I don't see anything necessarily bad in what's written here, but the document
seems to jump very quickly from the Vision statement into an itemized list
of what appear to be work items, without an overarching framework or story
linking the two. (Maybe moving the user stories up helps here, maybe not.)
It seems hard to measure success against the vision for the group, as
opposed to just measuring the success as 'implemented task/goal X'.

Also, while it says that "[t]his document does not dictate implementation
details", the tasks and goals section does go into the weeds, especially in
the SCL & DevAssistant sections.
