Trend AI is entering organizational decision-making ahead of the discipline to govern it

Summary

Deloitte's third 2026 trend holds that AI is reshaping organisational decisions whether or not companies are ready. Leaders already face a torrent of fast, noisy and risky choices, and many turn to AI, with 60 percent of executives using it regularly to support decisions. Yet AI brings new challenges, from unclear accountability and weaker human ownership to agents acting at speeds that strain traditional controls. Deloitte's research shows that most organisations operate at low decision-making maturity. It recommends first strengthening decision-making as a distinct discipline and then deliberately designing how humans and AI share the role of decider. Done well, Deloitte argues, AI can strengthen human decision-making rather than override it.
