Docs are very, very strained. We scope docs to integrated only and we're
still lacking in quality, completeness, and speed of reviews.

At this week's extra TC meeting [1] we discussed only the difficulties with
integration and growth. I also want us to think about the cost of
integration with the current definitions and metrics we have. We discussed
whether the difficulties lie in the sheer number of projects, or is the
difficulty in the complexity due to cross-integration?

For docs I can point to "sheer number of projects" which is why we scope to
integrated only. But even that definition is becoming difficult for
cross-project so I want to explore the cross-project implications before
the "sheer number" implications.

One of the metrics I'd like to see is a metric of "most cross-project drag"
for all programs. The measures might be:
- number of infrastructure nodes used to test
- number of infrastructure jobs needed
- most failing tests
- incompleteness of test suite
- incompleteness of docs
- difficulty for users to use (API, CLI, or configuration) due to lack of
docs or hard-to-understand complexities
- most bugs affecting more than one project (cross-project bugs would count
against both projects)
- performance in production environments due to interlocking project needs
- any others?

We know nova/neutron carries a lot of this integration drag. We know
there's not an "easy button" -- but should we focus on the hard problems
before integrating many more projects? For now I think our answer is no,
but I want to hear what others think about that consideration as an
additional metric before moving projects through our incubator.

Thanks,
Anne
