As mentioned before it is clearly necessary for more information to be given, but off the concept of the question it would matter more on the company. Larger companies would most likely be more concerned about the schedule variance as they most likely have a budget that could sustain additional cost. Smaller companies would most likely be more concerned about the cost variance. They are running on smaller funds and go over budget could sink a company before it even starts. Start ups do have to worry about meeting a schedule due to worry about market changes, but they most likely have smaller work forces and expect schedules to suffer a long a project. Obviously, these are all strong assumptions and would really depend more on the environment and ethics of the company.
