To use baselines in Project

Project baselines refer to the scheduled start and end dates of each activity and milestone in an activity structure at a certain date. You can enter dates through:

  • The external scheduling package.
  • The Create/Update Baseline (tppss2220m000) session.
  • The Activity Baseline (tppss2120m000) session.
  • The Milestone Baseline (tppss2121m000) session.
Use a baseline for...

A baseline is a snapshot of the scheduled time line of activities. It can be used to time-phase a top down budget version in the Generate Time Phased Budget (tpptc5200m000) session. The time-phased budget is calculated by using the budget version and the baseline (taking into account the earned value method, and the scheduled dates of the activities).

A baseline is used for performance measurement. If you want to generate performance measurement, the baseline must be Approved and also the budget version must be Actual. Amounts of the scheduled activities that can be released depends on where the activity on the baseline is positioned in the performance measured periods.

Example

Activity A has a distributed amount of a 10,000 euros with the Start and End Percentage earned value method. 10% is released when starting the activity, 90% is released at finishing it. The baseline is approved and falls into three periods. In the first period A starts, therefore an amount of 1000 euros is released for that period. In the second period work is still performed on A and so none is released, and in the third period when A is finished, an amount of 9000 euros is released. To release the budget amount LN looks at the baseline data and the EVM.

Creating a baseline

The baseline data depends on the start and end dates of the activity structure or milestones used in a project. In Requirements Planning you can indirectly create or update a baseline using one of these sessions:

  • Milestone Baseline (tppss2121m000)
  • Activity Baseline (tppss2120m000)
Note

If you did not enter a baseline, LN takes the planning dates of the activities.

From each of these sessions you can start the Create/Update Baseline (tppss2220m000) session where you can create or update a baseline that is based on the underlying activity structure of this specific project.

The Baselines (tppss0520m000) session provides an overview and enables you to change the baseline status.
