Definition
Scrum is a process framework used to manage product development and other knowledge work. Scrum is empirical in that it provides a means for teams to establish a hypothesis of how they think something works, try it out, reflect on the experience, and make the appropriate adjustments. That is, when the framework is used properly.
Scrum is structured in a way that allows teams to incorporate practices from other frameworks where they make sense for the team’s context. [Ref. 2]
