Scrum

Scrum is a lightweight framework that helps teams work together more effectively, solve complex problems, and deliver valuable products one step at a time.
It is based on empirical process control, meaning work is guided by transparency, inspection, and adaptation. Scrum encourages learning through doing, frequent reflection, and adapting plans as new insights emerge.
Scrum defines a Scrum Team, three artifacts, and five events, all supported by five core values. Each part of Scrum offers structure---but the real magic happens when teams use it to continuously learn, improve, and deliver value.
Scrum is easy to understand but takes practice to master. It grows with you as your team and challenges evolve.
You can find the full, official definition of Scrum in the Scrum Guide the foundation for anyone who wants to truly embrace and apply Scrum.
