material quantity of Kaufmann manufacturing company was way above the budget Question 4(a) Actual power cost= 1‚200‚000 dollars Standard power cost = 1‚200‚000dollars Variance = Actual power cost – standard power cost = 1‚200‚000dollars – 1‚200‚000dollars =0 dollars The total power cost variance equals to 0 dollars. It is therefore seen that the variance is neither favorable nor unfavorable because it is the same amount as the one that is planned for by Kaufmann manufacturing company. Question 4(b)

Computer-integrated manufacturing (CIM) is the manufacturing approach of using computers to control the entire production process.[1][2] This integration allows individual processes to exchange information with each other and initiate actions. Through the integration of computers‚ manufacturing can be faster and less error-prone‚ although the main advantage is the ability to create automated manufacturing processes Before we discuss what an MES is and does‚ we need a brief history lesson on the
