  4. Progress during the week • Presentation 11-04/1009, the proposed framework, concerned many people • Right or wrong, many worried it required application level testing • After much discussion in meetings and offline, members of the group came to a common understanding • Both sides were saying the same thing but with different language! • Presentation 11-04/1131r1 proposed a metrics and test methodology approach for following 11-04/1009 • TG motions were passed to adopt the framework and approach of 11-04/1009 • Straw poll taken to see if people were in favor of document 11-04/1131r1 – unanimous acceptance C.
