Welp, that happened.

Let it be known on this day that I told my boss that I thought we needed to slow down and do some actual planning for this project. She expressed shock that no one knew what they were doing and refuted my claim that some depts. had been told certain things.

Then claimed that planning was for "waterfall" which is not our philosophy. So we are proceeding without planning anything. We will get a "vision statement" about the project, but that's it in terms of scope.

I'm not sure I can entirely wash my hands of this, but I feel I made my attempt to intervene on the side of actually accomplishing anything worthwhile and was told no in no uncertain terms.
