This is a great summary and would also explain the tendency to want to meet in response to a thought out document. The author has wrestled with the topic long enough to write out a specific document. The receiver of the document has not yet spent this time, and needs to understand broad outlines. Besides this, if there is a meeting of equals, they might bring something to the table, the author hasn't thought about, or did but dismissed it for undocumented reasons. Let alone the buy in factor of a shared product vs 'you go build this, off you go'

I hate meetings for looking busy, but a 20 minute conversation can bring a week of work to actually implement the decision.
