An effective Center of Excellence is a standing enterprise capability, not a department and not a project. Stood up as a department, it becomes a silo; run as a project, it ends when the funding does. The job is to raise the whole organization’s capability and keep it raised — which is a different design problem than shipping any single system.
Three failure defaults
The IT Silo traps the capability in one team, so the rest of the organization stays dependent and nothing compounds. The Ivory Tower publishes standards no one adopts, mistaking authorship for adoption. And the Hollow Bench — the quietest and most expensive — automates away the entry-level cognitive work through which junior practitioners build judgment.
The Hollow Bench is talent debt. Automate the tasks that look inefficient, and you also remove the reps that turn a junior practitioner into a senior one. The bill comes due quietly, years later, when the senior bench you didn’t grow simply isn’t there — and it can’t be hired back on the timeline you need it.
What the operating model requires
A CoE that functions as a transformation engine needs literacy over competency — broad capability across the organization rather than deep skill hoarded in one place — plus standardized enablement and embedded expertise that sits with the teams doing the work. And it needs a clear line between build and govern, so the function that ships systems isn’t also the function that’s supposed to hold them to a standard.
The test: are practitioners developing senior judgment, or being hollowed out? An organization can post strong short-term productivity numbers while quietly failing this one — which is exactly what makes talent debt so easy to take on without noticing.
