"so-and-so isn't coming today, so let's have stand-up now"
"hey, I'll just come over there and we'll do stand-up there"
It seems so easy and innocent to simply change the time and place of stand-ups, especially when key people such as the PO or Scrum master may not be attending the meeting for the day. The reasons I recommend for not changing are:
HabitThe need for good habits is possibly the most obvious reason for not changing the time and place of your daily stand-up. If the daily stand-up becomes a habit it will be ingrained into the psyche of your team and the operation of the stand-up becomes something that individual team members provide, rather than an action that is demanded of them. By making stand-up a habit, you have left them with extra creative juices to use in more mentally demanding tasks, like design or architecture.
There's a reason why Steve Jobs used to wear the same clothes everyday, it's because it was a habit he had developed. He did not need to use will power or creative juices to make a decision on what to wear, meaning he used these mental resources later on in the day for more important things.
