I don't know what WAI means, but note that I said discovered above. There's a separate conversation to get that work funded and that's where the managers come into the picture. Managers don't discover the work - they decide whether to fund the work.
I disagree. Have you never seen a manager hired from another place already come in with a bucket list they want to do bc “that’s how we done it at X”? That’s a classic. There are less nefarious examples of this ofc but ime managers absolutely do and even want to discover the work. Now whether they’re the right people to do it is entirely different question =)
