Re: Wait for the evidence?
Some evidence:
BT Cornwall Strategic Partnership Review
https://democracy.cornwall.gov.uk/documents/s77905/Strategic%20Partnership%20Review.pdf
"KPI Measures achieved 185/289 = 64%", p3
"Delivery ... IT incident resolution having dropped from 96.6% in September 2014 to 70% in
February of this year ..."
From http://www.bbc.co.uk/news/uk-england-cornwall-34120656
A Strategic Partnership Review by the council in April said BT had promised it would create at least 197 extra jobs in Cornwall over the life of the contract.
It also said 111 of those would be delivered in the first two years, but only 35 had been created.
