Document how to communicate with clients when requiring feedback from stories
The handbook section on client owners currently states:
The client owner is responsible for handling most communications with that client.
Although some exceptions are presented below, this suggests that such communication should be escalated to the client owner.
However, as @Agrendalath mentions in this BB-4121 comment:
Usually, assignees do it by themselves after consulting the solutions with their reviewers
At the risk of over-specifying, it would be useful to have a short and clear paragraph describing what's expected.
I'm guessing the help
mailing list should also be included in those communications.
