Postmortem and lessons learned for Linaro's release 2012.02

 https://wiki.linaro.org/Cycles/1202/Release/Review


Highlights and Key Successes
============================

By using proper image builds and validation with LAVA the Linaro
Developer Platform can ensure all images are properly tested as soon
they are published. A new proposal for the linux-linaro tree was
introduced which will make the linux-linaro tree the single reference
for kernel work at Linaro and should always be working against latest
upstream RC release.

The Linaro Developer Platform team will now be responsible for
packaging and maintenance of all the LT kernel flavours.
Responsibilities will include validating the kernel daily with LAVA,
and only publishing the kernels (which pass validation testing) to be
used by the LEB images (until the new linux-linaro tree is in place).

During February 6-10 Linaro hosted Linaro Connect Q1.12. Rounding
out the event were daily plenary, planning, and hacking sessions which
attendees were encouraged to attend and take part in. This event was
the largest Linaro Connect to date and was highlighted by the
participation of community members and other external attendees,
notably from Google. The event also hosted "Demo Friday" where once
again the public was invited to participate in hands-on demonstrations
of Linaro developments. Some demos can be seen on Linaro's Youtube
channel:

Linaro was also well represented at Embedded Linux Conference with
a very high percentage of presentations given by Linaro team member
or seconders.

Postmortem and Lessons Learned
==============================

This cycle was the shortest that Linaro release has encountered, and
this presented some challenges. The small number of development and
planning days, along with interruptions by Linaro Connect, ELC and ABS
contributed to a smaller production of deliverables from the team.
There was a loss of focus as people dealt with fractured development
cycle, jet lag and the shorter work sprint.

A solution discussed to mitigate this problem is that for short cycles,
a different type of planning should be applied that is focused more on
bug-fixing and the backlog, rather than larger ambitious deliverables.

The Android team has been doing a large amount of kernel development
and has suggested the addition of some sort of kernel resources for
iMX53, Origen and, possibly Snowball.
