Scrum is a widely used agile project management method. The basic idea of scrum is not to plan a project rigidly, but to implement it step by step in so-called sprints. This approach has the advantage that short-term changes and issues can be addressed immediately. There are only a few rules, which are limited to three artifacts, three central roles and five activities.
For Scrum's 25th birthday in 2020, the method's creators Ken Schwaber and Jeff Sutherland have updated the Scrum Guide. Check out the bonus chapter of our popular whitepaper "Scrum Basics Explained" to learn what's changed.
