Characteristics of Scrum Scrum is a reference model that defines a set of practices and roles, and can be taken as a starting point to define the development process to be implemented during a project. The main roles in Scrum are the ScrumMaster who maintains the processes and works similar to project manager, the ProductOwner, representing stakeholders (internal or external customers), and the Team which includes the developers. During each sprint, a period between 15 and 30 days (the magnitude is decided by the team), the team creates an increment of potentially deliverable software (usable). The set of features that go into each sprint is the Product Backlog, which is a set of prioritized high-level requirements that define the work to be done. The Product Backlog items that are part of the sprint is determined during the Sprint Planning meeting. During this meeting, the Product Owner identifies the elements of the Product Backlog that he wants completed and made known to the team.The team then determines how much of this they can commit to complete during the next sprint. During the sprint, no one can change the Sprint Backlog, which means that the requirements are frozen for sprint. Scrum enables the creation of self-organizing teams to drive the co-location of all team members, and verbal communication among all members and disciplines involved in the project. A key principle of Scrum is the recognition that customer during a project may change their minds about what they want and need (often called requirements churn), and the unpredictable challenges can not be easily faced in a predictive and planned. Therefore, Scrum adopts a pragmatic approach, accepting that the problem can not be fully understood or defined, focusing on maximizing the team’s ability to deliver quickly and respond to emerging requirements.There are several implementations of systems to manage the Scrum process, ranging from yellow notes “post-it” and slates to software packages. One of the biggest advantages of Scrum is that it is very easy to learn and requires very little effort to start using.
