To use baselines in ProjectProject baselines refer to the scheduled start and end dates of each activity and milestone in an activity structure at a certain date. The situation at a certain date can be saved for future reference. Using a baseline you can evaluate the accuracy of the planning by comparing the scheduled dates saved in a baseline to the actual dates. Over time multiple baselines can be created. You can enter dates through:
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 two periods. In the first period A starts, therefore an amount of 1000 euros is released for that period. In the second 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 earned value method. Creating a baseline The baseline data depends on the start and end dates of the activity structure or milestones used in a project. In Planning, you can update a baseline using one of these sessions:
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 of all the baselines of a project and enables you to change the baseline status.
