  3. Compute the direct labor rate and efficiency variance and explain their significance.
  4. Compute the manufacturing overhead spending and efficiency variance.

In this section of the website we study management control and performance measures. Quite often, these terms carry with them negative connotations – we may have a tendency to think of performance measurement as something to be feared. And indeed, performance measurements can be used in very negative ways – to cast blame and to punish. However, that is not the way they should be used. Performance measurement serves a vital function in both personal life and in organizations. Performance measurement can provide feedback concerning what works and what does not work, and it can help motivate people to sustain their efforts.

In this section we see how various measures are used to control operations and to evaluate performance. Even though we are starting with the lowest levels in the organization, keep in mind that performance measures should be derived from the organization’s overall strategy. For example, a company like Sony that bases its strategy on rapid introduction of innovative consumer products should use different performance measures than a company like Federal Express where on-time delivery, customer convenience, and low cost are key competitive advantages. Sony may want to keep close track of the percentage of revenues from products introduced within the last year; whereas Federal Express may want to closely monitor the percentage of packages delivered on time.¬† Later in this section when we discuss the balance scorecard, we will have more to say concerning the role of strategy in the selection of performance measures. But first we will see how standard costs are used by managers to help control costs.

Company in highly competitive industries like Federal Express, Southwest airlines, Dell Computer, Shell Oil, and Toyota must be able to provide high quality goods and services at low cost. If they do not, they will perish. Stated in the starkest terms, managers must obtain inputs such as raw materials and electricity at the lowest possible prices and must use them as effectively as possible – while maintaining or increasing the quality of the output. If inputs are purchased at prices that are too high or more inputs are used than is really necessary, higher costs will result.

How do managers control the prices that are paid for inputs and the quantities that are used? They could examine every transaction in detail, but this obviously would be an inefficient use of management time. For many companies, the answer to this control problem lies at least partially in standard costing system.

Standard Costs and Management By Exception:

A standard cost is the predetermined cost of manufacturing a single unit or a number of product units during a specific period in the immediate future. It is the planned cost of a product under current and/or anticipated operating conditions. Click here to read full article.

Setting Standard Costs – Ideal Versus Practical Standards:

Setting price and quantity standards requires the combined expertise of all persons who have responsibility over input prices and over effective use of inputs. In a manufacturing firm, this might include accountants, purchasing managers, engineers, production supervisors, line mangers, and production workers. Past records of purchase prices and input usage can help in setting standards. However, the standards should be designed to encourage efficient future operations, not a repetition of past inefficient operations. Click here to read full article.

Direct Materials Standards and Variance Analysis:

Direct Materials Price and Quantity Standards:

Standard price per unit of direct materials is the price that should be paid for a single unit of materials, including allowances for quality, quantity purchased, shipping, receiving, and other such costs, net of any discounts allowed. Click her to read full article.

Direct Materials Price Variance:

Direct materials price variance is the difference between the actual purchase price and standard purchase price of materials. Direct materials price variance is calculated either at the time of purchase of direct materials or at the time when the direct materials are used. Click here to read full article

Direct Materials Quantity Variance:

Direct materials quantity variance or Direct materials usage variance measures the difference between the quantity of materials used in production and the quantity that should have been used according to the standard that has been set. Although the variance is concerned with the physical usage of materials, it is generally stated in dollar terms to help gauge its importance. Click here to read full article.

Direct Labor Standards and Variance Analysis:

Direct Labor Rate and Efficiency Standards:

Direct labor price and quantity standards are usually expressed in terms of a labor rate and labor hours. The standard rate per hour for direct labor includes not only wages earned but also fringe benefit and other labor costs. Click here to read full article.

Direct Labor Rate/Price Variance:

Direct Labor price variance is also termed as direct labor rate variance. This variance measures any deviation from standard in the average hourly rate paid to direct labor workers. Click here to read full article.

Direct Labor Efficiency | Usage | Quantity Variance:

The quantity variance for direct labor  is generally called direct labor efficiency variance or direct labor usage variance. Click here to read full article.

Manufacturing Overhead Standards and Variance Analysis:

Manufacturing Overhead Standards:

Procedures for the establishing and using standard factory overhead rates are similar to the methods of dealing with the estimated direct and indirect factory overhead and its application to jobs and products. Click here to read full article.

Factory Overhead Variances:

Jobs or processes are charged with cost on the basis of standard hours allowed multiplied by the standard factory over head rate. The standard overhead rate or predetermined overhead rateis discussed in detail at our job order costing system page. The standard hours allowed figure is determined by multiplying the labor hours required to produce one unit (the standard labor hours per unit) times the actual number of units produced during the period. The units produced are the equivalent units of production for the departmental factory overhead cost being analyzed. At the end of the month, overhead actually incurred is compared with the expenses charged into process using the standard factory overhead rate. The difference between these figures is called the overall or net factory overhead variance.

overall or net factory overhead variance needs further analysis to reveal detailed causes for the variance and to guide management toward remedial action. This analysis may be made by using (1) the two variance method, (2) the three variance method, or (3) the four variance method.

The two variance method: When an overall or net factory overhead variance is further analyzed by using two variance approach, the following two variances are calculated:

  1. Controllable variance
  2. Volume variance

The three variance method: When an overall or net factory overhead variance is further analyzed by using three variance approach, the following three variances are calculated:

  1. Spending variance
  2. Idle capacity variance
  3. Efficiency variance

The four variance method: When an overall or net factory overhead variance is further analyzed by using four variance approach, the following four variances are calculated:

  1. Spending variance
  2. Variable efficiency variance
  3. Fixed efficiency variance
  4. Idle capacity variance

Mix and Yield Variance – Definition and Explanation:

Basically, the establishment of standard product cost requires the determination of price and quantity standards. In many industries, particularly of the process type, materials mix and materials yield play significant parts in the final product cost, in cost reduction, and in profit improvement.

Calculation of Mix and Yield Variances:

  1. Materials Mix and Yield Variance
  2. Labor Yield Variance
  3. Factory Overhead Yield variance

Variance Analysis and Management By Exception:

Variance analysis and performance reports are important elements of management by exception. Simply put, management by exception means that the manager’s attention should be directed toward those parts of the organization where plans are not working out for reason or another.

Managerial importance and usefulness of variance analysis:

Costs of production are effected by internal factors over which management has a large degree of control. An important job of executive management is to help the members of various management levels understand that all of them are part of the management team. Click here to read full article.

Advantages and Disadvantages of Standard Costing System:

The use of standard costs is a key element in a management by exception approach. If costs remain within the standards, Managers can focus on other issues. Click here to read full article
