Abstract: In this paper, we present a model to evaluate both marketable quality and profitability of corporations. We apply the real values of some leading Japanese manufacturing corporations to our proposed model to analyse its accuracy. By analysis we found that the theoretical and real standard values of the marketable quality indicator for the rate of operation at the break even point were both 0.6 (that is 60%). We validate the proposed model and show that the proposed model gives a good approximation of the economical trends of Japanese corporations. We also discuss how to increase the relative annual profit by increasing marketable quality.

Keywords: business systems; business modelling; marketable quality; profitability models; break even point; Japan; Japanese manufacturing.
