Agile software development emphasizes four core values.

• Individual and team interactions over processes and tools
• Working software over comprehensive documentation
• Customer collaboration over contract negotiation
• Responding to change over following a plan

Agile model features include:

• The process is broken into individual models that designers work on
• The customer has early access to view the progress which enables them to make changes also early if needed
• Errors can be fixed in the middle of the project
• Encourages testers and developers to work together
• The planning phase is less and the development is executed in short (2-4) weeks iterations.

Benefits of Agile model development are:

• Transparency: It provides opportunities for clients to be involved throughout the project.
• Early and Predictable Delivery: By making fixed schedule sprints, new features are delivered quickly and frequently. This also provides the opportunity to release or beta test the software earlier than planned.
• Predictable cost and schedule: Because each sprint is of a fixed schedule, the cost is predictable and the amount of work for a team is fixed.
• Allows for change: There is always an opportunity to add or change backlogged items for the next iteration.
• Focus on users: By focusing features on the needs of the real users, each feature delivers value and is not just a component.
• Improved quality: Due to the breakdown of the project in multiple units, the team can focus on quality development, testing and collaboration.
