Summary of Global Supply Chain and Operations Management

## Introduction Industrial production and operations management focus on how goods are made, where they are made, and how resources are organized to meet customer demand reliably and efficiently. This material breaks down core concepts such as capacity, plant location, inventory, supply chains, outsourcing, and economies of scale into clear explanations, practical examples, and short activities to help a self-study (Not attending) learner master the subject. ## Key Concepts and Definitions > **Capacity:** the (maximum) rate of output a plant or production process can achieve. > **Plant:** a collective word for all the buildings, machines, equipment, and other facilities used in the production process. > **Inventory (stock):** a company’s reserves of raw materials, parts, work-in-process, and finished products. > **Component:** any of the pieces or parts that make up a product or machine. > **Location:** the geographical situation of a factory or other facility. > **Supply chain:** a network of organizations involved in producing and delivering goods or a service. > **Outsourcing:** buying products or processed materials from other companies rather than manufacturing them yourself. > **Economies of scale:** cost savings that arise from large-scale production. > **Lead time:** the time needed to perform an activity, such as manufacturing a product or delivering it to a customer. ## Breaking Down Capacity Decisions ### What managers decide - Where to produce (location) and what capacity each site should have - How much inventory to hold to smooth production and meet demand ### Consequences of insufficient capacity (shortage) - Lost sales and market share that are often permanent - Long lead times that allow competitors to enter the market - Customers switching to other suppliers if lead time increases - You may be forced to produce additional, less profitable products Practical example: A toy maker with insufficient capacity before holiday season may miss sales, and buyers who switch brands may not return next year. ### Consequences of excess capacity (overcapacity) - Under-utilized workforce and equipment leading to wasted fixed costs - Worsening working environment and potential industrial relations problems if work is not steady Practical example: A factory built for projected demand that never materializes still pays depreciation, utilities, and salaries. ## Facility Size: Advantages vs Disadvantages | Topic | Advantages | Disadvantages | |---|---:|---| | Large facilities | Economies of scale: lower average fixed cost per unit; ability to run longer production runs and fewer set-ups; lower unit cost | Finding enough workers; coordinating material flows becomes difficult; larger plants can degrade working environment | | Small facilities | Greater flexibility; easier to manage workers and flows; often closer to niche markets | Higher average cost per unit; less purchasing power for quantity discounts | Fun fact: Large factories were a key driver of cost reductions during the Industrial Revolution because they allowed specialization of labor and machinery. ## Inventory: Why hold it and the trade-offs ### Advantages of holding large inventory - Meet variation in product demand quickly - Protection against variation in raw material delivery times (shortages, strikes, incorrect shipments) - Ability to take advantage of quantity discounts in purchasing ### Disadvantages of holding large inventory - Costs of storage, handling, insurance, depreciation, and the opportunity cost of capital - Risk of obsolescence, theft, breakage - Longer lead times can let competitors enter the market if inventory is not responsive Practical example: A retailer with high inventory for a seasonal product may pay high storage costs and risk obsolescence once the season ends. ## Matching vocabulary to definitions (practice) 1 Inventory (stock) — a company’s reserves of raw materials, parts, work-in-process, and finished products. 2 Com
