The daily stand-up timebox should not exceed how many minutes?

The daily stand-up is a key event in SAFe that helps teams synchronize their work, identify impediments, and adjust their plans. It is a time-boxed event that should not exceed 15 minutes, as longer meetings can reduce the team’s focus and productivity. The daily stand-up is also aligned with the Lean-Agile principle of applying cadence and synchronizing with cross-domain planning, which enables teams to operate reliably and efficiently.
