    • Prioritize payments use cases and the capabilities necessary to fulfill them.
    • Review draft charter(s) and plan for first round of standardization
  • Initiate discussion on other IG activities (to follow push towards launch of standard(s) groups).
  • Solicit feedback from broader community on group's direction (via the roundtable)
