or even thousands of items in inventory, ranging from small things such as pencils, paper clips, screws, nuts, and bolts to large items such as machines, trucks, construction equipment, and airplanes. Naturally, many of the items a firm carries in inventory relate to the kind of business it engages in and are essential to the conduct of that business. Therefore, effective inventory management is important for the successful operation of most firms and their supply chains. Poor inventory management can hamper operations, diminish customer satisfaction, and increase operating costs. Effective inventory management can help keep operations running smoothly and efficiently, and contribute to customer satisfaction.
