I disagree that bill code is the most scientific way to measure it. Bill code reflects the cost to staff, and therefore will be lower for the equivalent grade in Solutions and Services because of the generally lower comp. (Incidentally, I didn't say that mobilisation wasn't in the Services workforce - I said it was the consulting arm of Services). A Solutions M1 might have a bill code lower than many C3s, but they're still a Manager.I'd also add that Level Bs get the car allowance, bonus scheme etc that is only available to Manager and above in Consulting.Anyway, I'm not sure what the disagreement is now, since you've now contradicted your previous point and said that Level B is Manager in Services... which was my point, and contrary to your earlier statement that it was equivalent to C3/M1.
