Pardon the late reply. Went to Rio to take in the carnival. Met (or saw) Megan Fox. Looks rather plain in real life! Anyway.....The CT role is what it says on the can - cost reduction. In MC, it's not the most glamorous of roles/projects. The same in industryIn telecoms, you really need to understand the underlying technologies and how you monetise them.The CT group is essentially BT's internal 'cost' consultancy. Operator revenue is down and will remain down, as illustrated by a top fund manager letting go VF shares (lower dividend, etc.). So, it's cost cutting (or "cost transformation").To understand the root of this, you really need to understand what's happening in this space. You can only achieve so much by doing things like moving some service centres to Malaysia and Latin America, etc.You'll probably do projects on a BU basis, e.g. BT Wholesale, Global Services, Openreach possibly, etc. Then again, you might get stuck with a single BU. I think Wholesale / BTGS have had their 'cost transformation, from procurement to whatever. Retail is plain boring. Enterprise? BT face a lot of competition here. Way better players! More nimble players.You will find it very difficult to do anything in BT. Just far too much nonsense / politics.You will rarely get the chance to see the big picture, but instead, will do your own bit, which to me, is not the right way to go about things.I just can't see a role in Cost Transformation offering you the chance to be a proper specialist.Then comes the 'culture' thing. I've worked and had projects with a number of incumbents, e.g. BT, DTAG, etc. BT is possibly the worst of the lot.
