CHAPTER 21 (FIN MAN); CHAPTER 6 (MAN) PERFORMANCE EVALUATION USING VARIANCES FROM STANDARD COSTS CLASS DISCUSSION QUESTIONS 1. Standard costs assist management in con- trolling costs and in motivating employees to focus on costs. 2. Management can use standards to assist in achieving control over costs by investigating significant deviations of performance (vari- ances) from standards and taking corrective action. 3. Reporting by the “principle of exceptions” is the reporting of only variances (or “excep- tions”) between standard and actual costs to the individual responsible for cost control. 4. There is no set time period for the revision of standards. They should be revised when prices, product design, labor rates, and manufacturing methods change to such an extent that current standards no longer rep- resent a useful measure of performance. 5. Standard costs for direct materials, direct labor, and factory overhead per unit of product are used in budgetary performance evaluation. Product standard costs are mul- tiplied by the planned production volumes. Budget control is achieved by comparing ac- tual results with the standard costs at actual volumes. 6. a. The two variances in direct materials cost are: (1) Price (2) Quantity or usage b. The price variance is the result of a dif- ference between the actual price and the standard price. It may be caused by such factors as a change in market prices or inefficient purchasing procedures. The quantity or usage variance results from using more or less materials than the standard quantity. It can be caused by such factors as excessive spoilage, care- lessness in the production processes, and the use of inferior materials. 7. The offsetting variances might have been caused by the purchase of low-priced, inferi- or materials. The low price of the materials would generate a favorable materials price variance, while the inferior quality of the ma- terials would cause abnormal spoilage and waste, thus generating an unfavorable ma- terials quantity variance. 8. a. The two variances in direct labor costs are: (1) Rate (price or wage) (2) Time (usage or efficiency) b. The direct labor cost variance is usually under the control of the production su- pervisor. 9. No. Even though the assembly workers are covered by union contracts, direct labor cost variances still might result. For example, direct labor rate variances could be caused by scheduling overtime to meet production de- mands or by assigning higher-paid workers to jobs normally performed by lower-paid work- ers. Likewise, direct labor time variances could result during the training of new workers. 10. a. The variable factory overhead control- lable variance results from incurring a total amount of variable factory over- head cost greater or less than the amount budgeted for the level of opera- tions achieved. The fixed factory over- head volume variance results from oper- ating at a level above or below 100% of normal capacity.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
