Chart 3.1 is a chart display in the Potential Improvements with all the input/output variables
along the side (Y axis), and the potential percentage improvement along the bottom (X axis). The
percentage improvement for each input and output that the DMU would need to make in order to
become efficient is shown in the form of graphical bars. Chart 4.1 showed the comparison
between Astro and Maxis. The table shows Maxis is bigger than Astro in term of size. Maxis is
operating at very high cost to generate the high net income. It is a good reference for Astro.
