Answer:
efficiency variance
Step-by-step explanation:
When standard direct labor hours differ from actual direct labor hours used, the company experienced an "efficiency varaiance". It can be used in order to analyze how effective an operation is in relation to labor, materials, machine time and other production factors.
Efficiency variance is actually the difference which exists between the theoretical amount of inputs which are needed to produce an output and the actual number of inputs which are required to manufacture the unit of output.
