# Review external dependencies between projects

Review the external dependencies between projects in a portfolio to track projects that are dependant on each other more closely.

## Before you begin

Role required: it\_portfolio\_manager

Open demands and projects in the timeline view of the Portfolio Planning Workbench.

## About this task

As a portfolio manager, you may want to know the projects which are dependent on each other so that these projects can be tracked more closely.

For example, project B is dependent on project A \(external soft dependency\) and 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 the use the incoming dependency to determine whether a delay in project A will affect project B.

## Procedure

1.  Click the show or hide columns in gantt icon \(\[Omitted image "show\_hide\_columns.png"\] Alt text: show or hide columns in gantt\) in the timeline view and add the **Dependencies** column if it is not visible.

    The number of incoming and outgoing external dependencies are displayed, if any.

2.  Click 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.
