What are the different types of PRMs?

You may have heard about “pure play PRM” or “best of breed” systems, while there are more comprehensive systems called “Enterprise Channel Management (ECM)” or “Unified Channel Management” or “all in one.” However, even within these categories, there is a wide range of product capabilities to consider. Some vendors offer a suite of applications from which you can pick and choose modules to integrate into your PRM. Make sure you are clear if the various modules were actually built to work together, or if the suite is a result of a vendor acquiring a bunch of separate products and stitching them together to appear to be complete.
