Why did [mistaken action] seem like the correct action at the time?
Why was the problem not detected automatically?
- Why was the mistake caught late, not early?
Why was the problem not fixed automatically?
- Why did this require manual intervention?
- Why did this require human detection?
Were any of the contributing factors already known problems?
- Why were they not addressed earlier?
- Have we seen these in previous RCAs?

Have the following been addressed in the branch, if appropriate?

Tests (unit, API, integration)
Docs (source comments, doc directory, elsewhere)
Changelog
Compatibility with previous versions (calls, shared files or DBs, data formats -- backward and forward compatibility)
Rollback friendly?
Feature switches?

edX-specific considerations:

Where do the different docs live?

	# every open edx-platform PR to let people know that they needed to
	# rebase onto master (or merge it into their branch) to avoid breaking
	# the build.

	# The script requires a Github access token and finds all open PRs
	# against master on edx-platform which do not have a specific commit
	# in their ancestors, then leaves a comment on each one. This should
	# be done from a bot account; the bot will then be subscribed to all
