The $1 to $10 rule that breaks every AI business case.
I spend a lot of time advising businesses on AI adoption. The conversation almost always starts with software pricing. It almost never ends there.
This piece is built on enterprise AI deployments across logistics, telecom, professional services, and technology. Every number below comes from that report or the published research it cites.
Executives keep budgeting AI like they budget SaaS. Pick a vendor. Approve a licence. Add some implementation hours. Wait for the productivity gains.
Stanford's data tells a different story. When researchers asked 50 practitioners what was the hardest part of their deployment, 77% of the answers had nothing to do with the model. Process documentation came first. Data quality came second. Change management came third. Technology was consistently described as the easiest part of the work.
The macro picture is worse. Accenture estimates that 80% to 85% of companies are stuck in what they call a Proof of Concept Factory, running experiments that never scale and absorb the budget anyway. McKinsey's State of AI research shows that high performers, the organisations attributing more than 5% of EBIT to AI, are not the ones with better models. They are the ones rewiring their processes and data products.
What is the right ratio? Erik Brynjolfsson's productivity J-curve research found: "For every $1 of tangible technology investment, companies spend up to $10 on intangibles, process redesign, reskilling, and organisational transformation."
That is the rule. One to ten. The model is the cheap part. The deployment is where the budget goes, and most CFOs never see that number on the proposal.
Sixty-one percent of the AI projects that succeeded were preceded by a failed attempt at the same problem. The failure was a sunk cost that never appeared in the successful project's ROI calculation, but it was usually essential to it.
