Materials Management
Material management is an approach for planning, organizing, and controlling all those activities principally concerned with the flow of materials into an organization
Material Management System
Material Management System
Objectives:The fundamental objectives of the Materials Management function ,often called the famous 5 Rs of Materials Management, are acquisition of materials and services:
• of the right quality• in the right quantity• at the right time• from the right source•at the right price
Material Management System
From the management point of view , the key objectives of Material Management are :
•To buy at the lowest price , consistent with desired quality and service•To maintain a high inventory turnover , by reducing excess storage , carrying costs and inventory losses occurring due to deteriorations , obsolescence and pilferage•To maintain continuity of supply , preventing interruption of the flow of materials and services to users•To maintain the specified material quality level and a consistency of quality which permits efficient and effective operation.
Material Management System
•To develop reliable alternate sources of supply to promote a competitive atmosphere in performance and pricing•To minimize the overall cost of acquisition by improving the efficiency of operations and procedures •To hire, develop, motivate and train personnel and to provide a reservoir of talent
Material Management System
•To develop and maintain good supplier relationships in order to create a supplier attitude and desire furnish the organization with new ideas , products, and better prices and service•To achieve a high degree of cooperation and coordination with user departments•To maintain good records and controls that provide an audit trail and ensure efficiency and honesty•To participate in Make or Buy decisions

PURCHASES OF PRODUCTIVE MATERIALS
Purchasing Forms
Purchase Requisition:
The purchase requisition originates with:
•A stores or warehouse clerk, who observes that the quantity on hand is at a set ordering minimum,•A materials ledger clerk, who may be responsible for notifying the purchasing agent when to buy,
Material Management System
•A works manager, who foresees the need for materials or unusual quantities•A research, engineering or other department employee or supervisor who needs materials or supplies of special nature, or•An information system that has been installed or developed to produce replenishment advice for the purchasing department.•One copy remains with the originator, and the original is sent to the purchasing department.
Material Management System
The purchase order, signed by is a written authorization to a vendor to supply specified quantities of described goods at agreed terms and at designated time and place. The purchase order gives the vendor a complete description of the goods and services described the terms, the prices, and the shipping instructions.

ISSUING AND COSTING OF MATERIALS
To control the quantity and cost of materials, supplies, and services requires a systematic and efficient system of purchasing, recording, and storing. Equally necessary is a systematic and efficient procedure for issuing materials and supplies.
Material Management System
ISSUING AND COSTING OF MATERIALS
Material Requisition:The materials requisition is a written order to the storekeeper to deliver materials or supplies to the place designated or to give the materials to the person presenting a properly executed requisition.
Material Management System
SPECIMEN OF MATERIAL REQUISITION

ISSUING AND COSTING OF MATERIALSMaterial Requisition Journals:
Material Requisitioned Journal is necessary to post the materials withdrawals from the store. The journal is form of materials summary. At the end of the month, the totals of the various columns are posted directly to the ledger accounts.
Material Management System
ISSUING AND COSTING OF MATERIALSBill of Materials:
The bill materials, a kind of master requisition, are a printed or duplicated form that lists all materials and parts necessary for a typical job or production run. Time is saved and efficiency is promoted through the use of a bill of materials. When a job or production run is started, all the materials listed on the bill of materials are sent to the factory are issued on a pre arranged time schedule.
Material Management System
ISSUING AND COSTING OF MATERIALSJust-In-Time Inventory Procedures:Manufacturing processes are increasingly being based on the receipt of raw materials from suppliers “Just-In-Time” for their use on the plant floor.When a firm’s raw materials can be handled in this immediate use mode, the traditional storeroom, receipt, storage and issuance procedures are abbreviated. Storage, except for brief periods directly on the plant floor is eliminated. Receipt and issuing documentation can be combined. As a result, there is saving in paperwork and, more importantly a savings in inventory investment, storage and handling.
Material Management System
ISSUING AND COSTING OF MATERIALS Material Ledger Card:Perpetual Inventory:In perpetual inventory system, an entry is made each time the inventory is increased or reduced.
Materials ledger cards or stock ledger sheets constitute a subsidiary materials ledger controlled by the materials or inventory accounts in the general ledger. Materials ledger cards commonly show the account number, description or type of material, location, unit measurement, and maximum and minimum quantities to carry.
Material Management System
ISSUING AND COSTING OF MATERIALS
Physical Inventory:The alternative to a perpetual inventory system is the periodic inventory system, whereby purchases are added to the beginning inventory, the ending (remaining) inventory is considered the cost of material issued.Regardless of whether a periodic or a perpetual inventory system is used, periodic physical counts are necessary to discover and eliminate discrepancies between the actual count and the balances on materials ledger cards.These discrepancies may be due to errors in transferring invoice data to the cards, mistakes in costing requisitions, unrecorded invoices or requisitions or spoilage, breakage and theft.

