All very interesting but...
Suppliers will just deliver less or worst just use less experienced and cheaper staff...so who actually wins here? Why not ask for a change in company ethos so that when working for the public sector companies do not use inefficient & ineffective methods for delivery & support just to expand revenues? Seeking across the board savings is an admission that Government does not have access to the right skills (people) to negotiate and formulate appropriate contracts. The worst thing is that we all lose here - we are all tax payers and users of Government services (but the large IT suppliers really don't care).
