Oh man, this is so irritating. I've been pushing for changes for years, and told, "No, it can't be done!" Then the New Guy comes in, recommends the same damn thing, and suddenly management is like, "Hey! That's a good idea!" I mean, I'll take the win since the change finally happens, but what a great way to demotivate your existing staff.
Near as I can tell, this has to do with how many different people a problem has been reported by. Either strict numbers or turns of phrase finally changes the mind of the holdouts.
I started sending people to ask the person who has been vetoing the change about why we can’t have nice things. Sometimes it works.
