Create a project baseline

A baseline is a collection of all planned dates for all tasks and milestones at the time you create the baseline. If the project is not on schedule, create a baseline to get an idea of how much schedule slippage has already occurred.

About this task

The baseline appears as a set of gray lines offset to the left or right of the bars that represent the actual tasks on the Gantt chart. These baselines represent planned dates, while the task bars represent the actual dates. If the project tasks are shifted to the right of the baselines, a project is running behind schedule. Create a baseline any time you want the most up-to-date view of deviations between actual and planned values. You can create as many baselines as necessary throughout the project.
Note: Nested projects cannot have baselines. Baselines are allowed for top-level projects only.


  1. Open the planning console.
  2. Click the Gantt chart icon ().
  3. Click Create Baseline. A dialog box appears.
  4. Enter a name and a description.
  5. Click OK.
  6. Then open the project baseline by clicking the Gantt chart icon () again and selecting the baseline from the choice list.
