Apart from Apple Division and Orange Division, Computer Company has another division, namely Division C. The Chief Executive Officer of Computer Company asks you to analyze the performance measurement system of Division C, and the relevant information is listed below. Division C evaluates its managers based on return on investment (ROI). Katy Fung and Susan Wong, managers of the product lines P and Q respectively, have recently suffered from declining profits in their product lines. Over dinner, they discuss the problem, and how they could improve performance. Most of the discussion centers around ways to increase sales. Near the end of the dinner period, however, Susan Wong wonders whether there is some way to reduce investment, and by decreasing the denominator of the ROI fraction, to improve the final result. Back at work, Katy Fung continues to mull over Susan's remarks. She decides to pursue the matter further, and before the end of the quarter she has sold quite a bit of older equipment and replaced it with equipment obtained with a short- term lease. Her performance, measured by ROI, is markedly improved, although sales continue to be disappointing. Who are the stakeholders in this situation? Is Katy's action ethical?
