All management needs to do is give a reason for optimism and that can be done by simply redoing timelines that are accurate and achievable so once they start hitting them progress will naturally be seen as being made.
It is a far better stradegy then not saying anything and when you do it is about how you missed or worse not say anything after you missed and leave it up to peoples imagination as to whats going on.Human nature in situations like POET always goes to the negative because when no one is talking its bad news, because good news is hard to contain.
Hopefully the 28th will be the start of good news
