Three examples (IMHO) of waste, and a personal whinge:
1. Recently (certainly same total numbers - say 52K) we had 6K blue-suiters in HQs various. Who else would have 12% of its staff in Head Office?
2. I run all my insurances (house/car/travel etc) on line, and also pay bills to anybody from Pprune

to British Telecom, credit cards etc. Makes life easy when deployed, so why do I (even as a relatively senior person) need signed hard copy for my travel claims. A question (answer at bottom of post): Cisco the computer people employ 35k people world wide. How many staff process their travel claims (on-line of course)??
3. I can accept the need for PTIs even (or perhaps particularly) when deployed, but I have some difficulty with PEdOs. We do not commission firemen (sorry PC Police - I mean firefighters) we let Ops Support run them. So why can't Admin (Trg) run PTIs?
4. Number of ranks - too many. The Met Police have 35k personnel, and have only 9 or 10 (IIRC) ranks - and they all must go through all the ranks! And was my leg being pulled or are we REALLY going to have WO2s and L/Cpls in the RAF as a sop to Jointery?
Oooooh I feel better for that - rant over, but questions I frequently ask and to which I have received few answers.
....and speaking of answers ..... Cisco manage the worldwide travel claims for a 35K workforce with .... er .... 12 people!!
