Contract Management Framework

I am currently drafting a contract management framework for our business, trying to provide staff with some guidance on what good contract management looks like for different purchases (consultancy vs maintenance vs consumables). First step is to create some standard language so that we can all be clear who is responsible for what. I looked at the CIPS website, but that just seems to have a sales pitch for POD and some standard T&Cs. How do you refer to internal stakeholders in relation to contract management? Particularly those who manage the contract day to day vs those who are accountable for the success (or otherwise) of the contract once awarded? Or can you link me to an industry standard so that our definitions can be recognised by other companies as well?
