Management that is external to the Scrum Team is not involved in the Daily Scrum because:

The Daily Scrum is an event for the Developers to inspect their progress towards the Sprint Goal and adapt their Sprint Backlog accordingly. It is not a status meeting or a reporting session for managers or other stakeholders.

The presence of external managers may hinder the self-organization, collaboration, and transparency of the Developers. It may also create pressure, interference, or distraction for the team.

The Scrum Master is responsible for ensuring that the Daily Scrum is held and that only the Developers participate. The Product Owner and other stakeholders may attend as observers, but only if the Developers find it useful.
