For example, project B is dependent on project A \(external soft dependency\). You want to make sure that project A is executed on time so that the schedule of project B is not affected. The **Dependencies** column shows that there is an outgoing external dependency from project A and an incoming external dependency to project B. You can then use the incoming dependency to determine whether a delay in project A will affect project B. ## Procedure 1. In the timeline view, select the show or hide columns in gantt icon \(\[Omitted image "show\_hide\_columns.png"\] Alt text: show or hide columns in gantt icon\). Add the **Dependencies** column if it is not visible. The number of incoming and outgoing external dependencies are displayed, if any. 2. Select the external dependency in **Dependencies** column for the project. 3. In the **Dependencies** pop-up dialog, click a tab to review the dependency: - **Inbound tab** Tasks that have an incoming dependency from a project are listed. - **Outbound tab** Tasks with an outgoing dependency to the project are listed. \[Omitted image "ReviewExternalDependencies.png"\] Alt text: Dependencies example 4.
