation, such as building connected workflows and governed data foundations [2], focusing on targeted use cases [4], and ensuring that AI initiatives are aligned with business outcomes rather than just adoption [9], [12].
