Business Process Model for Fluid Expenses?

We are looking at transitioning to the Fluid version of Expenses, and were wondering what materials that support the high-level business model. From what we can see it is oriented differently, and we like it, but I haven't found something in PeopleBooks, MOS, or on the community that fits the bill like the old business process models had. We have the current ERDs, and these seem still largely accurate, but it would be nice to see the Business Process Models that we have had with prior versions. Is there something that comes close to this?

Thanks.
