Scrum is an agile framework that manages time through scheduled meetings like the daily scrum, sprint planning, sprint review, and retrospective. These meetings are planned in advance and kept brief, with daily scrums being 15 minutes and other meetings usually 1-2 hours. Additional "tactical" meetings support the sprint like grooming and estimation, while "strategic" meetings involve stakeholders for estimation and release planning. Overall, scrum meetings are designed to take only 15% of the allocated sprint time to minimize interruptions and keep teams focused on autonomous work.
