Requirements Experience in Practice: Studies of Six Companies

To understand how to apply different requirements engineering practices and where difficulties may arise when implementing a set of requirements engineering practices, it is often useful to consider how others have done and the troubles they have encountered. This chapter describes six industry cases of applied requirements engineering, with a focus on areas where further improvements are desired by or recommended to the companies. Many of these improvement areas are also identified by other, independent, requirements engineering state of practice surveys, and thus indicate areas that warrant special attention when constructing a requirements engineering process for an organization.
