Scrum – is the methodology of project management, which is actively applied when developing the information systems for a flexible software development.

Main Ideas:

1. People and interaction are much important than processes and tools.
2. The running product is much important than a comprehensive documentation.
3. Cooperation with a customer is much important than a contract negotiation.
4. Being ready for changes is much important than a ground-plan following.

All the development consists of sprints. Sprint – is an iteration during which a new functional is created. Sprint’s duration is about from 2 till 4 weeks. Usually, a sprint duration is established due to a trial-and-error approach, depending on the number of teams, project specification, etc. The shorter the sprint is, the faster a new functionality is introduced, the faster feedback is coming. Throughout the sprint, no one can change the sprint requirements from a backlog.

Best software testing companies provide some more important definitions for the better understanding of the topic under discussion. Among them:

• Backlog – is the list of the project requirements, which is arranged by priority. Any member of a quality assurance team or software specialist can edit the backlog.
• Sprint Story – is the backlog functionality, chosen by a project owner from a project backlog.
• Burndown Chart – is a chart, which should be frequently updated and show what tasks have been already done and which one needs to be done.

Scrum methodology in the production process identifies certain roles: core roles and ancillary roles.

Core Roles:

• Scrum Master – is a manager who performs various scrum meetings, supervises all the scrum principles, conducts a scrum process correctly.
• Product Owner – a customer, who represents the interests of the end-users and other stakeholders.
• Scrum Team – developers and testers who are responsible for the results. The team consists of 3-9 people.

Ancillary Roles: experts, users, managers, stakeholders and sometimes quality control consultants.
