A programme manager who has delivered in a retail bank knows what a model risk sign-off is, why the change advisory board meets on a Thursday, and how long security clearance takes. A generalist recruiter cannot assess for that, because they do not know to ask.
Working in one sector also means our references are useful. When a new prospect asks who else we work with, the answer is a list of institutions they compete with, regulate alongside, or sit next to on an industry body.
And it means we understand the constraints that have nothing to do with technology — the vendor onboarding process, the procurement panel cycle, the transformation targets, the POPIA obligations that follow a consultant onto your systems.
