Project Dustbowl has required quite a bit of documentation review both in the pre- and post-acquisition process. Part of my job for Dustbowl, after being effectively removed from the personnel review team, was to go through much of the miscellaneous documentation that wasn't deemed important or was discarded as irrelevant during the initial due diligence and distill these down to a summary for the transformation team. Often you find interesting things in these "miscellaneous" sections after an acquisition. Other times it gives you a picture of how dysfunctional the organization really is. (This would imply, of course, that these documents should not have been discarded by the due diligence team in the first place, as evidence of dysfunction should bear on price, but that's another story).
Project Dustbowl's miscellaneous section contained this document (that I have redacted but is otherwise totally original):
