What is Agile Scrum Methodology?
This methodology uses the iterative and incremental approach towards software development. It was invented in 1993 by Jeff Sutherland, John Scumniotales, and Jeff McKenna. Scrum actually has a skeleton which contains a set of practices and predefined roles. There are three main roles in it, namely, the 'Scrum Master', 'Product Owner', and the 'Team'.
