For the way we do it, when a stakeholder wants our team to do something, they come to us with user stories and acceptance criteria that matter to them. Then we hash out the rest of it. I don’t really see a useful way we could be trusted more. The Marketing department knows best what feature it is they want on the website, and why. So they specify that part. We estimate complexity and the business weighs the priority of that feature against other stuff in our backlog and it falls into an appropriate sprint based on that and other motivating factors. Then we do the work.
I don’t see a lack of trust? So I’m curious where you see it and feel it should be done better?
