In a multiphase study conducted from 2000 to 2002, the authors examined the relationships between Internet-speed software development practices and agile and traditional development principles, and compared the two sets of principles. They found some overlap between traditional software development principles and agile principles but also some important differences?for example, traditional development stresses a formal, controlled environment whereas agile development promotes an informal, collaborative environment. Moreover, although some Internet-speed development practices seem similar to traditional software development practices, their configurations and deployment are more closely aligned to agile development principles.
