Constraints tab - Check Schedule dialog box
Use the Check Schedule dialog box, Constraints tab to specify the settings to use for analyzing constraints applied to activities in the schedule.
Hard Constraints - Constraints that prevent activities being moved: Mark to analyze the percentage of activities that have constraints applied that will prevent the activity dates being recalculated according to the schedule logic. Hard constraints are Mandatory Start, Start On, Mandatory Finish, and Finish On. Completed activities, WBS Summary activities, Level of Effort activities, and start constraints applied to started activities are not included in this analysis. Specify the target for the acceptable percentage of activities that can have hard constraints.
Soft Constraints - Constraints that do not prevent activities being moved: Mark to analyze the percentage of activities that have constraints applied that will not prevent the activity dates being recalculated according to the schedule logic. Soft constraints are Start On or Before, Start On or After, Finish On or Before, Finish On or After, and As Late As Possible. Completed activities, WBS Summary activities, Level of Effort activities, and start constraints on started activities are not included in this analysis. Specify the target for the acceptable percentage of activities that can have a soft constraint applied.
