le for the payingbills activity indicates an overall improvement in activity efficiency (all partial ratios improved). Since this is a valueadded activity, this means that activity performance has improved. The movingmaterials activity indicates a drop in activity productivity. Less output and less inputs were used to perform the activity. This is a nonvalueadded positive effect. The productivity ratios fail to reveal this, though—unless it can be shown that reduction of nonvalueadded activities always leads to a decline in productivity ratios (which seems unlikely). Thus, changes in profiles for nonvalueadded activities are difficult to interpret. The best way to deal with nonvalueadded activities is to include them as part of the productivity analysis of the process to which they belong. 2.

Sum of the two ponents: Resource efficiency ponent: ...............................................Purchasing $ 200,000 ..................................................Receiving 232,000 ...............................................Paying bills 4,530,000 $ 4,962,000 ...................... Activity output efficiency 0 Total process productivity change .......... $ 4,962,000 The sum of the two ponents gives the change in profits attributable to changes in process productivity. This shows that even though the procurement output’s demands for the output of the three activities remains unchanged, significant improvements in activity resource efficiency have increased the overall efficiency of the procurement process. Notice that the biggest increase came from the paying bills subprocess. This can be explained in large part by the elimination of the nonvalueadded activity of resolving discrepancies. 359 15–10 1. Productivity profile: Current system: Materials: 50,000/200,000 = Labor: 50,000/100,000 = Computerized system: Materials: 50,000/175,000 = Labor: 50,000/75,000 = Materials and labor productivity increase with the acquisition (as claimed by the production manager). 2. To pare the alternatives, all inputs must be considered: Productivity profiles: Current Computerized Materials Labor Capital Energy The productivity profiles indicate a mixed oute—some ratios improve and some do not. Tradeoffs, therefore, must be valued. 3.

The tradeoffs are favorable. The puterized system will increase profits by $97,500. 360 15–11 1.
