Hi all,

The ASF board suggested that we (Beam) share some of what we've been doing
for community development with dev@community.apache.org and
memb...@apache.org. So here is a long description. I have included
d...@beam.apache.org because it is the subject, really, and this is & should
be all public knowledge.

We would love feedback! We based a lot of this on reading the community
project site, and probably could have learned even more with more study.

# Background

We face two problems in our contributor/committer-base:

1. Not enough committers to review all the code being contributed, in part
due to recent departure of a few committers
2. We want our contributor-base (hence committer-base) to be more spread
across companies and backgrounds, for the usual Apache reasons. Our user
base is not active and varied enough to make this automatic. One solution
is to make the right software to get a varied user base, but that is a
different thread :-) so instead we have to work hard to build our community
around the software we have.

# What we did

## Committer guidelines

We published committer guidelines [1] for transparency and as an
invitation. We start by emphasizing that there are many kinds of
contributions, not just code (we have committers from community
development, tech writing, training, etc). Then we have three aspects:

1. ASF code of conduct
2. ASF committer responsibilities
3. Beam-specific committer responsibilities

The best way to understand is to follow the link at the bottom of this
email. The important part is that you shouldn't be proposing a committer
for other reasons, and you shouldn't be blocking a committer for other
reasons.

## Instead of just "[DISCUSS] Potential committer XYZ" we discuss every
layer

Gris (CC'd) outlined this: people go through these phases of relationship
with our project:

1. aware of it
2. interested in it / checking it out
3. using it for real
4. first-time contributor
5. repeat contributor
6. committer
7. PMC

As soon as we notice someone, like a user asking really deep questions, we
invite discussion on private@ on how we can move them to the next level of
engagement.

## Monthly cadence

Every ~month, we call for new discussions and revisit ~all prior
discussions. This way we do not forget to keep up this effort.

## Individual discussions

For each person we have a separate thread on private@. This ensures we have
quality focused discussions that lead to feedback. In collective
discussions that we used to do, we often didn't really come up with
actionable feedback and ended up not even contacting potential committers
to encourage them. And consensus was much less clear.

## Feedback!

If someone is brought up for a discussion, that means they got enough
attention that we hope to engage them more. But unsolicited feedback is
never a good idea. For a potential committer, we did this:

1. Send an email saying something like "you were discussed as a potential
committer - do you want to become one? do you want feedback?"
2. If they say yes (so far everyone) we send a few bullet points from the
discussion and *most important* tie each bullet to the committer
guidelines. If we have no feedback about which guidelines were a concern,
that is a red flag that we are being driven by bias.

We saw a *very* significant increase in engagement from those we sent
feedback to, and the trend is that they almost all will become committers
over time.

## Results

 - Q1 we had no process and we added no new committers or PMC members.
 - Q2 when we tried these new things we added 7 committers and 1 PMC
member, with ~3~4 obvious committer candidates for next time around, plus
positive feedback from other contributors, spread across five companies.

We've had a pretty major uptick in building Beam as a result.

## Review-then-commit

We are dedicated to RTC as the best way to build software. Reviews not only
make the code better, but (with apologies to ASF/GNU differences) as RMS
says "The fundamental act of friendship among programmers is the sharing of
programs" and reviews are where we do that.

As a minor point, we also changed our "review-then-commit" policy to
require that *either* the reviewer or the author be a committer. Previously
the reviewer had to be a committer. Rationale: if we trust someone as a
committer, we should trust their choice of reviewer. This also helps the
community, as it engages non-committers as reviewers.
