What is XP

Rapidly increasing of requirements of business pushed researchers to define new approaches and methodologies to meet marketing needs. Agile methodology has been created and replaced the traditional-driven development methods that focus on soliciting, documenting a complete set of requirements, and take a long time comparing to market change. On the other hand, customers need to be closer to the development process and collaborate with team development. Despite agile advantages, introducing new tools, coordination, and collaboration concepts, some challenges still need to be discussed and improved. These challenges relate to achieve balanced IT service development process in the organization. As a result, new trends have been created to facilitate new changes in software development. This chapter will study agile methodologies and different challenges with suggested solutions generated from agile philosophy itself.
