Materials Management

Materials management is a management discipline that encompasses the planning, procurement, storage, control, and distribution of raw materials, components, and other materials required by an organization or enterprise. Its primary objective is to enhance operational efficiency and reduce costs by ensuring that the right materials are available in the right quantity, at the right time, in the right place, and with the right quality. As an essential component of supply chain management, materials management is also referred to by terms such as asset management, equipment management, and material handling. This process is a fundamental element that manages cost, value flow, and cash flow across all stages from design to product delivery to the customer. It holds critical importance for industries such as manufacturing, construction, healthcare services, textiles, pharmaceuticals, oil, and natural gas, which involve the movement of numerous raw materials.

Core Processes of Materials Management

Materials management is an integrated set of processes covering all steps from procurement to utilization of materials. These processes directly impact an organization’s efficiency and profitability.

Materials Requirements Planning (MRP)

Materials Requirements Planning (MRP) is a scheduling and control technique at the heart of a company’s logistics chain. Its primary purpose is to determine the quantity and timing of materials to be produced or ordered by working backward from the delivery date of the finished product. This minimizes inventory investment, increases production efficiency, and improves customer service. For an MRP system to function correctly, it requires up-to-date data such as the master production schedule, product structures (bill of materials), lead times for raw materials and work-in-process, and current inventory levels.

MRP can also employ statistical forecasting models such as arithmetic averages, linear regression analysis, and seasonal indexing to predict future requirements.

Purchasing

The purchasing process begins with fulfilling the needs identified by MRP. This stage involves identifying potential suppliers, issuing requests for quotations, evaluating received bids, and placing orders with the supplier offering the most favorable price and terms. Modern workflow-based systems can optimize this process by automating functions such as vendor evaluation. Procuring the correct quantity of materials ensures that necessary inputs are available for end-user operations while minimizing capital tied up in storage and inventory.

Receiving and Storage

This is the process of accepting materials delivered by suppliers into the organization. During receiving, incoming products are verified for compliance with purchase orders, quality control tests are conducted, and inventory records are updated. Storage involves the safe and orderly preservation of materials until their next use or movement. Storage acts as a buffer between production and consumption, mitigating the impact of potential material shortages or production errors. Traceability is maintained through various storage strategies such as FIFO (First In First Out), LIFO (Last In First Out), and location-based systems. Specific rules, such as segregating hazardous materials or storing perishable goods in cold storage, are also managed within this process.

Inventory Management

Inventory management aims to control inventory costs by maintaining accurate records of materials used to sustain organizational operations. In this process, ideal minimum and maximum levels are established for each inventory item. These levels are dynamically monitored, and when stock falls below the minimum threshold, the system can automatically generate alerts or purchase orders. Features such as lot, batch, or serial number tracking enable backward traceability. Effective inventory management increases inventory accuracy, prevents material loss, and reduces capital costs.

Material Handling and Transportation

This is the physical movement of materials within a warehouse or between production lines. Ensuring that the correct materials are delivered to manufacturers or relevant units on time is such a complex task in large organizations that dedicated departments are often established for this function. Optimization of material transportation is achieved through selecting appropriate warehouse locations, using efficient transport methods, and incorporating material dimensions (area, volume, etc.) into logistics planning. This optimization results in a more consistent raw material flow for manufacturers and lower logistics costs.

Types and Classification of Materials

Materials management requires the effective handling of various types of materials with different characteristics. This classification enables standardization of processes and accurate data analysis.

Direct and Indirect Materials: Materials are generally divided into two main categories. Direct materials are fundamental components that form part of the final product and typically carry the highest cost. Indirect materials are lower-cost items necessary for production but not part of the final product, such as gloves, maintenance supplies, and other consumables.

Material Classes and Hierarchy: Organizations classify their materials into categories such as finished goods, work-in-process, raw materials, subcontracted materials, consumables, packaging materials, commercial goods, and spare parts. This classification assigns digital identities to materials, facilitating tracking. Intelligent coding systems support this hierarchy by generating standardized and error-free stock codes based on predefined criteria.

Variation Management: Particularly in sectors such as apparel and footwear, variation management is used for materials with identical technical specifications but differing attributes such as color or size. This approach eliminates the need to create separate material codes for each variation, preventing unnecessary code clutter and simplifying data management.

Benefits and Objectives of Materials Management

An effectively implemented materials management system provides organizations with significant competitive advantages. Its primary benefits include:

• Cost Savings: Reduces inventory costs, prevents waste, and lowers overall expenses by optimizing procurement processes.
• Increased Efficiency: Enhances operational efficiency by improving material flow and ensuring that required materials are always available for production.
• Reduction of Waste: Minimizes losses caused by incorrect orders and products past their expiration dates.
• Inventory Accuracy: Real-time and accurate inventory data supports better production planning and prevents stock losses.
• Just-in-Time (JIT) Management: Enables the implementation of inventory management methods like JIT, which deliver materials exactly when needed. This reduces the quantity of inventory held and associated risks.
• Customer Satisfaction: Ensures uninterrupted production processes, leading to timely order fulfillment and higher customer satisfaction.

The Role of Technology: ERP and Automation

Modern materials management is closely integrated with Enterprise Resource Planning (ERP) systems. The Materials Management (MM) module is one of the core components of many ERP systems such as SAP. These modules consolidate all processes—including materials requirements planning, purchasing, inventory management, and invoice verification—into a single platform.

ERP systems improve decision-making by ensuring all departments have access to the same up-to-date data. Automation technologies such as barcode applications and handheld terminals enable fast, accurate, and real-time recording of warehouse movements (receiving, goods issue, counting, etc.). These technologies reduce operational errors, guide users, prevent losses, and enhance efficiency.

Materials Management in Different Industries

While the fundamental principles of materials management are universal, their applications vary by industry.

Manufacturing: It lies at the heart of production processes. Uninterrupted flow of raw materials is vital for the efficiency of production lines.

Construction: Materials constitute one of the largest cost items in projects. Delivering the correct quantity and quality of materials to the site at the right time is critical for completing projects on schedule and within budget.

Fleet Management: It includes inventory tracking of materials such as HGS/OGS tags, chains, spare parts, lubricants, and tires to ensure vehicles remain operational. The primary focus in this area is monitoring the cost of these materials and controlling vehicle assignments.

Healthcare Services and Pharmaceuticals: It manages sensitive processes such as expiration date tracking and lot control for sterile materials, medications, and medical devices. This is of great importance for patient safety and compliance with regulatory requirements.
