Hi SFlannery ive worked in Call Centre,s for the last 7 years and have always used both Input and Output Spec,s ,they are the basis of the contract, they clearly define the services that is provided, they clearly define the clients expectations,they allow you to prepare work plans, schedules, and periodic cleaning charts, and they can provide you with an oppertunity to charge for variations, provide them with your Service Level Agreement and the client is well impressed Good Luck
