Novack Exercise 102 1 .................................. Number of chopping blocks 4000 ............. Number of board feet per chopping block 2.5 ................................ Standard board feet allowed 10000 ................................ Standard cost per board foot $1.80 .............................................. Total standard cost $18000 ............................................. Actual cost incurred $18700 ............................................ Standard cost above 18000 ................................. Total varianceunfavorable $700 2 Actual Quantity of Inputs, at Actual Price Actual Quantity of Inputs, at Standard Price Standard Quantity Allowed for Output, at Standard Price (AQ AP) (AQ SP) (SQ SP) $18700 11,000 board feet $1.80 per board foot 10,000 board feet $1.80 per board foot = $19,800 = $18,000 Price Variance, $1,100 F Quantity Variance, $1,800 U Total Variance, $700 U Alternatively: Materials Price Variance = AQ (AP SP) 11,000 board feet ($1.70 per board foot* $1.80 per board foot) = $1,100 F *$18,700 11,000 board feet = $1.70 per board foot. Materials Quantity Variance = SP (AQ SQ) $1.80 per board foot (11,000 board feet 10,000 board feet) = $1,800 U Acc ! nting 225 M. Novack Exercise 106 1 Throughput time = Process time + Inspection time + Move time + Queue time = 2.8 days + 0.5 days + 0.7 days + 4.0 days = 8.0 days 2. Only process time is valueadded time; therefore the manufacturing cycle efficiency (MCE) is: 3. If the MCE is 35%, then the complement of this figure, or 65% of the time, was spent in nonvalueadded activities. 4 Delivery cycle time = Wait time + Throughput time = 16.0 days + 8.0 days = 24.0 days 5. If all queue time in production is eliminated, then the throughput time drops to only 4 days (0.5 + 2.8 + 0.7). The MCE becomes: Thus, the MCE increases to 70%. This exercise shows quite dramatically how the lean production approach can improve operations and reduce throughput time. Acc ! nting 225 M. Novack Exercise 109 1. a. Notice in the solution below that the materials price variance is computed on the entire amount of materials purchased, whereas the materials quantity variance is computed only on the amount of materials used in production.variance is computed only on the amount of materials used in production....
