AGILE SOFTWARE DEVELOPMENT METHODOLOGY

Agile software development is a group of software development methods in which requirements and solutions evolve through collaboration between self-organizing, cross-functional teams. It promotes adaptive planning, evolutionary development, early delivery, continuous improvement, and encourages rapid and flexible response to change

AGILE METHODS:

• Adaptive software development (ASD) is a software development process that grew out of rapid application development work by Jim High smith and Sam Bayer. It embodies the principle that continuous adaptation of the process to the work at hand is the normal state of affairs.

• Agile modeling (AM) is a methodology for modeling and documenting software systems based on best practices. It is a collection of values and principles that can be applied on an (agile) software development project. This methodology is more flexible than traditional modeling methods, making it a better fit in a fast changing environment.[1] It is part of the Agile software development tool kit.

• Agile Unified Process (AUP) is a simplified version of the Rational Unified Process (RUP) developed by Scott Ambler.[1] It describes a simple, easy to understand approach to developing business application software using agile techniques and concepts yet still remaining true to the RUP. The AUP applies agile techniques including test-driven development (TDD), Agile Modeling (AM), agile change management, and database refactoring to improve productivity. 

• Crystal Clear Methods Crystal Clear is a member of the Crystal family of methodologies as described by Alistair Cockburn and is considered an example of an agile or lightweight methodology.

• Kanban is a method for managing knowledge work with an emphasis on just-in-time delivery while not overloading the team members. In this approach, the process, from definition of a task to its delivery to the customer, is displayed for participants to see. Team members pull work from a queue.

• Scrum is an iterative and incremental agile software development methodology for managing product development. It defines "a flexible, holistic product development strategy where a development team works as a unit to reach a common goal", challenges assumptions of the "traditional, sequential approach" to product development, and enables teams to self-organize by encouraging physical co-location or close online collaboration of all team members, as well as daily face-to-face communication among all team members and disciplines in the project.
