Yep and here we are in 2024 and just this last week I got into a heated discussion with an 'Technical' Program Manager raging about how the deliverables are slipping by three days mostly because he and his up chain are heavily invested in a schedule that is built on hope. Not only are the estimates bad, but the resourcing from the different silos has not happened either, so there is tons of unfinished work just on the work that is known, let alone the unknown unknowns!

Next up he's about to find out his integration timeline is complete and utter bullshit.
