The basic principles are the basis of repeated development approaches such as Extreme Programming, Unified Process, and Rational Unified Process (RUP) and have been introduced in a number of books, but the guidelines apply, with specifics on how to actually run a project over there . Using the framework of the Unified Process (UP), Bittner and Spence present a simple approach, easy and convenient way to organize, estimate, staff, and managing an iterative project. Although this book is invaluable for the project following UP and RUP, the overall management framework presented is free to use various approaches, including Extreme Programming, Microsoft Solutions Framework or other development approaches iterative and incremental.
