Hi Rooney, thanks for the suggestion (and thanks to Aaron Baca on the Analysis tool side of things for helping with this answer!) The Standards cannot be rolled-up, because of the way they are framed, i.e. each has to stand on its own, primarily because of the difference in scope, functionality, features, etc. of the tool sets defined in each Standard.
I do like your suggestion where you state: “encourage departments/decision makers to take a look around and scan the environment before making purchases for tools that may already exist on campus.” which I believe is implied throughout the document, but perhaps could be more clearly stated.
We know Purchasing does the kind of review that you describe wherever possible to help with the search process, but we don’t have much direct information. We can follow up with Purchasing to find out more about that process.
