The Agile Software Development Model is an iterative and incremental approach to software development. The main idea is to build the product fast and ship often. The Agile model follows the Agile project management philosophies and methodologies for the completion of the software project. For example, the Scrum framework is one such Agile methodology.
The Scrum methodology is characterized by short timeboxed phases. Each timebox phase is called Sprint. Each sprint usually lasts for 2 – 4 weeks.
At the end of each sprint, a shippable product increment is completed, deployed, and shipped for the customer.
The Scrum Team consists of the Product Owner, Scrum Master, and collaborative cross-functional team members( Developers, Testers, and others).
The product backlog is the prioritized set of features that needs to be implemented for the project to be an ultimate success. The product backlog items are categorized into Epics, Features, User Stories, etc.
High-priority items are selected from the Product Backlog for each sprint in sprint planning sessions. The Sprint Backlog consists of the selected user stories, tasks, etc that need to be worked upon in the sprint.