MATERIAL COSTING METHODS The ultimate objective of material management is to produce accurate and meaningful figures of the cost of goods sold for cost accounting.The figures can be used for purpose of control and analysis and are eventually matched against revenue produced in order to determine operating income.The more common methods of costing materials revenue produced in order to determine operating income.
Material Management System
MATERIAL COSTING METHODS The more common methods of costing materials issued and inventories are:•First-In-First-Out (FIFO)•Average Costing•Last-In-First-Out (LIFO)•Other Methods-such as oMarket Price at date issue, or Last purchase price,oStandard Cost
Material Management System
MATERIAL COSTING METHODS First-In-First-Out (FIFO) Method of Costing:The FIFO method is recommended whenever:
•The size and cost of materials units are large,•Materials are easily identified as belonging to a particular purchased lot, and•Not more than how two or three different receipts of the materials are on a materials card at one time.
Material Management System
MATERIAL COSTING METHODS First-In-First-Out (FIFO) Method of Costing:
Material Management System
MATERIAL COSTING METHODS
Average Costing Method:
Issuing materials at an average cost assumes that each batch taken from the storeroom is composed of uniform quantities from each shipment in stock at the date of issue.
Average costing may be used even though the physical withdrawal is in an identifiable order. If materials tend to be made up of numerous small items low in unit cost and especially if prices are subject to frequent change, average costing is advantageous because:
Material Management System
MATERIAL COSTING METHODS Average Costing Method:
•It is realistic costing method to management in analyzing operating results and appraising future production.•It minimizes the effect of unusually high or more stable cost estimates for future work.•It is a practical and less expensive perpetual inventory system.
Material Management System
MATERIAL COSTING METHODS Average Costing Method:
Material Management System
MATERIAL COSTING METHODS Last-In-First-Out (LIFO) Method of Costing:
The last-in-first-out (LIFO) method of costing materials issued is based on the promise that materials units issued should carry the cost of the most recent purchase, although the physical flow may actually be different. The method assumes that the most recent cost (the approximate cost to replace the consumed units) is most significant in matching cost with revenue in the income determination process.
Material Management System
MATERIAL COSTING METHODS Last-In-First-Out (LIFO) Method of Costing:
Material Management System
MATERIAL COSTING METHODS Other Materials Costing Method:Besides LIFO, FIFO & Average Cost methods of costing materials units into work in process, various other methods exist:•Market Price at Date of Issue or Last Purchase Price:•Standard Cost:
Material Management System
MATERIAL COSTING METHODS•Market Price at Date of Issue or Last Purchase Price:Materials precisely standardized and traded on commodity exchanges such as cotton, wheat, copper, or crude oil, are sometimes costed in to production at the quoted price at the date of issue. In effect, this production substitute replacement cost for experienced or consumed cost and has the virtue of changing materials into production at a correct and significant cost.
Material Management System
MATERIAL COSTING METHODS Standard Cost:
This method change issued materials at a predetermined or estimated cost reflecting a normal or is expected future cost. Receipts and issues of materials are recorded in quantities only on the materials ledger cards or in the computer data bank, thereby simplifying the record keeping and reducing clerical or data processing costs.
Material Management System
MATERIAL PLANNING AND CONTROL
An inventory planning and control method should have but one goal that might be expressed in two ways:
•To minimize total cost, or•To maximize profit within specified time and resource allocations.
Material Management System
MATERIAL PLANNING AND CONTROLPlanning Materials Requirements:To plan manufacturing requirements, every stock item or class of items must be analyzed periodically to: •Forecast demand for the next month, quarter, or year.•Determine acquisition lead time.•Plan usage during the lead time.•Establish quantity on hand.•Place units on order.•Determine reserves or safety stock requirements.
Material Management System
MATERIAL PLANNING AND CONTROL
Materials Control:
The control of materials must meet two opposing needs: •Maintenance of an inventory of sufficient size and diversity for efficient operations, and
•Maintenance of a financially favorable inventory.
Material Management System
MATERIAL PLANNING AND CONTROL
Materials Control Objectives: A basic objective of materials control is the ability to place an order at the appropriate time the best source to acquire the proper quantity at the right price and quality. Effective inventory control should: •Provide a supply of required materials and parts for efficient and uninterrupted operations.•Provide ample stock in periods of short supply (seasonal, cyclical, or strike), and anticipate price changes.
Material Management System
MATERIAL PLANNING AND CONTROL•Store materials with a minimum of handling time a cost and protect them from loss by fire, theft elements and damage through handling.•Keep inactive, surplus, and obsolete items to a minimum by systematic reporting of product changes which affect materials and parts.•Assure adequate inventory for prompt delivery to customers.•Maintain the account of capital invested in inventories at a level consist with operating requirements and management’s plans.
Material Management System
MATERIAL PLANNING AND CONTROL•Control Principles:Inventory control systems and techniques should be based on the following principles:•Inventory is created by purchasing:o Materials and parts, ando Additional labor and overhead to process the
materials into finished goods.•Inventory is reduced through sales and spoilage.•Accurate sales and production schedule forecasts are essential for efficient purchasing, handling, and materials investment.
Material Management System
MATERIAL PLANNING AND CONTROL•Control Principles:•Management policies, which attempt to balance size and diversity of inventory, are the greatest factor in determining inventory investment.•Ordering materials is a response to forecasts, scheduling production controls inventory.•Inventory records alone do not achieve inventory control.•Control is comparative and relative, not absolute. It is exercised by people with varying experience and judgment.•Rules and procedures guide these individuals in making evaluations and decisions.

