The gap the field keeps naming
Everyone describes the same fault line. Few make it the subject.
Read across the sources and a consensus emerges that the sources themselves rarely act on: strategy is seldom the problem. The operating model — the working system that turns intent into delivered, provable value — is where transformation breaks. Harvard and Deloitte put it plainly: a digital transformation succeeds only when the operating model is aligned to the strategy. MIT Sloan calls the failure the strategy-execution gap.
"The real killer is the gap between the slide deck and Monday morning."
And yet two things remain rare. First, the operating model is rarely made the actual subject of the work — it is assumed, described, or optimized around, but seldom changed. Second, when a program declares success, that success is rarely made provable: the field cannot even agree on the failure rate, because it has no shared standard for what "changed" or "worked" means.
