Same process run by different group will feel different.
Which means, given a 8 hours working day, that you've been needing the help of Dave since the previous day, for an average of 4 hours, and you didn't ask him yet?
It's very possible the guy thought he could figure it out, but discovered he was wrong and mentioned it in the stand-up because it was the first opportunity that day to bring it up (remember, in a lot of places stand-up happens fairly early in the morning in order to give coders the largest block of contiguous time for development).
Exactly. Which means that he's saying that at the standup not because of any special advantage given by it, but just because it's the very first appointment of the day. Had there been no standup, he would have asked for help anyway.
So either: 1) the standup covers up a fundamental malfunctioning of the team, namely that people can't communicate freely during the day, or 2) useful stuff that people say at the standup is stuff they would have said anyway at that time of the day.
