Q & A

What is inventory management?

Inventory management refers to the process of overseeing and controlling the flow of goods, materials, and resources within an organization. It ensures that the right amount of inventory is available at the right time, preventing shortages or excess stock, which can affect production efficiency and costs.

What are the main types of inventory in manufacturing?

The main types of inventory in manufacturing are: raw materials, work-in-progress (WIP), finished goods, and supplies. These inventories are essential for production processes, ensuring that all necessary components are available when needed.

Why is inventory management critical in manufacturing?

Inventory management is critical in manufacturing because it ensures the continuous availability of materials needed for production without causing delays. It helps optimize production schedules, minimize costs, and maintain a steady supply chain, thus preventing disruptions.

What are the factors that influence inventory management?

Factors influencing inventory management include the predicted usage of raw materials, material costs, storage costs, purchase policies, lead times, replenishment models, and safety stock requirements. These factors help determine when and how much inventory to reorder.

What are the objectives of inventory management?

The objectives of inventory management are to ensure smooth operations, meet customer demand, reduce costs, avoid overstocking or stockouts, and provide flexibility in production scheduling. Proper inventory management minimizes operational risks and supports effective decision-making.

What are the advantages of holding inventory?

Advantages of holding inventory include ensuring continuous operations, preventing stockouts, offering flexibility in production scheduling, mitigating risks related to supply chain disruptions, and enabling bulk purchasing discounts to reduce overall costs.

What are the disadvantages of holding large amounts of inventory?

Disadvantages of holding large amounts of inventory include high storage costs, increased risk of obsolescence or damage, reduced cash flow due to investment in unsold goods, and higher chances of inventory wastage if demand fluctuates unexpectedly.

What is the Economic Order Quantity (EOQ) method?

The Economic Order Quantity (EOQ) method is a formula used to determine the optimal order quantity that minimizes the total cost of inventory, including storage and ordering costs. It helps businesses decide the most cost-effective amount of inventory to order at a time.

What is the Just-in-Time (JIT) inventory management method?

The Just-in-Time (JIT) inventory management method focuses on ordering and receiving goods only when they are needed in the production process. This method reduces storage costs and minimizes excess inventory, leading to more efficient and lean production processes.

What is the ABC analysis in inventory management?

ABC analysis is a method of categorizing inventory items based on their value and usage frequency. It divides inventory into three categories: A (high-value, low-quantity items), B (medium-value, medium-quantity items), and C (low-value, high-quantity items). This helps prioritize inventory control efforts and resources.
