The Project Schedule show the a deal's timeline with its phases and milestones.

On the left side of the Project Schedule page you will see the deal's events. Events are either phases or milestones. A phase is generally made up of several milestones. The list you see is a list of phases and milestones in chronological order. These phases and milestones also appear on a calendar to the right. These phases can be collapsed to hide the milestones from view. This is done by clicking on the down arrow to the left of the phase name.
The calendar moves left to right and, by default, shows only months and years. Using the Zoom button in the top right corner, you can choose to break the calendar down to months, weeks, and days.
The Project Schedule also allows members to comment on phases and milestones. This is done by clicking on the message box to the left of a phase or milestone name.
The Add Event button can be used to add a new phase or milestone.
