11. SIPish Work Issues Increasingly dependent on most-active contributors Increasingly hard to make new contributors productive More topics to address than we have energy to address Complaints that WGs are closed to new ideas Complaints of "Insider Control"

12. Facts of the Matter The "New" has worn off and we are down to the hard work of finalization. Many long-term contributors are focused on closure, not on new ideas. The history of SIP standardization keeps getting longer, increasing the gulf between older and newer participants. The Charter constrains our range of interests and many new ideas are out of scope. (this is both a blessing and a curse) Standardization in some areas is ahead of implementation

13. Impact Long-term contributors burn out, increasing the load on and delaying the work of the remainder. New contributors feel either rejected or overwhelmed, take their energy elsewhere. Specifications linger in "almost finished" state.

14. Proposals Prioritize Work Items (see also next slide) –Priority for sending drafts to IESG –Priority for progressing new work Establish Mentoring and Training –Internet Drafts with a mentor or shepherd –Frequently Asked Questions "Push Through" to Closure Reorganize ? –Split the Working Groups –Adjust Charters –Change or Add Chairs –Formalize Design Teams as Sub-Groups

15. How do we prioritize early work? Grade for interest, complexity, and likelihood of getting implemented Easy, interesting things should get priority

16. Status Transcoding - Focused interest from design team Session Policy - Tons of Interest, but hard Conferencing - Lots of Interest, need to push to finish Exploders - Much interest from OMA, requested by SIMPLE Location - Easy, requested by GEOPRIV Remote Call Control - Interest from Enterprise IP Phone folks Emergency E2M Security Role-Based Authorization Digest Authentication - Another place we dropped the ball Billing Issues - Important, Interest in Past, no recent drafts
