In the case of Procurement and bidding functions, the Contract Managers are to be well aware of supplier selection methods and criteria but within the contract management function. A best practice is to form a team with representatives from the key stake-holding functions, and design weighted criteria against which every candidate will be rated. 

Knowing how to prepare a clear Statement of Work, and how to draft the specific business terms and performance criteria that will apply to a particular agreement are critical skills for Contract Managers, whether preparing a purchase or sales agreement.
