The management and title structure in AS is a mess, especially on the larger accounts.
Cisco should do away with the "Service delivery executive" title, it means absolutely nothing, and the delivery managers do the actual managing of the services team. I guess the idea behind a SDE is to interact with the customer's upper management, but isn't that what the account manager does already? I'm not even sure the SDEs know what their role is supposed to be. The delivery manager and or PMs do all the actual managing, the NCEs do the work, and the SDE sits back and takes all the credit. Throw in a "Client services director" and it's clear that are multiple (highly paid) roles that overlap. It's a joke, because upper management on the customer side only knows/cares about the sales team anyway, not AS.
Solutions architect was another made up role in AS. The COE? Just a way to pool together resources so they could identify overlap across accounts and cut everybody else.
I'm glad I left Cisco under my own free will. If you are in AS, you should be very worried about the future prospective of your job. They don't care about your technical talent or the work you do at all. The only thing that matters is their P&L, not what your customer thinks of you.
