So we ave 3Dmarkup in PCS which everyone gets. That can view, markup with slides and display clash information. All good stuff.

We also have "Digital Mockup Validation Engineer (DEY)" This gives the CATIA side of things to create the markup.

But now we have "Digital Mockup Review Manager (RED)", "Digital Mockup Review Engineer (DRN)" and an new role "Digital Mockup Validation Manager (YED)" at 22x. What is the difference between all of these and why do we need so many? Why isn't reviewing part of the basic role?
Can we get a matrix to display the functionality of each role so we can compare. This is important for customers to understand what extra button they are getting for the money they are paying and is it worth it when most of the functions come as standard in 3DMarkup.
