  11. 11. IMS Approach <ul><li>APMG (Application Profile Management Group) </li></ul><ul><li>“ APMGs will be created after a final specification is released and overseen by the TAB Co-Chairs. A minimum of five Contributing Members (CMs) are needed to start a group. Those CMs that are actively developing, selling, or implementing the specification of interest and subscribers actively using the specification can participate. Only CMs can vote.” </li></ul>

Because there is ever increasing pressure on QTI scope... </li></ul>
