  6. Anxious for Awareness Brad asked Sally to add a feature to her product… three weeks ago! ICSE NIER 2009

  7. To track another team’s progress… • Befriend your bugs and work items. • Subscribe to activity newsfeeds. • Find out what the team is doing when they’re not working on your stuff. • Feel empathy for an overworked team, but mitigate your risk and find a workaround. ICSE NIER 2009

  8. To discover who is using your stuff… • Compute the social call graph: • Find who wrote the code that calls your code. • Find who wrote the code that your code calls. • Learn who cloned your code, and keep them up to date on changes to the original. • Discover how difficult your code is to use. Write better documentation to cover how it is actually being used. ICSE NIER 2009

  9. Status and Research Questions • Building Codebook prototype on Visual Studio Team System • How should we present activity data about developers without causing them to alter their behavior in order to appear more productive? • How should we aggregate and abstract activity data across groups of people and artifacts?
