What does Scrum mean?

In software development, Scrum is a lightweight framework for developing, delivering, and sustaining complex products. Scrum is a framework, not a methodology. It provides a structure for teams to work within, but does not prescribe specific practices. Scrum teams are self-organizing, with no imposed hierarchy. The key roles are the Product Owner, Scrum Master, and Developers. The core idea behind Scrum is to break down complex projects into smaller, manageable "sprints" of work with frequent feedback and adaptation.
