Besides the Summary section displayed in the previous section, the Daily Project Details analysis also provides a set of "Drill Downs", which provide more detailed information gathered from analysis of the raw sensor received by all members of the given project for the given day. In this case, we can see a breakdown of the Active Time by User and the top-level workspace (a workspace can be thought of as a canonicalized directory), the build invocation and results by configuration, and the test coverage by top-level workspace.
These drill downs are particularly useful in development when attempting to diagnose a sudden change in the summary values from this same analysis. For example, if coverage has been at 100% and suddenly drops to 80%, what top-level workspace in the system was responsible? The drill down for coverage should indicate which top-level workspace dropped in coverage, and then the drill down for commit data will reveal which developers were committing files in that region of the system.
