​Is A Chief AI Officer The Answer To AI Accountability?

Mark Thirlwell, Global Digital Director at BSI.

“The buck stops here.” When Harry Truman popularized the phrase, he was speaking about presidential power and responsibility. Roughly 80 years on, we’re starting to see this idea of personal accountability applied to AI, with governance moving from sitting within information and communications technology (ICT) or strategy functions to being a board‑level and executive consideration.

This makes sense when you consider that every business function will now interact in some way with AI, whether that’s finance using automated payroll tools, HR using it to review candidate applications or machine learning being applied to enhance data analysis and information gathering.

As things stand, no single accountability model is dominating, although our August 2026 research revealed rapid growth of the chief AI officer (CAIO) title, with more than 20,000 CXO job titles on LinkedIn including “AI” or “artificial intelligence.” Several big-name firms have nailed their colors to the mast in this way. For example, Target and Deloitte have made headlines announcing CAIO appointments.

Whether it’s one CAIO or a select group overseeing AI usage, the prevailing question organizations need to consider is this: With whom does the buck actually stop? Does this new crop of CAIOs (or the boards, councils or CIOs given the responsibility) have genuine oversight and accountability, or, in reality, is it more fragmented?

For example, are decisions about AI in recruitment actually sitting with the chief people officer? Are commercial leads procuring AI sales tools without consultation? Is there a clear chain of command? To reframe Truman’s saying, it’s not just where the buck stops but also whether everyone knows where it does and is willing to adhere to this.​

The hope is that AI maturity will drive governance maturity so that as firms move from experimentation to widespread operationalizing of AI use, they’ll concurrently establish more formal oversight.
