Points to consider
After the appointment of a preferred bidder, it may be difficult to maintain competitive tension. Since competition is the best driver of value for money, great care needs to be taken that the appointment is not made prematurely
Are the key elements of the deal agreed? What is the risk it could unravel?
Can the preferred bidder demonstrate before appointment that it has the resources, and management skills and support to conclude negotiations on the basis of the agreed key elements in an efficient and professional manner?
Does it have the ability to deliver, post-contract signature, a complete solution to meet the output specification?
