Each iteration is a mini project in itself. Each iteration is tested to ensure the quality of the software is maintained. Customer interaction is the backbone of the agile methodology. The agile model follows some principles and they are as follows: -• Individuals and interactions: Team members must be encouraged to take an active part in development and planning activities. They have the power to take actions on their own. Team members need to share their ideas to develop the product as a whole unit. • Working software: The goal here is to develop and provide a demo product to customers to understand their needs until the entire product is developed. • Collaboration with the client: Since the requirements may not be available at the beginning of the project, continuous interaction with the client is very important to obtain the right requirements. A lot of time is saved through collaboration with the client, as projects progress successfully. • Respond to change: Agile focuses on rapid responses to change and continuous development. Changes can be made at any time while features are displayed
