The most common mistake is treating AI strategy as a technology selection exercise. 'We need an AI strategy' becomes 'we need to choose a platform and run some pilots.' This skips the most important step: understanding where AI actually changes your competitive position.
An adoption plan answers: what AI tools should we use? A strategy answers a fundamentally different question: how does AI change the economics of our industry, and what do we need to do about it?
I've seen this play out with painful predictability. The CEO reads an article, attends a conference, or gets spooked by a competitor's press release. They tell the CTO to 'develop an AI strategy.' The CTO assembles a working group. The working group evaluates vendors. Six months later, there's a PowerPoint deck with a maturity model, a roadmap of pilot projects, and a budget request. The board approves it. Eighteen months later, none of the pilots have scaled, the budget is spent, and nobody can articulate what the organisation actually learned.
The problem isn't execution. The problem is that nobody asked the right question at the start.
