Aspect-Oriented Modeling (AOM) is a design technique in AOSD which attempts to separate crosscutting concerns in the earliest steps of software development.

Join Point Designation Diagrams (JPDDs) are means that visualize join point queries graphically and separately from the adaptation specification. They provide a visual means to constrain the selection of join points based on static and dynamic, structural and behavioral context. Based on the latest researches on JPDDs, it has been lacking of support in procedural logic by JPDDs such as loops, alternative structures, and conditional branching between object interactions in the selection criteria of the join points. It causes some join points could not be modeled by JPDDs when join point specifications get complex in aspect-oriented programs. There is another issue in JPDDs which is lack of supporting timing constraints in the join points. There is no way or notation to visualize any timing constraint in a JPDD.
