Final answer:
Combining the direct labor rate variance with the direct labor efficiency variance gives us the direct labor total variance, indicating the overall performance of labor cost management.
Step-by-step explanation:
Combining the direct labor rate variance with the direct labor efficiency variance is a way to compute the direct labor total variance.
Direct labor rate variance measures the difference between the actual hourly labor cost and the standard or expected labor cost for the actual hours worked, reflecting how well a company manages labor costs. Meanwhile, the direct labor efficiency variance compares the actual number of hours worked to produce a certain number of units with the expected hours to determine efficiency in using labor hours. When these two variances are combined, they reveal the overall performance of labor cost management in relation to both the cost rate and the amount of labor used.
In a production setting, labor is considered a variable cost, meaning it fluctuates with the level of output. More output requires more labor, thus increasing variable costs. This includes both the direct labor employed to produce goods or services and the raw materials used in production.
