I have never seen that in action. The seniors don't care, don't read the status updates, are not listening to actual stand-ups. We just pretend to. When something needs to be communicated or worked out with team members efficiently it's with the relevant people directly.

Stand-ups are a waste of time.

Why precisely?

Maybe for very new people who need high levels of guidance it could be helpful. But it’s a practice that has no basis in evidence to be so widespread.
