In project management, a baseline is the project's original plan. On the above project plan, the baseline plan is highlighted (yellow) so that it is easily distinguishable from the current plan. Some Gantt chart software and project management software offer the feature of highlighting the baseline plan. Some project management software will let the user lock the baseline plan so that the baseline plan does not change when the schedule is edited. 

All Schedules on this web site were created using Milestones software. This includes Milestones Professional, which is a powerful, fast, and easy to use project scheduler, and Milestones Simplicity, a basic program for creating Gantt charts. These programs can both be used to present schedules. They are both great examples of project planning software.