Material Management System
MATERIAL PLANNING AND CONTROL
Material Control Methods:Materials control methods differ primarily in the care and cost expanded. Critical items and high-value items require greater attention than do low-value items.Control methods include the:
• Order cycling, •The min-max, and•Just-in-time
Material Management System
MATERIAL PLANNING AND CONTROLOrder Cycling Method or Cycling Review Method:
This method examines periodically (e.g. each 30, 60, or 90 days) the status of quantities on hand of each item or class.Different companies use different time periods between reviews and may use different cycles for different types of materials. High value items and that would tie up normal operations if out of stock usually require a short review cycle. On low-cost and non critical items, a longer review cycle is common, since these materials would be ordered in large quantities and stock out would not be as costly.
Material Management System
MATERIAL PLANNING AND CONTROL
Min-Max Materials:
This method is based on time premise that the quantities of most stock items are subject to definable limits. A maximum quantity for each item is established. A minimum level provides the margin of safety necessary to prevent stock outs during a recorder cycle. The minimum level sets the order point, and the quantity to order will usually bring inventory to the maximum level.
Material Management System
MATERIAL PLANNING AND CONTROL
Just-in-Time Materials Control:
The saving that can result from a minimum inventory investment and associated carrying costs has led to increasing attention to a just-in-time (JIT) system. Such a procedure calls for heightened coordination with suppliers so that materials arrive immediately prior to their use.Japanese industry is credited with pioneering this procedure that is now being used by some U.S. manufacturers. For example, General Motors has implemented this approach, with a fully automated JIT parts inventory system.
Material Management System
MATERIAL PLANNING AND CONTROL
Selective Control:The ABC Plan:Segregation of materials for selective control called the ABC plan is an analytical approach based upon statistical averages. The ABC Plan, measures the cost significance of each materials item.•A” or High Value, items would be under the tightest control and the responsibility of the most experienced personnel•“B” or Medium-Value, items would under the less strict control as compare to A.•“C” or Low-Value, items would be under simple physical controls, such as the bin-system with safety stocks.

