I have two different but reinforcing memories that support this. 1) I remember being in a Requirements Review meeting and spending an entire hour debating the meaning of a word. Don't remember the word, but it was something like "includes". 2) I separately remember being in a Requirements review for a feature that concluded successfully. Then later in a Design Review for that feature. And after that, Code and Unit Test reviews of the same feature. Then, months later, the feature was presented to the person who asked for it in the first place and then said, "that's not what I wanted. I wanted xxx instead." Yes, this person was at the Requirements and Design reviews!
