In this paper, we present NavTracks, a tool that supports browsing through software. NavTracks keeps track of the navigation history of software developers, forming associations between related files. These associations are then used as the basis for recommending potentially related files as a developer navigates the software system. We present the reasoning behind NavTracks, its basic algorithm, a case study, and propose some future work.

At its core, software development is an information-intensive knowledge generation and consumption activity. Information about markets and trends are analyzed to create requirements that describe what a desired software system needs to do. Those requirements become information for software developers to use to produce models and code that, when executed, provide the behavior desired for the system. The execution of a system creates more information that can be analyzed as to how the software performs, and so on. We are interested in how software tools can enable the productive development of software. Our hypothesis has been that software development productivity can be increased by improving the access and flow of information between the humans and tools involved in creating software systems. In this chapter, we review an evolution of technologies that we have introduced based on this hypothesis. These technologies are in use by large software development organizations and have been shown to improve
