In my opinion, Schedule variance should be positive and cost variance negative is better if one situation has to be choose between two given. When schedule variance is positive, it is beneficial for the project because the project is progressing ahead of its schedule. While the schedule variance negative means the project is behind is a schedule which isn’t terrible however, it determines that the project worth is decreasing as its lagging behind the schedule. It can also determine that the project isn’t worth as much as it should be. When cost variance is negative, it does bring the project over budget but it can be worth more if it is completed on schedule.
