Human Resources Management:** Managing the workforce effectively, including scheduling, training, and ensuring employee productivity and satisfaction. **11. Maintenance and Reliability Management:** Ensuring that equipment and facilities are maintained properly to minimize downtime and disruptions in production. **Historical Development of Operations Management** **Ancient Times --** although "operations management" existed years after this era, they laid the foundation for the principles and techniques that have evolved over centuries. **Pre-industrial Revolution** **1.Craft Production --** craftsmen or highly skilled workers directed apprentices in performing hand work on products with the use of simple, flexible tools to produce small quantities of customised goods. **Industrial Revolution --** was the transition from creating goods by hand to using machines (17th to Early 19th Century). **Steam engines** play a vital role in improving the transportation of goods and raw materials as well as providing a source of power to operate machines in factories. Ample of supplies coal and iron are used in generating power to those machines. **2. Division of Labor by Adam Smith --** which broke production of goods into small, specialised tasks that were assigned to workers on production lines. **3. Factory System**(mid 1800's) **--** refers to the development of centralised factories or mills that produce goods on a mass scale. Inventors developed machines and techniques that helped the industry, especially the textile industry. **Scientific Management** (Late 19th to Early 20th Century) **4. Frederick Winslow Taylor** is the father of scientific management, theory of management that analyses and synthesises workflows. He introduced these principles to improve work methods by planning, selecting, providing tools, training workers, and providing incentives for good performance. **5. Henry Ford --** he employed scientific management in his car factory production line that led to mass production and lowered costs. His revolutionary innovation is a vehicle called Model T. (1908 Model T) These are things he implemented in the factory: \- Mass production -- system of production in which large volumes of standardised goods are produced by low-skilled or semi-skilled workers using highly specialised, and often costly, equipment \- Interchangeable parts -- parts of a product made to such precision that they do not have to be custom fitted. Introduced by Eli Whitney and Ford uses it for his production line. \- Division of Labor -- the breaking up of the production process into small tasks, so that each worker performs a small portion of the overall job. **Human Relations Movement** (early 20th Century) -- a theory emphasised on the importance of the human element such as employee morale and motivation in the workplace. In short, it is the application of behavioural sciences to management theories. **World War II and Post-War Era** **6. Operations Research (OR)** Operations research, born out of the military's need for logistics and optimization during World War II, became a key component of operations management. OR uses mathematical models to solve complex decision-making problems. **7. Total Quality Management (TQM)** Post-war Japan introduced Total Quality Management, emphasizing quality control and continuous improvement. Figures like W. Edwards Deming and Joseph M. Juran played a pivotal role in its development. **Late 20th Century** **8. Lean Manufacturing** The concept of Lean Manufacturing, derived from the Toyota Production System (TPS), emerged in the late 20th century. It focuses on minimizing waste, optimizing processes, and improving efficiency. **9. Computerization and Technology** The widespread adoption of computers and information technology revolutionized operations management. It led to automation, improved data analysis, and enhanced supply chain management. **21st Century** **10. Supply Chain Management (SCM)** Supply chain management gained prominence in the 21st century, emphasizing the end-to-end management of the flow of goods, information, and finances across the entire supply chain. **11. Sustainability and Environmental Concerns** The 21st century saw a growing emphasis on sustainable operations management, addressing environmental and social responsibilities, as well as resource optimization. **Future Trends** **12. Industry 4.0** Industry 4.0, characterized by the integration of digital technologies, artificial intelligence, and the Internet of Things (IoT), is shaping the future of operations management. It promises increased automation, connectivity, and data-driven decision-making. **Strategic Role of Operations in Organizations** **1. Cost Leadership** This involves aiming to have the lowest costs or to be the most price-competitive in the market. It focuses on high volume of output as cheaply as possible, and suits mass production. One aspect of cost leadership arises from a business creating economies of scale. **2. Goods/Service Differentiation** This focuses on more costly operations due to design, innovations and features that make the good or service different. Product differentiation distinguishes products in some way from its competitors. **3. Technology** is the design, construction and/or application of innovative devices, methods and machinery upon operations processes. It plays an important role in operations management from administration, through to all operations processes. **4. Quality Expectation** are a specific reference to how well designed, made and functional goods are, and the degree of competence with which services are organised and delivered. Managing quality expectations in both the manufacturing of products and the delivery of services is an essential role and goal of operations management. **5. Cost-based Competition** is derived from determining break even point and then applying strategies to create cost advantages over competitors. In highly competitive markets, it can shape the operations function in competing businesses. **Competitive Advantages through Operations** **1. Cost Leadership** Operational Efficiency Economies of Scale Supplier Relationship **2. Quality and Reliability** Quality Control Consistent Delivery Product Differentiation **3.
