Hi Catherine, Thanks for the response.
I fully understand the rationale for the time interval between M0 and M3, and I don't think there's much opportunity to improve on that. My point was more related to this statement: Nothing prevents any project team from handling multiple releases at the same time, from self-releasing their project any time, from continuously developing and testing without breaking the gating, etc. My sense is that while this is in principle true, in practice I don't see any evidence that the culture of doing so is being developed. My proposal below is a suggestion on how we might reflect that this is desirable in the actual time plan, potentially by introducing a specific - weekly, for example - "snapshot build" that projects could be encouraged to release to periodically. Do you feel that you could work with David/PLTs in order to build a transformation plan in alignment with your expectations? Yes, I think from Ericsson's perspective we would like to improve on this, and myself / Magnus would be happy to engage on helping to create a proposal.

We welcome any suggestion to reduce the time between M0 and M3. The current assumptions are that 1. Istanbul release might shift a little bit during the testing cycle 2. Project teams can hardly handle multiple releases at the same time (i.e. we are nearly there to complete Honolulu Maintenance after several months) 3. Critical developers/testers might take vacations or/and will be barely available from Nov 22nd until the second week of January 2022 4. A lot of events in January - DDF, Chinese Holiday, Epiphany, etc. Concerning your second request, Honolulu was the first prototype release for the new release cadence. Istanbul has been re-adjusted based on the lesson learned from Honolulu. Nothing prevents any project team from handling multiple releases at the same time, from self-releasing their project any time, from continuously developing and testing without breaking the gating, etc. The Jakarta milestones have indeed been defined to ensure that the ONAP Community will deliver a consolidated certified content at a certain moment. Nevertheless we are always open for any suggestion to improve the release cadence. Do you feel that you could work with David/PLTs in order to build a transformation plan in alignment with your expectations?

Before we vote to approve (or not) in the TSC meeting tomorrow, could we take a brief discussion on potential clarifications that could be made. Specifically, while there is a long period between M0 and M3 / M4, projects should be encouraged / expected to make regular small incremental deliveries into integration, to de-risk the chance of a big-bang approach impacting our timelines and individual's personal wellbeing towards the end of the project cycle. One proposal could be to introduce a specific, regular integration / release train approach, that individual projects are expected to regularly deliver into - something like this conceptually: [cid:image001.jpg@01D7B5E8.FE110F50] This would mean - assuming most projects caught the train a few different times during the release period - any potential issues can be caught early, isolated and triaged before causing a bottleneck. Is this something we can discuss for inclusion in the release schedule?
