Now, unhelpfully, I am out of office this Thursday and Friday (at a
folk festival), so these 2 hour meetings, just don't work for me this
time :(

I was thinking of trying for the next PWG meeting that I am able to
attend, and discuss things together in that? Where is the wiki page
for all those meetings, I couldn't find it, for some reason?

Thanks,
John

We are working to complete the list of user stories for our pilot, with input from Operators by the end of next week. Our plan is to review that in the cross-project team meeting the week of 8/24 (haven't asked for agenda time yet). Do you think it will make sense to review the Nova related user stories in a Nova team meeting that week too? I'm sure it would be very helpful for the gaps analysis around each user story.

Its just if the list ends up getting ignored by the developer community, the process is still a good stepping stone to where there is more cross company collaboration at the product level.

>>> [ST] +1.  The product WG is planning to pilot a "workflow" that spans the sequence of events leading from documenting user stories from various sources all the way through engagement/collaboration with the developer community.  We plan to discuss the available user stories next week and, hopefully, determine which ones we can use to "pilot" the process.

>>> [ST] We might have limited bandwidth to really dig in at the moment since we are "piloting" the process through the Mitaka design summit, but we would be glad to help where we can!  The current plan is to review a set of initial user story submissions next week, identify team members to help coordinate them, share our list with the community for feedback (the prioritization process will change in the future but we opted for a lightweight weighing exercise for the pilot), perform a gap analysis to determine which areas/projects map to the user story (this is another potential area for collaboration with the development community), join developer team meetings to share user stories/context to get feedback and forge partnerships, and be available at the design summit to participate in discussions for those user stories that require further discussion.
