Detail View 
Use the Detail View to review the milestones and sub-milestones for the selected initiative. The Detail View allows you to view milestones and sub-milestones as either a Milestone Summary or as a Fishbone Diagram.
Milestones are tasks that support an initiative. They are the individual work items that must be executed in order to complete an initiative. You can assign any number of milestones to an initiative. If a milestone is complex, it may have sub-milestones that break out the milestone into separate sub-tasks.
Prerequisites
You have Create Initiatives permissions granted by your administrator and you have access to the Add Milestone or Sub-Milestone button in the Initiative Summary to create initiatives and edit and delete initiatives you created. With these permissions, you can also edit and delete initiatives that you own that were created by someone else.
You are the milestone or sub-milestone author or owner if you want to edit or delete your own milestones and sub-milestones. If you do not have the correct permissions, selecting the milestone or sub-milestone will display information about it instead.
Features
You can do the following in the Detail View:
You can control whether the Milestone Summary or Fishbone Diagram appear as the default view by setting a preference.
You can develop milestones or sub-milestones and maintain the ones you created if you have the Create Initiatives permission.
You can review milestones and sub-milestones for an initiative.
