Describe working in IT to normies.

Thatโs perfect. Iโve had this happen numerous times in my career:
User/Manager: When will [major project] be completed?
Me: This is the first Iโve heard of this project. When was it scoped and what is the goal of the project? Who is running it?
User/Manager: Oh, I thought you knew. [Major Project] is due in a week. Your team should get rolling to meet the deadline!
Me: Looks like about six months of work even if we bust ass. Not gonna happen.
User/Manager: Why is IT always so useless?!?!?!
