Deloitte says enterprise AI agent pilots fail to reach production 89% of the time

Deloitte’s 2026 Tech Trends research says enterprise AI agents are struggling to move beyond pilot programs, with an 89% failure rate from pilot to production. A separate Teradata survey found that 78% of companies have run at least one AI agent pilot, yet only 14% have expanded those deployments across the organization. The research points to six main barriers: scope creep, data access problems, missing evaluation frameworks, unclear ownership, uncontrolled costs, and security approval issues. Other 2026 studies cited in the report show the same pattern. Gartner’s April 2026 survey of 782 infrastructure and operations leaders found that about 120 out of every 1,000 funded AI projects made it into production, and only 34 achieved return-on-investment targets. McKinsey said just 11% of companies had truly scaled AI agent use. Forrester reported rollback rates of 47% for production AI agents without automated evaluation, compared with 9% for agents covered by full evaluation systems. An industry survey also found that 83% of enterprises need infrastructure upgrades to support agentic AI deployments.
