MBAs and executives are fungible. All the MSPs out of India have rotating executives and they pretty much run the work they are doing for EM. It’s just a bit of a step to start moving EM executive positions to India. The talent pool is global and EM could easily fill those roles and have them work out of Bangalore. Houston is overpriced for executives with little return and value (if any).
As an aside, I was searching for a contact on the CC org chart and I found one L4 who had one direct report (his peers had 10 or more) and his direct report had about 10. If ever there were a blatant example of fat in middle management (figuratively and literally) this was it. Cut that fat, send both the L4 and L5 managers’ positions to India and send signals to these guys to finally retire. We do this all the time with all other positions, executives should be no different.
