6. Even if the acquisition team are under pressure of time, for example from the need to meet the ISD or because of bid cost concerns, the lessons have been repeatedly learnt that leaving material elements of the deal unresolved at this point is counter-productive. It will take more resources in the long run, and could well result in a less satisfactory deal. It has been seen time and again that attempting to negotiate even small improvements to the Authority's position after the preferred bidder has been appointed (as given, say, in the Best and Final Offer response) is fraught with difficulty.
7. At the same time, the acquisition team should not prolong the competitive process and oblige bidders to keep bid teams in place when in reality the choice of a preferred bidder can be properly and sensibly made. It is seen as good practice to de-select bidders who are highly unlikely to win the competition as soon as this fact becomes clear. However, the need to retain a viable and sustainable competition must be a primary consideration.
