After you make important additions or changes to your project plan, it’s a good idea to save the plan.
To save your project
.
The first time you save your project, the PlanningWizard dialog box appears. The Planning Wizard continuously monitors your actions as you work. It helps you complete tasks and makes suggestions on any shortcuts you want to use. The question in the dialog box asks if you want to save a baseline plan, which is a copy of your original plan data against which you can compare actual data. For more information about baseline plans, see Chapter 17, "Setting the Baseline."
By default the PlanningWizard is turned on. You can turn it off, or if you’re not sure whether it’s on, you can check its status.
