A comparison of issues and advantages in agile and incremental development between state of the art and an industrial case

Recent empirical studies have been conducted identifying a number of issues and advantages of incremental and agile methods. However, the majority of studies focused on one model (Extreme Programming) and small projects. To draw more general conclusions we conduct a case study in large-scale development identifying issues and advantages, and compare the results with previous empirical studies on the topic. The principle results are that (1) the case study and literature agree on the benefits while new issues arise when using agile in large-scale and (2) an empirical research framework is needed to make agile studies comparable.
