We are a large organization and have many child organizations set up to represent departments. Each organization (department) has multiple assets representing sites or applications that the department owns.
We have some cross functional teams on our accessibility network in charge of creating best practices and procedures and monitoring things like different CMS options, procured software, in-house applications, etc.
Currently, there is no way to see a list of these types of applications/sites all together. You just have to know which departments they belong to and navigate to them separately and we're not just talking about one or two assets to track.
I would propose some sort of labeling functionality to add a label to assets, such as "Internal App", "Third Party App", etc. and then display a dashboard with those assets so that we can more easily figure out what kind of guidance we need to provide, best practices we need to create, problems we need to address, etc.
