Other drafts of interest ● As usual, majority of meeting time allocated to WG documents ● Other documents get agenda time based on level of mailing list discussion and issues requiring discussion ● All agenda requests, with links to docs, are logged at:. ● Other documents of interest (not requesting agenda time): ● draft-elwell-sipping-update-pai-01 (Note relationship to draft-munakata- sip-privacy-clarified-00) ● draft-sinnreich-sip-tools-01.txt ● draft-holmberg-sipping txt  Completing chartered work (including detailed reviews) makes room for discussion of new work items.

How to meet WG milestones more efficiently/effectively ● Over the past year, we’ve been less than 50% accurate at meeting milestones. ● Some delays are due to dependencies on other docs. ● Other delays due to lack of cycles on behalf of doc editors. ● Other delays could be attributed to newness of WG milestone tracking in spreadsheet.

How to meet WG milestones more efficiently/effectively ● Proposal on list to move delayed docs to end of queue to avoid ripple of milestone changes: ● Mailing list feedback thus far has been supportive. ● This model is reflected in some of the updated milestones proposed.

How to meet WG milestones more efficiently/effectively ● Other options: ● More regular pings from chairs on upcoming milestones (not preferred by chairs given accessibility of information in spreadsheet). ● More regular updates (bi-weekly) of spreadsheets to prompt doc editors (including doc editors Name in the summary and cc’ing doc editors) ● Longer term, tools that would automatically generate s to doc editors with updated dates (ala tools for docs post-WG).
