CODIFICATION DEFINITION: • Systematic concise representation of equipment/raw materials/ tools/ spares/ supplies.
INTRODUCTION TO CODIFICATION Due to the growth of industrial activity and diverse kind of industrial requirements, a large no. of organizations have to store a large number of items, often running into several thousands and even lakhs. Therefore, there should be some means of identifying them. A common practice is to describe the items by individual names. Since several departments use the same item, they call the same item by different names and store them in different places. One of the most useful techniques of “Materials Management’’ is a rationalized codification system for properly classifying equipments, raw materials, components and spares to suit to the particular needs of any organization. Old system of functional codification is no longer suitable for the already large and increasing inventory range of stocks and stores. It has come across several instances of duplication of stock of the same item under different nomenclature and codes and under different stores categories where such items are common to more than one consumption center. It is necessary that items are brought together for the purpose standardization, variety reduction and the application of other
modern materials management techniques such as value analysis, operational research etc. so that the maximum return could be secured with the minimum of inventory range and values. Standardization leads to cheaper & easier procurement and cost of replacement can also be reduced.
NEED FOR CODIFICATION The need for Codification arises because of the following reasons: Hundreds of Items: An organization stores large number of items often running into lakhs. Therefore there should be some means of identifying them. A common practise is to describe them by individual names. This creates confusion and complexion in the process. Hence codes are used in order to simplify the process. Eg: At a control depot of a state road transport authority there were 583 hardware items which were reduced to 105 through codification. • Several Departments Related Function: In an organization there are several departments with related functions like storing, deg, procurement, production, buying, selling etc. Different departments call these products by different names. Hence there are complexions and confusions in this process. But this could be made simple through codification. Codification brings in speed, unambiguity, saving of effort, space saving on forms, ease of classification and mechanization. • Unique Common Identification: There should be a unique common identification of items otherwise it causes an unnecessary increase in the inventory level. Eg: An electrical firm found that a simple item like a screw with a width of 3.8 inches and length of 6 inches had as many as 118 names depending upon the type of usage and the department using the screw. Few names are plunger, dowelpin, roller and so on. A proper codification removed the 117 stocking points and with it the associated inventory. • Codes are Logical: The word description are often too long, complex, language related and also without logic. Codes on the other hand are logical, simple, classifying and describing. Eg: Pan number, pin codes etc. •
TYPES OF CODIFICATION Alphabetical: It is an alphabetical representation of codes. Eg: Sulphuric Acid – AC-SU Nitric Acid – AC-NI The above example shows that for a company the code of acid is AC. 2. Numerical: It is a numerical representation of codes. Eg: Pin code, pan number etc. 3. Alpha-numerical: It is a combination of alphabetical and numerical representation of codes. Eg: Car number- MH 02 BF 5434 4. Colour Code: It is a representation of codes through colours. Eg: Private cars – White number plates Taxis – Yellow number plates 1.
METHODS OF CODIFICATION Some of the systems of codification are: Arbitrary System 2.Numerical System 3. Mnemonic System or Alpha Numeric System 4. Decimal System 5. Frisch System 6. Kodak System 1.
1. ARBITARY SYSTEM: Arbitrary system as the word ‘arbitrary’ indicates is based on the serial number under which a material is received and the same is allotted as a code number. Using this approach, all inventory items are simply assigned arbitrary numbers in Sequence as they are added to the stores . Each item thus has a discrete number, but it bears no systematic relationship to the numbers assigned to related items. Two similar items or two mating parts may have numbers several thousand digits apart. For example, if bearings are received and suppose a number 5090 has already been allotted to the previous item received, then the code number of these bearings will be 5091. This system has the advantage that there is no fixed limit for codifying any number of items. Moreover, one cannot know the history of the items. This is the reason why the system is not popular. 2. NUMERICAL SYSTEM: A numerical system assigns a six to ten digit code number to each item. The first several numbers usually indicate the classification to which the item belongs; the next several numbers typically indicate the sub-class, and the last three numbers are usually encoded. The following example illustrates the concept:
