A restriction that is set on the start or finish date of a task. If you enter a new task by specifying parameters (task name, duration, etc.) rather than start and finish dates, RiskyProject does set a constraint and the task will start and finish as soon as possible. If you specify a start date, a constraint is set to Start No Later Than. If you specify a finish date, a constraint is set to Must Finish On. You can change or remove constraints in the General tab of the Task Information dialog box. Constraints for start or finish dates are indicated using an orange background in all views.
