Changes in source code can both be managed and unorganized. We use heatmaps (colored contingency tables) to visualize patterns in source code changes.
Based on the changes in the source code we were able to visualize the co-dependencies of changes and thus reason about which components can depend on one another.
Dashboards for monitoring progress, quality or product performance we build dashboards. In our project in Software Center we have studied how dashboards at different companies are used.
