X12 is led by the X12 Board of Directors (Board). The X12 Board and the Accredited Standards Committee’s Steering group (Steering) collaborate to ensure the best interests of X12 are served. Each group has specific responsibilities and the groups cooperatively handle items or issues that span the responsibilities of both groups.

External liaisons represent X12's interests to another organization as defined in a formal agreement between the two organizations. More information is available in X12 Liaisons (CAP17).
