Operating committee
An operating committee, so sayeth https://www.chron.com/, does not oversee day-to-day operations, but rather deals with operational functions from a strategic level.
The steering committee, between them, decide where to steer the car. The operating committee decides how to steer it. and the good old subject matter experts - assuming they have not all been made redundant — actually turn the wheel.
It is one bulwark the benighted SME can rely on is that at some point middlemanagement can't lay everyone off, because someone in the service line has to touch the steering wheel, and it sure as well won’t be anyone on an opco or a steerco. Because it is not in their service catalog.
And besides, touching the steering wheel — manual labour in the modern world — gives you redundancy risk. And you don’t go there, girlfriend.
