A principal component analysis of physical efficiency criteria such as calving and lambing percentages is studied for 91 farmers in a homogeneous farming area. The first component implied that a farmer achieving a high score in one efficiency criterion, also achieves high scores in other criteria. This component, called a ‘performance index’, showed a common association with financial success in farming. This ‘performance’ factor can be included in the routine computer printouts of farm records and could furnish additional information concerning management at no extra cost.
