Yes, Sam, as indicated to you by separate email, there are multiple business cases and material available in our IACCM library, as well as in our "Contract and Commercial Management: The Operational Guide - E-Book" with valuable information to respond to your question. The Contracting body of knowledge and IACCM programs provide us with a solid understanding of the best practices to identify consistent tools, processes and methods. Also, there are previous postings in this forum related to Contract Management software tools which could be relevant in the search and analysis of not only sell-side but buy-side business as well.
Regards,
Pablo
