Well, they might be. But not always.

In an era of activity based working and off-shoring, it’s
increasingly rare that the basic scrum model is adhered to.
The daily stand-up (Team Scrum, Scrum of Scrums) is the one
daily opportunity on our projects when you know everyone is going to be there
just in case you need to have a conversation straight after.
It’s not
about you. It’s about the people that might need your help.
Otherwise we resort to email. And we all hate email.
