Guide on Scrum for PSM I - Scrum Extreme Programming Exam Preparation

Definition: Scrum is an agile framework for managing a process. It's typically used in software development, but can be applied to any team-based project. Scrum allows for rapid iterations and constant feedback, helping teams to continuously improve and adapt.
Importance: Scrum is important because it provides a method for teams to work together and get things done more quickly. Through high communication and interaction levels, Scrum increases product quality, reduces time to market, improves stakeholder satisfaction, and enhances team morale.
How It Works: Scrum operates in iterations (called 'Sprints'), generally lasting two weeks to a month. The product owner creates a prioritized wish-list (Product Backlog). During Sprint Planning, the team pulls a small chunk from the top of this list (basically, enough for a short time period you're estimating for), then decides how to carry out those pieces. After the work done in a Sprint is reviewed (Sprint Review), the Scrum Master encourages the team to improve (during the Sprint Retrospective).
