Scrum is a framework for managing projects that uses sprints, daily stand-up meetings, and artifacts like a product backlog to facilitate collaboration and ensure work is progressing towards goals. Key roles include the product owner who prioritizes work, the scrum team who does the work, and a scrum master who facilitates the process. Each sprint is time-boxed, usually to two weeks, and results in a potentially shippable product increment that is reviewed at the end of the sprint. Meetings like planning and retrospectives help coordinate work and improve the process. The goals of scrum include accountability, ability to adapt to change, and focus on delivering value.
