Baselines
Baselines allow you to compare the current positions of tasks, groups, and milestones in the timeline to any of the following:
the way they looked in the past
another saved schedule
an original schedule
Using Baselines, you can track schedule changes over time, compare two schedules for the same project, and more.
The dotted lines represent the baseline locations, while the full-color tasks are their positions today. In this example, the top set of tasks is behind the baseline schedule, the middle set is ahead, and the bottom set is consistent with the baseline.
Types of Baselines
Gantt baselines - create a baseline using the current location of tasks.
Jira-based baselines - create a baseline using data from Jira or a formula.
