Either on the figure itself, be means of arrows, or in text. One is to explain the placement of the "project". It seems like their position carries information, but it is not 100% clear. For example, EBM seems to facilitate interactions between 1. and 2. DEQM is facilitation interactions between 5. and 6. However, it is not clear from the Figure if CDS Hooks is something specific for 3. or 4. or for some interactions? Also, is QM IG something related to 5.? What about CQL, QI Core, and CR. They say that a picture is worth a thousand words. Yet, the picture is to be clear for understanding. In the form it is now it is not very clear.
