[MeeGo-pm] Release 1.2 MM3 - to be or not to be ...

I'll give a hypothetical example of different target platform schedule.
Target platform power-on is Feb 22, 2011 with MX2573 chipset.
Power on drivers for the MX2573 chipset are available from vendor on Feb 1,2011, these drivers only run on the MX2573 and no other chipset.
Other IVI specific critical components that interact with these drivers and provide IVI services not used on other MeeGo platforms.
Target platform Alpha deployment to key customers is April 22, 2011-02-02
I have 20 developers, RE and QA dedicated to integrating, testing, debugging and fixing these new drivers and critical IVI specific components during the power-on to Alpha phase of this platform from Feb 22, to April 22.
Under the current process definition, I can't use the meego build server to support this platform for approximately 3 months of the 6 months release cycle from the time of "feature Freeze" through the RC build when the Trunk is forked and probably for another several weeks until the Trunk team finishes the final release and gets around to completing the Trunk merge window updates and produces a new stable Trunk. For example for 1.2 the only time I could integrate new IVI features was 2 months from late November to late January. Hardware schedules do not always line up with the MeeGo open feature window when it is only 2 months out of every 6.
I'll give you a hypothetical example of different objectives.
For MeeGo IVI 1.2 we might:
have no vendor planning to ship product based on MeeGo 1.2
Application quality is set to "Sample Demo" quality, not "Reference" or "Product" quality
Request from customers with deployment plans in late 2012 for demonstration of capability and flexibility to integrate their proof of concept demos in March in order to meet customer milestones for continued commit to product in 2012.

> I agree that the code bits that run on all platforms should have common milestones and exit criteria. But the original poster went on to specify milestone exit criteria for bits that are not common, that are specific to verticals. These are the elements that I believe should be subject to milestone and exit criteria set by the vertical PM, development, Release Engineering and QA. Verticals have different requirements for level of maturity and quality, depending on their release objectives, target platform schedules and key customers.
I guess the interesting question is if whole project moves to MM3 or
only some parts of it. Since MM3 still allows work to be done through
CCB (see further down), why shouldn't this be enforced across the
When I speak about milestone criteria, this is
http://wiki.meego.com/Release_Engineering/Milestones#MM0 - which is
very generic for fitting the MeeGo requirements process, the QA
process and release process.
> For example if IVI has an application that sends a message via the automotive network services stack over MOST bus to set the configuration of the heating and air conditioning unit in the car, the IVI team may well decide it is OK for this application to first appear in a build on Feb 22, roughly one month after the "Feature Freeze" defined for the core. Since these bits will never run on any non-IVI device, this decision should be made by the IVI team and not blocked by other devices or the core team.
This problem usually happens in Core and Handset too, though :) Core
CCB [change control board?] or Handset CCB (usually the vertical's
release management , architect, product manager, program manager, QA,
etc) gets together, judges what risks there are to letting things in
past freeze into their vertical or to Core. The goal is to make a
release in the end without too many bugs. So I would expect a IVI CCB
to exist too that enables this kind of thing.

This one I'm a little worried about, is it possible for you to
elaborate on what different objectives for quality, enabling, target
platform schedule exist for IVI? And what problems do you see with
I mean, we should release every 6 months exact. Test cases are worked
out together by vertical's PM and QA anyway for the requirements
specified on the roadmap and usually bugs end up being marked as
release blockers or not, effort put towards them.. and a release of
MeeGo (Core + verticals + etc) comes out, hopefully not too broken?
Reaching for "# No major and critical bugs present, # Moderate amount
of normal and minor bugs present, # No major performance or
reliability issues open " isn't unreasonable for shipping code, at
The problem with if you're out of sync is that it gets difficult for
you (IVI) to get things admitted to Core, for instance, if there's
such a need when Core is in deep freeze and you're only in MM3,
updated developer documentation and so on and making the deadline of a
