Add tasks and projects to the timeline
After you have created projects and added tasks to your project, you can include projects and/or tasks that have start or finish dates on the timeline at the top of the Project Center, and at the top of the Schedule page for your project.
Adding tasks to the timeline on the Schedule page
The Schedule page is the page that lists all of a project’s tasks when the project is opened for viewing or editing. The timeline at the top of the Schedule page is only viewable when the project is open, so it is a good tool for illustrating tasks at the individual project level.
To add tasks to the timeline on the Schedule page, first open the project for editing. Next, select the task rows that you want to include in the timeline, and then click Add to Timeline in the Tasks group on the Task tab.
If a task has a start date and a finish date, it appears on the timeline as a bar that spans those dates. If a task has only a start date or only a finish date, it appears as a single point on the timeline, marked with a diamond.
After adding tasks to the timeline, there are several things you can do to change the way the timeline appears. For more information, see Change the appearance of the timeline.
Adding projects and tasks to the Project Center timeline
The timeline at the top of the Project Center provides a succinct way to purposefully illustrate all of the projects and major tasks going on in your organization. You can use this timeline to craft a visual executive summary of your portfolio of projects.
To add a project to the Project Center timeline, select the project row, and then, on the Projects tab, in the Timeline group, click Add Project.
You can also add tasks to the Project Center timeline, although a best practice is to only add major tasks that you want to have increased visibility. The Project Center timeline is intended to be used to illustrate all projects in your organization, and as such, it can get easily cluttered if too many tasks are added. To add a task to the Project Center timeline, select the row for the project that contains the task you want to add, and then, on the Projects tab, in the Timeline group, click Add Tasks. The Select Tasks for Timeline box appears. By default, only the first outline level is displayed, but you can expand the summary tasks on the Select Tasks for Timeline box to drill down to the subtask level(s). Select the task row(s) that you want to add to the Project Center timeline, and then click OK.
