I used to work in banks where you had teams of architects create high level design (HLD) docs that get turned over to the design team to produce low level designs (LLD) that the get turned over to developers how are meant to write the code, then to be turned over to the testing team. With massive handover meetings at every stage and forests of paper for milestone documentation that had to be signed off.

Never had my soul be destroyed as completely and I seen such a massive waste of time and money.