3 129 017 503 General Class Generic Class Sub-class Specific item number This ten digit code number is one firm’s stock number for a ¼ by ¾ inch stainless steel square neck carriage bolt. The first digit indicates that the item is a purchased part as per the following general classification: i. Raw material ii. Manufactured parts iii. Purchased parts iv. MRO supplies v. Work in process The next three digits indicate the generic classification of the item. In this case it is a fastener, code number 129. All items are generically classified by their nature and carry a number from 000 to 999. The next three digits indicate the sub-class to which the item belongs. In this case, 017 is a carriage bolt with a square neck. All fasteners are sub-classified into a class bearing number from 000 to 999. The last three digits indicate the specific part number of the item. In this case, all part numbers under 500 designate plain steel and numbers over 500 represent various alloys; 503 is stainless steel, ¼ by ¾ inch. 3. MNEMONIC SYSTEM: A mnemonic system functions much like a numerical system. However, it combines numeric and alphabetic notations in its symbols. For example, the carriage bolt described under the numerical system in the following manner: P Far BCS 503 • P denotes a purchased part • Far is a fastener • BCS stands for bolt, carriage, with a square neck • 503 represents the specific number of the bolt. Mnemonic systems, particularly where a small number of items are involved, frequently make visual identification easier because
they are more descriptive and they are often shorter. As more and different types of items are added to the Inventory, however, this advantage diminishes because the numbers of good symbols are limited. 4. DECIMAL SYSTEM: Decimal system of codification may said to be the universal in its working. It is simple and easy to codify items under this system. Day by day, the number of items in almost every sphere of industry is increasing. Hence, codifications should Be such as may meet the increasing requirements and it should also be simple, handy and easily adaptable. Under this system items up to 5, 00,000 can be easily codified and at the same time each symbol will give the history, size, specification And complete picture of the item. Modern industrial concerns are generally adopting 7 to 11 digits for codifying the materials. In the decimal codification system, each digit indicates something or the other. For example: • 1st digit -Section • 2nd digit -Class • 3rd digit -Group • 4th digit -Type of materials • 5th digit -Size, part no. specification or any other details required Example: Section 0 — Plants and machinery 1 — Machine and hand tools 2 — Construction materials etc. Class 0 — Hand tools (For section-1) 1 — Machine tools 3 — Cutting tools 2 — holding tools 4 — tripped cutting tools etc. Group 0 — Cutters(For section-1) 1 — Files 2 — Knurls
3 — Scrapper etc.
Suppose a file flat, single cut smooth, size 25 mm is to be codified. It will be indicated by 1st, 2nd and 3rd digits as 131. Further fourth and fifth digit will be classified as: 4th digit to indicate the shape of the file, thus 0 — for flat 3 — for round 1 — for hand 4 — for tapered etc. 2 — for sure 5the digit to indicate the teeth of file, thus 0 — for single cut, rough 2 — for single cut, smooth 1 — for single cut, coarse 3 — for double cut, coarse etc. The 6th, 7th and 8th digits indicate the size of the file in mm. Therefore, file flat, single cut smooth size 25 mm will be codified as – 13102025. 5. BRISCH SYSTEM: The Frisch system consists of seven digits applied in three stages. The items are grouped into suitable preliminary categories, such as assemblies, sub-assemblies, components and off the shelf items. After these preliminary categories, items are grouped within the respective class in order to bring similar items together. The Frisch system through it consists only of seven digits, is quite comprehensive as the basis is on logical major groupings. 6. KODAK SYSTEM: The Kodak system consists of 10 digits of numerical code. The logic of major grouping is based on sources of supply. All materials are divided into 100 basic classifications, contributed only by procurement considerations. For instance, a bolt is listed as hardware item if this is listed in hardware catalogues and available with hardware suppliers. If this bolt is available as a part of the machine, it will be available under maintenance.
ADVANTAGES OF CODIFICATION Let us discuss some advantages of codification in material management: a. As a result of rationalized codification, many firms have reduced the number of items. b.It enables systematic grouping of similar items and avoids confusion caused by long description of the items. c. Since standardization of names is achieved through codification, it serves as the starting point of simplification and standardization. d.It helps in avoiding duplication of items and results in the minimization of the number of items, leading to accurate records. e. Codification enables easy recognition of an item in stores, thereby reducing clerical efforts to be minimum. f. If items are coded according to the sources, it is possible to bulk the items while ordering.
STANDARDIZATION. DEFINITION • Standardization is reduction of the number of similar items held in stock, therefore reducing overall stock holdings of the organization.
INTRODUCTION TO STANDARDIZATION Mass production techniques of industrial production are based on the principle of uniformity and interchangeability of many parts, components and material used in the production process. Standard products can be manufactured on a mass scale and their production cost can be kept minimum. Standardization leads to cheaper and easier procurement and cost of replacement can also be reduced. Standardization s the fundamental precepts of build-toorder and mass customization: All parts must be available at all points of use, not just "somewhere in the plant," which eliminates the setup to find, load, or kit parts. As a stand-alone program, standardization can reduce cost and improve flexibility. Standardization makes it easier for parts to be pulled into assembly (instead of ordering and waiting) by reducing the number of part types to the point where the remaining few standard parts can receive the focus to arrange demand-pull justin-time deliveries. Fewer types of parts ordered in larger quantities reduce part cost and material overhead cost.
NEED FOR STANDARDIZATION Uniform Quality: Standardization ensures Uniform Quality of both, the INCOMING Raw Materials as well as the OUTGOING Finished goods. 1.
Uniform Communication: Standardization ensures stable and clear communication between the various departments, operating within the Organisation. This is also leads to better communication of the Organisation with its Suppliers and Customers. 2.
Total Overall Quality: Standardization is required so that the Organisation and its Products can achieve certain amount of goodwill in the market. This in turn, also increases the Reliability factor of the Organisation and its products, with its customers and suppliers. 3.
Platform for Sound Inventory Analysis: Standardization means, reducing the Total Overall stock holdings of the Organisation. A reduced level of Inventory or stock holdings means that the Critical Inventory analysis which is essential, becomes Lucid and also happens in a smooth flow. 4.
PROCESS OF STANDARDIZATION Steps involved in standardization procedure are as follows: Codify: In this step, all the Individual inventory items are codified according to the similarities in their attributes, etc. 1.
Identify: The next step involves identifying the similar items, and placing them in large groups, which are categorized according to the similar attributes and various other factors. 2.
Select Best: This is the most important step. After critically analyzing all the large groups of similar items, the Organization selects the best choice. Various factors are taken into consideration while making the right choice, i.e. Price, Performance, Usage, Life period, etc. 3.
Reduce New Stock Level: The final step involved is to analysis the new, reduced level of the stock holdings. Indirectly, the stock cost of the organization also decreases due to this. 4.
APPLICATION OF STANDARIZATION SIZE: Products can be standardized based on their sizes. Eg: A shoe of size 8 and size 10 are standardized and kept differently. 2. DIMENSION: Products can also be standardized based on their dimensions. Eg: Ceiling fans are of different dimensions. 3. CONTENT: Products are standardized based on their content. Eg: Shoes made of leather and those made of cloth are kept separately. 4. CLASS/GRADE: Products can also be standardized based on their class or grade. Eg: Shoes made of leather are of a higher class than those made of cloth or rubber. 5. LIFE SPAN: Products can also be standardized based on their life span. Eg: Perishable and non-perishable products. 1.
Standardization can be applied to a major extent in the following fields: 1) Finished products, e.g., cars and televisions. 2) Sub-assemblies and components, e.g., automobile gearboxes and auto electric bulbs. 3) Material Standardization, e.g., both of direct materials (plain carbon and alloy steels, are welding electrode core wires, etc.) and indirect materials (such as oils and greases). 4) Production equipment standardization, e.g., that of machine tools, presses, welding equipments, etc.
ADVANTAGES OF STANDARDIZATION Let us discuss some advantages of standardization in material management. 1. QUOTATION COMPARISON: Standardization helps us to compare the various products depending on the quotations or price levels. A product of higher standard or quality will be priced higher than a product of lower quality. This helps the buyer to choose between the products according to his needs. 2.
REDUCES STOCK LEVEL: Standardizing the inventory helps reduce the stock level since the seller gets to know what exact raw materials and of what quality he needs in order to produce a particular product and will avoid the purchase of unwanted materials. Eg: If a producer buys 10 units each of raw materials from 4 different suppliers, after standardization he will buy 10 units each of raw materials from only 2 suppliers hence reducing the stock levels.
3.
BETTER INVENTORY ANALYSIS & REDUCES INSPECTION TIME: Since the producer now knows the exact raw materials he is using and also since the stock level has reduced, this will enable him to analyse his inventory more efficiently and will considerably reduce the time required for inspection.
4.
ENHANCES PRODUCTIVITY: Standardization of materials helps to enhance the productivity of an organisation. Due to standardization of raw materials a production unit can put them in the machines together which can run consistently for a longer time and hence enhance the productivity of an organisation.
5.
REDUCES HANDLING COST: Standardization reduces handling costs. The handling cost of different materials is
different. By standardizing them their handling costs can reduce considerably. Eg: The handling cost leather is higher than that of cloth. If leather and cloth are not kept separately in the inventory and handled together, the handling cost of cloth becomes equal to that of leather. Hence there is a need to handle them differently in order to reduce costs. 6.
CLEAR COMMUNICATION: Standardization helps clear and effective communication the seller and supplier. Since the supplier knows what exactly the seller wants, he can supply accordingly. Similar is the case with the seller and the buyer.
•
LIMITATIONS TO STANDARDIZATION However, there are some disadvantages also, that are attached with standardization. 1. Reduction in choice because of reduced variety and consequent loss of business or customers. 2. Changes in public taste seriously affect a company producing only standardized product range. 3. It becomes difficult to introduce new models because of less flexible (existing) production facilities and due to the high cost of specialized production equipment. 4.
Standardization tends to favour large famous companies because small or new concerns can rarely get much business even by producing same items and by selling them at the same price as the big companies.
5.
Standards once set, resist change and thus standardization may become an obstacle to progress.
