Agile is not compatible with deadlines

Change my mind.

Discovering complexity of the thing you set out to implement on minimal, happy-path only requirements when everything is already tight and on fire just is not tenable. It's a cavalcade of shitty compromises and corner-cutting at it's finest. Backlog inflation is real folks. We keep the pretense that our ticket economy is strong, but the backlog depth doesn't lie... If I were to be allowed to use shitty central banking analogy.
