The Project Management Institute, however, endorses the accepted convention that a negative variance is a bad thing, and a positive variance a good thing. A variance is the difference between the projected budget and the actual performance for a particular account. A negative variance means that the budgeted amount was greater than the actual amount spent. A positive variance means that the budgeted amount was less than the actual amount spent. Note there is some debate over whether a negative variance means an underrun or an overrun.
Three types of ulnar variances exist, according to Dr. Philip Blazar. A normal or neutral ulnar variance means the surface of your distal ulna and radius are equal. A negative variance occurs when the ulna is shorter than the radius. These two variances respond well to conservative treatments, such as exercise. A positive ulnar variance describes an ulna longer than the radius. Severe stages of positive variance conditions may require wrist arthroscopy to repair tears and ligament injuries. All variance types require flexibility and strengthening exercises to return your hand and wrist to a normal functioning level.
