An introduction to agile methods

Agile Methods are creating a buzz in the software development community, drawing their fair share of advocates and opponents. While some people consider agile methods the best thing that has happened to software development in recent years, other people view them as a backlash to software engineering and compare them to hacking. The aim of this chapter is to introduce the reader to agile methods allowing him/her to judge whether or not agile methods could be useful in modern software development. The chapter discusses the history behind agile methods as well as the agile manifesto, a statement from the leaders of the agile movement. It looks at what it means to be agile, discusses the role of management, describes and compares some of the more popular agile methods, provides a guide for deciding where an agile approach is applicable, and lists common criticisms. It summarizes empirical studies, anecdotal reports, and lessons learned from applying agile methods and concludes with an analysis of various agile methods. The target audiences for this chapter include practitioners, who will be interested in the discussion of the different methods and their applications, researchers who may want to focus on the empirical studies and lessons learned, and educators looking to teach and learn more about agile methods.
