That's the single threaded part, but it is also meant to be the proper "owner" in order to move quickly, but the bigger organizations get, the less that part ever actually happens and instead you get decision by committee which is inherently slow and usually sub-optimal since all decisions are negotiations. This is also where my favorite jeff b. quote comes into play (though it is sadly ignored more and more nowadays): "even well meaning gatekeepers slow innovation"

Ah; thanks, that makes a ton of sense. We've struggled with both "halves" of that phrase at different times, but recently we've done better on the O and are still weak on the ST part, so I was overly-focused on the most acute painpoint for us.
