Can you explain what the Scrum methodology is and how it is used in project management?

Scrum is an agile project management methodology often used in software development. It is based on an iterative approach, where work is divided into short cycles — sprints (usually 2-4 weeks). Scrum has key roles: Product Owner, Scrum Master, and the development team.

Main elements of Scrum:

• Product Backlog — a list of requirements and tasks, prioritized.
• Sprint — a fixed period during which the team completes a set of backlog tasks.
• Daily Stand-ups — short meetings for team synchronization.
• Retrospective — an analysis of the past sprint to improve processes.

Scrum helps quickly adapt to changes, increases transparency and team engagement, and promotes regular delivery of a working product.
