UNDERSTANDING CONSTRAINTS.
1. What are CONSTRAINTS?
They are the parameters you can assign to activities to control the behavior of bars as your project changes. Constraints in FastTrack Schedule are based on the CPM (Critical Path Method) project management model and follow the CPM standards
it will allow activities in your schedule to begin and end within an elastic window of time, until the activity’s start or finish comes into conflict with another dependency.
it will not allow activities in your schedule to begin and end before or after the date or time you have specified.
it will not allow activities in your schedule to begin or end on any date or time except those which you specified. A hard constraint effectively locks your bar finish or start and, if the bar is linked, bypasses the defined dependency if that dependency conflicts with its specified start or finish.
SOFT. The activity is scheduled to begin at the earliest possible moment, taking into account other scheduled activities. There is no specified Constraint Date, however the Project Start Date often acts as the Constraint Date. This is the default constraint type when bars are created by entering the Duration.
SOFT. The activity is scheduled to begin at the latest possible moment, taking into account other scheduled activities. There is no specified Constraint Date.
MODERATE. The activity is scheduled to begin no earlier than on the Constraint Date you specify. If necessary, it may begin later. This is the default constraint for new activities that are entered by drawing bars.
MODERATE. The activity is scheduled to begin no later than on the Constraint Date you specify. If necessary, it may begin earlier.
MODERATE. The activity is scheduled to end no earlier than on the Constraint Date you specify. If necessary, it may end later.
MODERATE. The activity is scheduled to end no later than on the Constraint Date you specify. If necessary, it may end earlier.
HARD. The activity will only begin on the specified Constraint Date.
HARD. The activity will only end on the specified Constraint Date.
