Steps in Materials Control

Materials Control is a vital aspect of production management that ensures efficient and effective use of materials throughout manufacturing processes. It helps organizations maintain cost-effectiveness, enhance product quality, and optimize inventory levels. The steps involved in materials control are designed to streamline operations, minimize waste, and improve overall efficiency.

• Setting Standards and Specifications:

Before purchasing any materials, it’s crucial to define clear and precise standards and specifications. These standards ensure that only materials that meet specific quality and performance criteria are used in production. This step involves detailed descriptions of material types, grades, dimensions, and performance characteristics. Standards help in maintaining consistency in the quality of finished products and reduce variability in production processes.

• Supplier Selection and Purchase Planning:

Choosing the right suppliers is fundamental to effective materials control. Supplier selection involves evaluating potential suppliers based on criteria such as price, quality, reliability, and service delivery. Purchase planning, on the other hand, requires coordination between the procurement department and production planning to forecast material needs accurately. This planning helps in determining when and how much material to order, considering lead times and production schedules to avoid shortages or excessive inventory.

• Purchase Requisition:

Purchase requisition is an internal document sent from one department (usually production) to the purchasing department. It formally requests the procurement of specified materials needed for production. This document should list the types and quantities of materials, expected delivery dates, and possibly preferred suppliers. This step ensures that purchases are authorized and needed, helping to control expenditures and maintain budget discipline.

• Purchase Ordering:

Upon receiving a purchase requisition, the purchasing department issues a purchase order to the supplier. This order includes detailed information about the materials required, quantities, prices agreed upon, delivery schedule, and terms and conditions of purchase. The purchase order serves as a legally binding agreement between the buyer and the supplier, ensuring that suppliers meet the specified requirements.

• Receiving and Inspection:

When materials are delivered, they must be checked to ensure they match the purchase order in terms of quantity and specifications. This is a critical control point to prevent errors, defects, and substandard materials from entering the production process. Inspection might involve visual checks, measurements, or more detailed tests depending on the nature of the materials and the criticality of their function in the product.

• Storage and Inventory Control:

Proper storage conditions are essential to preserve material quality and ensure safety. Materials need to be stored in a way that prevents damage, contamination, and deterioration. Inventory control techniques such as FIFO (First-In, First-Out) or LIFO (Last-In, First-Out) are applied to manage how materials are used in production. These methods help in managing stock levels effectively, reducing the cost of holding inventory, and ensuring that older stock is used before it expires or becomes obsolete.

• Issue of Materials:

Materials should be issued to the production floor as per the production requirements and only against authorized material requisitions. This step ensures that materials are used appropriately and reduces wastage. The issue of materials should be recorded to maintain traceability and accountability, helping in precise cost allocation and inventory management.

• Record Keeping and Reporting:

Accurate and up-to-date records of all material transactions are vital for effective materials control. These records include details of purchases, receipts, issues, returns, and stock levels. Regular reports based on these records help managers make informed decisions regarding material management, identify trends, assess supplier performance, and monitor compliance with policies.

• Stock Taking and Reconciliation:

Periodic physical stock taking is essential to verify the accuracy of inventory records. This process involves counting all physical stock and reconciling it with inventory records. Discrepancies must be investigated and corrected. This step helps in maintaining the integrity of financial records and provides assurance that inventory losses due to theft, damage, or mismanagement are minimized.

• Performance Review and Continuous Improvement:

Regular evaluation of the materials control process helps identify areas for improvement. Performance review might focus on supplier reliability, the efficiency of inventory management practices, or the effectiveness of internal controls. Based on these reviews, processes can be adjusted to enhance efficiency, reduce costs, and improve overall performance.
