Abstract. We present how a combination of static source code analysis, repository analysis, and visualization techniques has been used to effectively get and communicate insight in the development and project management problems of a large industrial code base. This study is an example of how visual analytics can be effectively applied to answer maintenance questions in the software industry. 1

Most software visualization systems and tools are designed from a single-user perspective and are bound to the desktop, IDEs, and the web. These design decisions do not allow users to collaboratively analyse software or easily interact and navigate software visualizations. We are building collaborative, interactive, multi-touch software visualization applications for multi-touch tables. Our user studies will outline the strengths and weaknesses of designing multi-touch software visualization applications and inform how users collaboratively conduct visual software analytics with multi-touch table user interfaces.
