Scrum is a lightweight framework that helps people, teams and organizations generate value through adaptive solutions for complex problems.
Why people think Scrum works
Daily standups provide clarity of direction and accountability for engineers
Why Scrum actually works
Daily standups take care of everything that needs to be discussed quickly and efficiently so people who do actual work can get things done without interruption
