There is a place and a time to be diplomatic, but today isn't it. You need to flex your muscles and take control. All of this nice stuff is keeping people from arguing, but it's not helping get anything done. You need progress, and to get it you need to push your agenda. Don't worry. People around you are going to be more receptive to your suggestions than you think. They're getting frustrated by the lack of headway too. Spring your ideas on them as soon as you can.