CONTROLLING MATERIALS IN PROCESS
Work in process inventory investment is largely determined by the time necessary for goods to pass through the production process. The time involved includes: •Set up time-preparing to run a job on a machine.•Running time-actually performing the work.•Queue Time- the amount of time that the job spends waiting to be worked on.•Move time-transporting the goods to the next processing location.•Wait time-time spent waiting to be moved.
Material Management System
CONTROLLING MATERIALS IN PROCESSControlling Finished Goods:An accurate sales forecast is the key to effectively managing finished goods inventories and meeting delivery dates. This forecast must be communicated to production control departments in order to develop production schedules for meeting sales commitments.To meet customer performances and competition, many product lines feature a growing array of colors, sizes, and optional equipment. This results in added finished goods inventory items and more work in process inventory. The need for tighter control becomes increasingly important.
Material Management System
CONTROLLING MATERIALS IN PROCESS
Control of Obsolete and Surplus Inventory:Almost every organization is faced with the problem of surplus and obsolete inventory at one time or other. Whatever the many possible reasons for such conditions, some action is required in order to reduce or eliminate these items from inventory and free the related capital. To accomplish a reduction, management should first make certain that the buildup will not continue due to present ordering policies, and should then take steps to dispose of stock.
Material Management System
CONTROLLING MATERIALS IN PROCESS
Control of Obsolete and Surplus Inventory:
Accurate perpetual inventory records showing acquisitions and issue quantities and dates, as well as periodic review of the records, are necessary to identify obsolete and surplus items. Obsolete inventory usually results from changing a design or dropping a product. Prompt sale of the inventory for the first reasonable offer in often the best policy..

Reporting on Inventory Control:
Management requires timely information concerning inventory control efforts. This information should be reported in a concise, easily understood form.Quantitative as well as graphic comparisons of actual and budgeted inventory use to report inventory trend within the organization.

THE IMPACT OF MODERNIZER FACTORY PROCESSES ON MATERIAL MANAGEMENTIn inventory numbers, factories are moving from manufacturing processes involving manual and / or fixed automated systems. The shift is toward flexible manufacturing system, which consist of an integrated collection of automated production processes, automated materials movement, and computerized system controls to utilize the facilities in the efficient manufacture of a highly flexible variety of products. The extent of product variety is constrained by the need for the products to share certain broad characteristics that allow grouping within a particular family of products while maintaining considerable flexibility.

EDP (Electronic Data Processing) For Material Management:
The preceding descriptions of invoice approval and payment were for manual operations performed by an accounts payable clerk or an invoice clerk. In an electronic data processing (EDP) system, the computer-to a great extent-replaces the clerk. Upon receipt of the invoice (the source document), the accounts payable clerk enters the account distribution on the invoice. The data are then directly inputted from the invoice to the computer data bank via a terminal device. The data are edited, audited, and merged with the purchase order and the receiving order data, both of which have been stored in the computer data bank.
Material Management System
EDP (Electronic Data Processing) For Material Management:
The common matching criterion on all documents is the purchase as all documents is the purchase order number. Quantities, monetary values (amounts), due dates, terms and unit prices are matched. When in agreement, the cost data are entered in the accounts payable computer file with a date for later payment, or a printout of a check is transmitted for payment. Listings in journal form can be produced as needed.
Material Management System
EDP (Electronic Data Processing) For Material Management:
The above proceed are deals with the accounts payable phase of a purchase transaction of equal importance is the need for posting the data in quantities and amounts to the materials inventory file in the EDP system. The information enters the EDP system from either the invoice or the invoice or the invoice approval from, which would have to include all computer necessary data. The internal computer program updates the materials inventory file. The withdrawal of materials could also be computerized, so that manual postings to the materials inventory file, as well as other manual operations, would be eliminated.
