TL;DR: Here is a 2-sentence summary:
The Open Source Initiative (OSI) has published takeaways from its recent board of directors election, which was marred by controversy and poor communication. The organization has committed to improving candidate selection and communication for future elections, including requiring candidates to sign an agreement at nomination time and providing more information beforehand.
The Open Source Initiative (OSI) has quietly published
"takeaways
" from its internal retrospective on the recent board
of directors election as an update
to the March blog
post that announced the new members of the board. The election was
controversial, in part, due to poor communication and OSI changing the
election rules and disqualifying several candidates after the election
finished. LWN covered
the election and results in March. The update commits to improvements
in communication and candidate selection:
What this election exposed was the need for the organization to also
assess whether candidates were fully eligible to run and prepared to
be seated on the board before voting begins. This is something we will
add to the election timeline next year. While we have not finished
figuring out all of the requirements for that assessment, part of it
will be asking candidates to sign a Candidate Agreement at nomination
time. We also have some ideas on ways for potential candidates to have
more information even before submitting a nomination.
In a related note, there is a petition
asking OSI to publish the "complete, unaltered
" results of the
board of directors election. Thanks to Josh Triplett for the tip on
the petition.

bottleneck for his use case. His proposed fix prompted a good deal of discussion
about how the data should be laid out.
