Sure Step Business Modeler

Microsoft provides an awesome tool known as Sure Step Business Modeler that partners can use to have their customers visualize how Dynamics Customer Model is synced up with hypothetical or their own business processes. The tool itself is really simple to use (IE like controls) and user can easily add, edit new departments, personas, business processes, org charts to meet their own needs. You can also attach JPEG images like flow diagrams with each process, sub process, task etc to further explain the process in detail.

I found this tool extremely useful when customer want to see how their business processes, employees and organization will work with the proposed Dynamics solution. After you download the tool from PartnerSource, you can install it either on a single machine (with DB and client application) or centrally with DB installed on a separate machine with multiple clients accessing it.
