You use this measurement technique if particular targets or events (called milestones) are defined.

The milestone technique is typically used in:

• Development work
• Design and engineering
• Production and assembly
• Cases where the ordering party prescribes milestones - for example, as the basis for payments

The milestone technique is date-related and is preferred on projects which last longer than three months.

You must maintain milestones relevant to progress analysis in the project. You maintain planned dates in the WBS, network, project planning board, or structure planning.

You must maintain the following data in the milestone detail screen for the system to take account of the milestone in progress analysis:

• If the milestone is maintained for a WBS element, the following must apply in the Change Project: Milestone Overview screen:

• Set the indicator EV for progress analysis

• A POC in percent

• If the milestone is maintained for a network activity, the following applies in the detail screen for the respective milestone:

• Set the indicator for progress analysis

• A POC in percent

Each milestone represents a portion of the work completed or the work to be completed in an activity or WBS element. You can enter milestones for WBS elements and activities.

In the case of the planned POC; the system takes account of the following milestones:

• Schedule dates for milestones in the activity/activity element.

• Fixed date (basic or forecast date) for milestones in the WBS element

For the actual POC, the system takes account of the actual milestone dates. You maintain actual dates manually when the milestone is reached, or the system takes them from the completion confirmation.

If you set the automatic milestone indicator in the completion confirmation, the system automatically adopts the actual dates from the confirmation as the actual milestone dates. Otherwise, when you save, the system asks for confirmation when you save the confirmation to the milestone dates.

The system determines the POC as follows:

• If the basic or forecast date for the milestone is reached, the planned POC for the activity or WBS element is updated to reflect the POC defined in the milestone.
• When the actual date for the milestone is reached, the actual POC is updated to reflect the POC defined in the milestone. The actual date for the milestone may be reached, for example, when an activity is confirmed.

You have maintained the following milestones for an activity:

The system determines the POC as follows:
