Introduction
You know that management accounting is managing a business through accounting information. In this process, management accounting is facilitating managerial control. It can also be applied to your own daily/monthly expenses, if necessary. These measures should be applied correctly so that performance takes place according to plans. Planning is the first tool for making the control effective. The vital aspect of managerial control is cost control. Hence, it is very important to plan and control costs. Standard costing is a technique which helps you to control costs and business operations. It aims at eliminating wastes and increasing efficiency in performance through setting up standards or formulating cost plans.
Meaning of Standard
When you want to measure some thing, you must take some parameter or yardstick for measuring. We can call this as standard. What are your daily expenses? An average of $50! If you have been spending this much for so many days, then this is your daily standard expense.
The word standard means a benchmark or yardstick. The standard cost is a predetermined cost which determines in advance what each product or service should cost under given circumstances.
In the words of Backer and Jacobsen, “Standard cost is the amount the firm thinks a product or the operation of the process for a period of time should cost, based upon certain assumed conditions of efficiency, economic conditions and other factors.”
Definition
The CIMA, London has defined standard cost as “a predetermined cost which is calculated from managements standards of efficient operations and the relevant necessary expenditure.” They are the predetermined costs on technical estimate of material labor and overhead for a selected period of time and for a prescribed set of working conditions. In other words, a standard cost is a planned cost for a unit of product or service rendered.
The technique of using standard costs for the purposes of cost control is known as standard costing. It is a system of cost accounting which is designed to find out how much should be the cost of a product under the existing conditions. The actual cost can be ascertained only when production is undertaken. The predetermined cost is compared to the actual cost and a variance between the two enables the management to take necessary corrective measures.
Advantages
Standard costing is a management control technique for every activity. It is not only useful for cost control purposes but is also helpful in production planning and policy formulation. It allows management by exception. In the light of various objectives of this system, some of the advantages of this tool are given below:
1. Efficiency measurement-- The comparison of actual costs with standard costs enables the management to evaluate performance of various cost centers. In the absence of standard costing system, actual costs of different period may be compared to measure efficiency. It is not proper to compare costs of different period because circumstance of both the periods may be different. Still, a decision about base period can be made with which actual performance can be compared.
2. Finding of variance-- The performance variances are determined by comparing actual costs with standard costs. Management is able to spot out the place of inefficiencies. It can fix responsibility for deviation in performance. It is possible to take corrective measures at the earliest. A regular check on various expenditures is also ensured by standard cost system.
3. Management by exception-- The targets of different individuals are fixed if the performance is according to predetermined standards. In this case, there is nothing to worry. The attention of the management is drawn only when actual performance is less than the budgeted performance. Management by exception means that everybody is given a target to be achieved and management need not supervise each and everything. The responsibilities are fixed and every body tries to achieve his/her targets.
4. Cost control-- Every costing system aims at cost control and cost reduction. The standards are being constantly analyzed and an effort is made to improve efficiency. Whenever a variance occurs, the reasons are studied and immediate corrective measures are undertaken. The action taken in spotting weak points enables cost control system.
5. Right decisions-- It enables and provides useful information to the management in taking important decisions. For example, the problem created by inflating, rising prices. It can also be used to provide incentive plans for employees etc.
6. Eliminating inefficiencies-- The setting of standards for different elements of cost requires a detailed study of different aspects. The standards are set differently for manufacturing, administrative and selling expenses. Improved methods are used for setting these standards. The determination of manufacturing expenses will require time and motion study for labor and effective material control devices for materials. Similar studies will be needed for finding other expenses. All these studies will make it possible to eliminate inefficiencies at different steps.
Limitations of Standard Costing
1. It cannot be used in those organizations where non-standard products are produced. If the production is undertaken according to the customer specifications, then each job will involve different amount of expenditures.
2. The process of setting standard is a difficult task, as it requires technical skills. The time and motion study is required to be undertaken for this purpose. These studies require a lot of time and money.
3. There are no inset circumstances to be considered for fixing standards. The conditions under which standards are fixed do not remain static. With the change in circumstances, if the standards are not revised the same become impracticable.
4. The fixing of responsibility is not an easy task. The variances are to be classified into controllable and uncontrollable variances. Standard costing is applicable only for controllable variances.
For instance, if the industry changed the technology then the system will not be suitable. In that case, we will have to change or revise the standards. A frequent revision of standards will become costly.
Setting Standards
Normally, setting up standards is based on the past experience. The total standard cost includes direct materials, direct labor and overheads. Normally, all these are fixed to some extent. The standards should be set up in a systematic way so that they are used as a tool for cost control.
Various Elements which Influence the Setting of Standards
Setting Standards for Direct Materials
There are several basic principles which ought to be appreciated in setting standards for direct materials. Generally, when you want to purchase some material what are the factors you consider. If material is used for a product, it is known as direct material. On the other hand, if the material cost cannot be assigned to the manufacturing of the product, it will be called indirect material. Therefore, it involves two things:
• Quality of material
• Price of the material
When you want to purchase material, the quality and size should be determined. The standard quality to be maintained should be decided. The quantity is determined by the production department. This department makes use of historical records, and an allowance for changing conditions will also be given for setting standards. A number of test runs may be undertaken on different days and under different situations, and an average of these results should be used for setting material quantity standards.
The second step in determining direct material cost will be a decision about the standard price. Material’s cost will be decided in consultation with the purchase department. The cost of purchasing and store keeping of materials should also be taken into consideration. The procedure for purchase of materials, minimum and maximum levels for various materials, discount policy and means of transport are the other factors which have bearing on the materials cost price. It includes the following:
• Cost of materials
• Ordering cost
• Carrying cost
The purpose should be to increase efficiency in procuring and store keeping of materials. The type of standard used-- ideal standard or expected standard-- also affects the choice of standard price.
Setting Direct Labor Cost
If you want to engage a labor force for manufacturing a product or a service for which you need to pay some amount, this is called wages. If the labor is engaged directly to produce the product, this is known as direct labor. The second largest amount of cost is of labor. The benefit derived from the workers can be assigned to a particular product or a process. If the wages paid to workers cannot be directly assigned to a particular product, these will be known as indirect wages. The time required for producing a product would be ascertained and labor should be properly graded. Different grades of workers will be paid different rates of wages. The times spent by different grades of workers for manufacturing a product should also be studied for deciding upon direct labor cost. The setting of standard for direct labor will be done basically on the following:
• Standard labor time for producing
• Labor rate per hour
Standard labor time indicates the time taken by different categories of labor force which are as under:
• Skilled labor
• Semi-skilled labor
• Unskilled labor
For setting a standard time for labor force, we normally take in to account previous experience, past performance records, test run result, work-study etc. The labor rate standard refers to the expected wage rates to be paid for different categories of workers. Past wage rates and demand and supply principle may not be a safe guide for determining standard labor rates. The anticipation of expected changes in labor rates will be an essential factor. In case there is an agreement with workers for payment of wages in the coming period, these rates should be used. If a premium or bonus scheme is in operation, then anticipated extra payments should also be included. Where a piece rate system is used, standard cost will be fixed per piece. The object of fixed standard labor time and labor rate is to device maximum efficiency in the use of labor.
Setting Standards of Overheads
The next important element comes under overheads. The very purpose of setting standard for overheads is to minimize the total cost. Standard overhead rates are computed by dividing overhead expenses by direct labor hours or units produced. The standard overhead cost is obtained by multiplying standard overhead rate by the labor hours spent or number of units produced. The determination of overhead rate involves three things:
• Determination of overheads
• Determination of labor hours or units manufactured
• Calculating overheads rate by dividing A by B
The overheads are classified into fixed overheads, variable overheads and semi-variable overheads. The fixed overheads remain the same irrespective of level of production, while variable overheads change in the proportion of production. The expenses increase or decrease with the increase or decrease in output. Semi-variable overheads are neither fixed nor variable. These overheads increase with the increase in production but the rate of increase will be less than the rate of increase in production. The division of overheads into fixed, variable and semi-variable categories will help in determining overheads.
Determination of Standard Costs
How should the ideal standards for better controlling be determined?
1. Determination of Cost Center
According to J. Betty, “A cost center is a department or part of a department or an item of equipment or machinery or a person or a group of persons in respect of which costs are accumulated, and one where control can be exercised.” Cost centers are necessary for determining the costs. If the whole factory is engaged in manufacturing a product, the factory will be a cost center. In fact, a cost center describes the product while cost is accumulated. Cost centers enable the determination of costs and fixation of responsibility. A cost center relating to a person is called personnel cost center, and a cost center relating to products and equipments is called impersonal cost center.
2. Current Standards
A current standard is a standard which is established for use over a short period of time and is related to current condition. It reflects the performance that should be attained during the current period. The period for current standard is normally one year. It is presumed that conditions of production will remain unchanged. In case there is any change in price or manufacturing condition, the standards are also revised. Current standard may be ideal standard and expected standard.
3. Ideal Standard
This is the standard which represents a high level of efficiency. Ideal standard is fixed on the assumption that favorable conditions will prevail and management will be at its best. The price paid for materials will be lowest and wastes etc. will be minimum possible. The labor time for making the production will be minimum and rates of wages will also be low. The overheads expenses are also set with maximum efficiency in mind. All the conditions, both internal and external, should be favorable and only then ideal standard will be achieved.
Ideal standard is fixed on the assumption of those conditions which may rarely exist. This standard is not practicable and may not be achieved. Though this standard may not be achieved, even then an effort is made. The deviation between targets and actual performance is ignorable. In practice, ideal standard has an adverse effect on the employees. They do not try to reach the standard because the standards are not considered realistic.
4. Basic Standards
A basic standard may be defined as a standard which is established for use for an indefinite period which may a long period. Basic standard is established for a long period and is not adjusted to the preset conations. The same standard remains in force for a long period. These standards are revised only on the changes in specification of material and technology productions. It is indeed just like a number against which subsequent process changes can be measured. Basic standard enables the measurement of changes in costs. For example, if the basic cost for material is Rs. 20 per unit and the current price is Rs. 25 per unit, it will show an increase of 25% in the cost of materials. The changes in manufacturing costs can be measured by taking basic standard, as a base standard cannot serve as a tool for cost control purpose because the standard is not revised for a long time. The deviation between standard cost and actual cost cannot be used as a yardstick for measuring efficiency.
5. Normal Standards
As per terminology, normal standard has been defined as a standard which, it is anticipated, can be attained over a future period of time, preferably long enough to cover one trade cycle. This standard is based on the conditions which will cover a future period of five years, concerning one trade cycle. If a normal cycle of ups and downs in sales and production is 10 years, then standard will be set on average sales and production which will cover all the years. The standard attempts to cover variance in the production from one time to another time. An average is taken from the periods of recession and depression. The normal standard concept is theoretical and cannot be used for cost control purpose. Normal standard can be properly applied for absorption of overhead cost over a long period of time.
6. Organization for Standard Costing
The success of standard costing system will depend upon the setting up of proper standards. For the purpose of setting standards, a person or a committee should be given this job. In a big concern, a standard costing committee is formed for this purpose. The committee includes production manager, purchase manager, sales manager, personnel manager, chief engineer and cost accountant. The cost accountant acts as a co-coordinator of this committee.
7. Accounting System
Classification of accounts is necessary to meet the required purpose, i.e. function, asset or revenue item. Codes can be used to have a speedy collection of accounts. A standard is a pre-determined measure of material, labor and overheads. It may be expressed in quality and its monetary measurements in standard costs.
Revision of Standards
For effective use of this technique, sometimes we need to revise the standards which follow for better control. Even standards are also subjected to change like the production method, environment, raw material, and technology.
Standards may need to be changed to accommodate changes in the organization or its environment. When there is a sudden change in economic circumstances, technology or production methods, the standard cost will no longer be accurate. Standards that are out of date will not act as effective feed forward or feedback control tools. They will not help us to predict the inputs required nor help us to evaluate the efficiency of a particular department. If standards are continually not being achieved and large deviations or variances from the standard are reported, they should be carefully reviewed. Also, changes in the physical productive capacity of the organization or in material prices and wage rates may indicate that standards need to be revised. In practice, changing standards frequently is an expensive operation and can cause confusion. For this reason, standard cost revisions are usually made only once a year. At times of rapid price inflation, many managers have felt that the high level of inflation forced them to change price and wage rate standards continually. This, however, leads to reduction in value of the standard as a yardstick. At the other extreme is the adoption of basic standard which will remain unchanged for many years. They provide a constant base for comparison, but this is hardly satisfactory when there is technological change in working procedures and conditions.
Summary
Basically, standard costing is a management tool for control. In the process, we have taken standards as parameters for measuring the performance. Cost analysis and cost control is essential for any activity. Cost includes material labor and overheads. Sometimes, we need to revise the standards due to change in uses, raw material, technology, method of production etc. For a proper organization, it is required to implement this under a committee for the activity. It is a continued activity for the optimum utilization of resources.

PDCA Cycle - Example

Personal Improvement
The PDCA cycle is a valuable process that can be applied to practically anything. In this session, we discuss case related medical student performance, but the PDCA cycle can be used in everything from making a meal to walking your dog. An immediate concern of yours may be improving your study skills.

Example 1: The Student with Poor Grades

Lakshmi is a first-year medical student who has just taken her first set of examinations and is very unhappy with the results.
• What is she trying to accomplish? Lakshmi knows that she needs to improve her studying skills in order to gain a better understanding of the material.

• How will she know that a change is an improvement? Lakshmi considers the most important measure of her study skills to be her exam grades. However, she does not want to risk another exam period just to find out that her skills are still not good. She decides that a better way to measure improvement is by taking old exams.

• What changes can she make that will result in improvement? Lakshmi thinks that she has spent too little time studying. She feels that the best way to improve her study skills is by putting in more hours.
Cycle 1

Plan: Lakshmi decides to add an additional thirty hours per week to her already busy schedule. She resolves that she must socialize less, get up earlier, and stay up later. At the end of the week she will take an old exam to see how she is progressing.

Do: By the end of the week, Lakshmi finds that she was able to add only fifteen hours of studying. When she takes the exam she is dismayed to find that she does no better.

Check: The fifteen extra hours of studying has made Lakshmi feel fatigued. In addition, she finds that her ability to concentrate during those hours is rather limited. She has not exercised all week and has not seen any of her friends. This forced isolation is discouraging her.

Act: Lakshmi knows that there must be another way. She needs to design a better, more efficient way to study that will allow her time to exercise and socialize.
Cycle 2
Plan: Lakshmi contacts all her medical school friends who she knows are doing well yet still have time for outside lives. Many of these friends have similar advice that Lakshmi thinks she can use. Based on her findings, she decides to always attend lectures, to rewrite her class notes in a format she can understand and based on what the professor has emphasized, and to use the assigned text only as a reference.
Do: Lakshmi returns to her original schedule of studying. However, instead of spending a majority of her time poring over the text, she rewrites and studies her notes. She goes to the text only when she does not understand her notes. When Lakshmi takes one of the old exams, she finds that she has done better, but she still sees room for improvement.
Check: Lakshmi now realizes that she had been spending too much time reading unimportant information in the required text. She knows that her new approach works much better, yet she still feels that she needs more studying time. She is unsure what to do, because she doesn't want to take away from her social and physically active life.
Act: Lakshmi decides to continue with her new studying approach while attempting to find time in her busy day to study more.
Cycle 3
Plan: In her search for more time to study, Lakshmi realizes that there are many places that she can combine exercising and socializing with studying. First, she decides to study her rewritten notes while she is exercising on the Stairmaster. Next, she intends to spend part of her socializing time studying with her friends.

Do: Lakshmi's friends are excited about studying together, and their sessions turn into a fun and helpful use of everyone's time. Lakshmi has found that she enjoys studying while she exercises. In fact, she discovers that she remains on the Stairmaster longer when she's reading over her notes. When Lakshmi takes her exams this week, she is happy to find that her grades are significantly higher.

Check: Lakshmi now knows that studying does not mean being locked up in her room reading hundreds of pages of text. She realizes that she can gain a lot by studying in different environments while focusing on the most important points.

Act: Lakshmi chooses to continue with the changes she has made in her studying habits. What Lakshmi initially thought would be an improvement turned out to only discourage her further. Many people who are in Lakshmi's place do not take the time to study their changes and continue them even though they lead down a disheartening path. By using the PDCA cycle, Lakshmi was able to see that her initial change did not work and that she had to find one that would better suit her. With perseverance and the willingness to learn, Lakshmi was able to turn a negative outcome into a positive improvement experience.
