The Dependency detail pane shows the details of a dependency as forecast and is available from the Gantt view, Work sheet and Gantt view, Product sheet.
The detail pane provides details about the dependency and the two activities or phases associated with it. Note that while the start and finish dates of the dependency are constrained by the start and finish dates of the parent activities or phases the dependency does not have to start when one starts of finish only when the other finishes. The difference in dates can give insight into the behavior of the project: is a team waiting on another team and therefore not communicating until the start date of the dependency?
The detail area provides the dependency start and finish and duration as well as other details as shown. The detail area also defines the start and finish objects (phase or activity) and some basic information about each object.
The Timeline button displays a separate chart of activity with respect to time. The Dependency button displays a separate chart showing the two involved activities' or phases' progress with respect to time. See the Dependency Timelines article for details.
