Scrum Methodology

The scrum process has 3 main phases.
Planning
In this phase, the project is planned and high-level design decisions are made.

Sprint Cycle (a common terminology)
The product is developed in a series of 1-to-4-week iterations, or sprints. Before a sprint is begun, a Sprint Planning Meeting is held to determine what features are to be implemented in that sprint. The sprint has 4 major steps:

• Develop the product further - implement, test, and document.
• Wrap up the work - get it ready to be evaluated and integrated.
• Review the work done in this sprint.
• Adjust for any changes in requirements or plans.

Release or Close
In this phase, the product's development is brought to a close, and the product is released.
