## Summary

The article analyses why enterprise AI projects so often remain stuck at the pilot stage. According to McKinsey & Company's State of AI, nearly two-thirds of organisations have not yet begun to deploy AI at enterprise scale. According to IDC, 88% of AI proofs of concept never reach production. The author explains that the real obstacle is not technological capability but integration into business processes, change management and governance. He distinguishes between visible AI agents (assistants) and invisible agents embedded in workflows, and recommends right-sizing the technical architecture: for 80 to 90% of use cases, a small model is enough, rather than a frontier model.
