What this video covers

Parkinson's law: work expands to fill the time given. Give it a week and it takes a week; give it an afternoon and it’s done by tea - often just as well.

Same email either way - but given all afternoon the work stretched to fill it, and given fifteen minutes it compressed to the essentials and still got done. The task never needed the extra time; it just expanded to use it. That's Parkinson's law - so a deadline is a design decision, not an afterthought.
