The application size exponent is aggregated of five scale factors (SF) that describe relative economies or diseconomies of scale that are encountered for software projects of dissimilar magnitude. A project exhibits economies of scale if the exponent is less than one i.e. effort is non-linearly reduced. Economies and diseconomies of scale are in balance should the exponent hold a value of one. A project exhibits diseconomies of scale if the exponent is more than one i.e. effort is non-linearly increased.
