My current idea is merging work related to this task and T154321 for a team goal for next quarter.

1. What is the problem?
2. How does success of this task look like? How do we know when we are done?
3. Is there any goal, program, project, team related with this request? Please provide links and use the corresponding Phabricator tags when available.
4. What is your expected timeline from start to end? Is there a hard deadline?

So far these are the questions we're thinking about. They're being piloted already - https://phabricator.wikimedia.org/T166895 was filed following the process for example.

Another example, showing what happens when the questions are added as part of an initial discussion: https://phabricator.wikimedia.org/T167815#3345363

At least in that case the system also works. Good!

(Would this end up as a section on https://meta.wikimedia.org/wiki/Community_Liaisons#Contacting_us ? )

Probably, yes, as I've already felt the need to link to those more than once and dislike using links to Office on Phab and wikis.

If we have it in Meta (or somewhere public), then we run the risk of receiving support request from... anywhere. I think this is an ok risk to have, probably no requests will come, if there is an exception perhaps it makes sense, and if we get requests that don't make sense we can always decline them.

I think that if we specify that's a protocol for WMF teams to follow or something, people would understand that? We don't really get requests from Meta or other community channels.
