The daily standup is focused on ensuring the team stays synchronized on their commitments for the sprint, and it is meant to be a short meeting where team members quickly discuss what they did the previous day, what they plan to do today, and any blockers they are facing. It is not a forum for external stakeholders to ask detailed questions about the sprint backlog or delivery timelines, as this can disrupt the team's focus and hinder the meeting's efficiency.
By explaining that the standup is about synchronizing commitments, the project manager helps the business partners understand the purpose of the meeting and suggests an appropriate time and place for discussing more detailed or strategic topics.
