Inventory management is the process of tracking and controlling inventory throughout its lifecycle—from raw materials to finished products. It ensures businesses maintain optimal stock levels, reduce costs, and meet customer demand efficiently.
What is Inventory?
Inventory includes anything a business must stock or restock, categorized into four main types:
Raw Materials & Components: Ingredients or parts used in production.
Work-in-Progress (WIP): Items currently being processed.
Finished Goods: Ready-for-sale products.
Maintenance, Repair & Operating (MRO) Supplies: Support materials like tools and lubricants.
Importance of Inventory Management
Balancing supply and demand is key. Poor inventory control can lead to excess stock, increased costs, and waste, or shortages that disrupt operations and sales. Effective management helps businesses:
Reduce storage and spoilage costs
Prevent stockouts and lost sales
Optimize cash flow
Improve efficiency and customer satisfaction
Steps in Inventory Management
Planning & Ordering: Forecast demand and order materials accordingly.
Receiving & Storing: Catalog inventory and organize storage.
Selling & Fulfilling Orders: Process and ship orders efficiently.
Auditing & Reporting: Maintain accurate records and track inventory movement.
Reordering: Use data to restock based on demand and supply chain conditions.
Inventory Management Methods
Different techniques suit different businesses:
ABC Analysis: Prioritizes high-value items.
Just-in-Time (JIT): Orders inventory only as needed.
Safety Stock: Keeps extra inventory as a precaution.
Economic Order Quantity (EOQ): Optimizes order quantities.

Industry Applications
