Methodologies in the IT world means detailed, stringent, defined principles and mandatory processes and predefined ALGORITHMS. Every process or STEP should be carefully followed in sequence and documented properly.

Scrum is always MISUNDERSTOOD as a methodology rather it is a set of instructions given mainly for the product which has high uncertainties, complexities and unpredictable.

It is a process which works best for all the players emerges from the use of scrum and the boundaries are set by Scrum.

Scrum as a FRAMEWORK describes roles and rules upon principles that help and facilitate people in a low-prescriptive way.

The Scrum framework leaves different options and tactics to play the game as it replaces the defined algorithmic approach with respect to people and self-organization to deal with unpredictability and uncertainties issues. The Scrum core values give DIRECTION to the actions and the behavior of the Scrum team, and the additions they make to the framework.
