Ok, if you have read past blogs of mine you know I am not a big fan of constructive criticism or 360 degree feedback.
Furthermore I don't think you should run your best ideas past a committee! That can often include co-workers, family members or people on the street.
If you have a great person or a great idea, it sometimes needs to be insulated from the crowd think.
It needs to be held at arms length from the well-meaning good advice of people whose major claim to fame is that they have an opinion.
Solicit an opinion only from those whose opinion you respect.
Don't ever let turkeys judge eagles. It will get messy.
