Exercise 10-27Â Investigation of Variances
Sommers Company uses the following rule to determine whether materials usage variances should be investigated: A materials usage variance will be investigated anytime the amount exceeds the lesser of $12,000 or 10% of the standard cost. Reports for the past five weeks pro- vided the following information:

1.      Using the rule provided, identify the cases that will be investigated.
2.      CONCEPTUAL CONNECTION Suppose investigation reveals that the cause of an unfavor- able materials usage variance is the use of lower-quality materials than are normally used. Who is responsible? What corrective action would likely be taken?
3.      CONCEPTUAL CONNECTION Suppose investigation reveals that the cause of a significant unfavorable materials usage variance is attributable to a new approach to manufacturing that takes less labor time but causes more material waste. Examination of the labor effi- ciency variance reveals that it is favorable and larger than the unfavorable materials usage variance. Who is responsible? What action should be taken?
