Regardless of the type of operation being managed, chances are that a company needs to keep supplies on hand that allows operations management to occur. Inventory is the amount and number of raw materials, parts, and finished products that an organization has in its possession at any given time. Four kinds of inventory are kept by companies: raw materials, component parts, work-in-process inventories, and finished goods. Uncontrolled inventory can lead to huge costs for a company, so managers need to measure their inventory well to prevent inventory costs from becoming too large. Managers have a lot of responsibilities: leading people, serving customers, maintaining internal controls, satisfying stakeholders, and driving profitability.Throughout all these responsibilities, managers must always strive to manage worker productivity and product quality. This course discusses how inventory is managed towards these ends.
