The industry's one big idea has expired.
For thirty years the services industry has run on a single big idea. Shift left. Push work towards cheaper resolution, automate more, deflect more, keep humans away from demand. It was never foolish. In a world where every fix cost you an hour of somebody's time, it was sensible arithmetic. The problem is what happened next. We took an optimisation and made it doctrine, and once something's doctrine nobody asks whether it's still the right answer. They just ask which version of it we're on.
Then AI turned up. And it didn't beat shift left at its own game, it made the game pointless. When software can spot the problem, decide what to do and fix it before anyone notices, there's no left left to shift to. The cost question is busy answering itself.
Which leaves the question shift left was never designed to answer: where do human beings create value that nothing else can?
That's the Human Operating Model. Not a framework you can get certified in. An argument about how services should be designed, sold, delivered and led when software does the running and people do the differentiating.
