The funny part is, the document is not incorrect or misleading in any way. In fact its just the direct result of what these people have been involved with for a long time. But apparently we're not supposed to send them the truth, the whole truth, without shining it up for them first. Despite the fact they are equal partners in this we can't send them even draft information in an effort to help ease communication. And when this happens to us, and people won't send us the direct information or the "raw" data before polishing it for us first, we get angry. We get angry they dare slow things down and hold stuff back from us. We're adults, we can handle "draft" forms of stuff that we know might change, we're not going to forward it to our planning people and let them freak out over it.
But this apparently crossed the line. It's okay for us to be adults and see some raw data that might change, but apparently we don't extend the same benefit of the doubt to the other end of the line. We're afraid they'll really see how the sausages are made around here.
