Few anecdotes from Amazon's folklore. "Why a six-pager has 6 pages?" A typical meeting at Amazon is 1 hour long -- 30 minutes reading followed by 30 minutes discussion. It is rumored that it takes Jeff Bezos 5 minutes to read and fully understand 1 page (10pt font, 1.2 line spacing). Hence 6 pages in 30 minutes. BTW, a six-pager can have an unlimited number of appendixes that do not count to the 6 pages limit. These appendixes provide extra in-depth info and often discussed during a meeting. But appendixes are not required reading. That said, quick readers oftentimes cover extra 10 pages during the silent portion of the meeting.
