Direct Labor Efficiency Standard:

Definition and Explanation:

Setting direct labor time or efficiency standard means computing the labor time required to complete a unit of product.

The establishment of labor time standard or labor efficiency standard is a specialized function. Therefore they are usually established by industrial engineers using time and motion studies. Standards are set in accordance with scientific methods and accepted practices. They are based on actual performance of worker or group of workers possessing average skill and using average effort while performing manual operations or working on machines operating under normal conditions. Time factors of acceptable level of fatigue, personal needs, and delays beyond the control of the worker are studied and included in the standard. such allowances are an integral part of the labor standard, but time required for setting up machines, waiting, or a break down is included in the factory overhead standard.

The establishment of time standards require a detailed study of manufacturing operations. Standards based on operations should be understood by supervisors and used to enhance labor efficiency. However, time standards are of limited use "where operating times are strongly influenced by factors which cannot be standardized and controlled by management or where output from highly mechanized work is a function of machine time and speed rather than of labor hours worked."

When a new product or process is started, the labor efficiency standard for costing and budget development should be based on learning curve phenomenon. The learning curve may well be, at least in part, an explanation of the labor efficiency variance associated with employees assigned to existing tasks that are new to them. Labor related factory overhead costs and perhaps materials usage might also be affected.


Following is an example of the calculation of standard time required to manufacture a unit of product:

Basic labor time per unit, in hours $1.9
Allowance for breaks and personal needs 0.1
Allowance for cleanup and machine downtime 0.3
Allowance for rejects 0.2
Standard rate per direct labor hour 2.5

After setting labor time and rate standards, the standard labor cost per unit of product can be set. Suppose standard direct labor rate is $14 per hour, the standard cost per unit can be computed as follows:

2.5 hours per unit  $14 per hour = $35 per unit


Real Business Example:

Industrie Natuzzi SpA, founded and r un by Pasquale Natuzzi, produces hand made leather furniture for the world market in Santaeramo Del Colle in southern Italy. Natuzzi is export oriented and has about 25% of U.S. leather furniture market. The company's furniture is hand made by craftsmen, each of whom has a computer terminal that is linked to a sophisticated computer network. The computer provides precise instructions on how to accomplish the task. If the craftsman beats the standard time to complete the task, the computer adds a bonus to the craftsman's pay.

The company's computers know how much thread, screws, foam leather, labor, and so on. is required for every model. "Should the price of Argentinean hides or German dyes rise on day, employees in Santaeramo enter the new prices into the computer, and the costs for all sofas with that leather and those colors are immediately recalculated. ' every thing has to be clear for me,' says Natuzzi. 'Why this penny? Where is it going?'
