- 3. What is Operations Management? • Operations management is the management of processes that transform inputs into goods and services that add value for the customer. • It is a process of planning, organizing, and supervising the operations of the business for better productivity. • Operations management focuses on activities like managing inventory, capacity planning, production & process, supply chain management, packaging, distribution, warehousing etc. • All factories, manufacturing plants, construction, agriculture & even service sectors follow the basic principles of operations management. • Operation management aims at reducing the cost to business by avoiding any wastage of resources.
- 5. Nature of OM • Focuses on the management of resources and processes to create and deliver goods or services. • Concerned with all aspects of an organisation’s operations, including the design, planning, control, and execution of processes. • Its key components include production planning, inventory management, quality control, supply chain management, and process optimization.
- 6. Importance of OM • The importance of operations management lies in its ability to drive e ffi ciency, quality, and competitiveness within an organization. • E ff ective operations management can lead to cost reduction, improved customer satisfaction, faster delivery times, and enhanced fl exibility to adapt to market demands.
- 7. Historical Development of OM • Operations management as a distinct fi eld emerged during the Industrial Revolution in the late 18th century when factories started employing mass production methods. • However, its formal development can be traced back to the early 20th century.
- 8. Key Milestones in Development • Scienti fi c Management (late 19th - early 20th century): Pioneered by Frederick W. Taylor, this approach focused on optimizing individual tasks and work processesto improve e ffi ciency. • Human Relations Movement (1920s - 1930s): Elton Mayo and others emphasized the importance of human factors and employee motivation in enhancing productivity. • Total Quality Management (TQM) (1950s - 1960s): Focused on quality improvement across all aspects of an organization, not just production. • Lean Thinking (1990s): Inspired by the Toyota Production System, Lean emphasizes eliminating waste and continuous improvement. • Six Sigma (1980s - 1990s): A data-driven methodology aiming to reduce defects and variations in processes.
- 9. Transformation Processes in OM • The transformation process is a fundamental concept in operations management, describing how inputs are converted into outputs. • It involves the following stages: Input Transformation Output Feedback
- 10. Transformat ion Processes in OM 1. Input • This stage involves gathering and assembling all the necessary resources to start the production process. • Inputs include raw materials, labor, equipment, technology, and information.
- 11. Transformation Processes in OM 2. Transformation • During this stage, inputs are processed or transformed into the fi nal output, which could be goods or services. • Transformation methods can vary widely depending on the industry and the nature of the product or service.
- 12. Transformation Processes in OM 3. Output • The output represents the end result of the transformation process. • For manufacturing companies, the output is typically a tangible product, while service-based organizations produce intangible outputs like experiences, advice, or knowledge.
- 13. Transformation Processes in OM 4. Feedback • This stage involves obtaining data and feedback about the output and, if necessary, making adjustments to improve the process and overall performance.
- 14. Differences b/w Services and Goods Nature Goods Services Intangibility Goods are tangible products that can be seen, touched, and physically possessed. They have a physical form and can be stored, inventoried, and transported. Services, on the other hand, are intangible. They cannot be seen or touched and do not have a physical presence. Services are experienced or consumed at the time they are produced and cannot be stored or inventoried. Production and Consumption Goods are typically produced fi rst and then consumed later. They can be produced in advance and stored for future consumption. Services are produced and consumed simultaneously. They are created and delivered in real-time, directly to the customer. Heterogeneity Goods are usually standardized and have consistent quality and features. A unit of a particular good is generally identical to another unit of the same good. Services are often heterogeneous, meaning they can vary in quality and delivery from one provider to another or even from one interaction to another with the same provider. Perishability Goods are generally not perishable. They can be stored for an extended period without losing their value or quality. Services are perishable. If not consumed at the time of production, they are lost, and their value cannot be stored for future use.
- 15. Differences b/w Services and Goods Nature Goods Services Customer Participation Customer involvement in the production of goods is usually minimal. The customer may be involved in the selection and purchase of the product, but the actual production occurs independently. In many service processes, customer participation is essential. Customers often actively participate in the co-creation of the service experience, in fl uencing the outcome. Ownership and Transfer Goods are typically owned by the customer after purchase. The customer can transfer ownership to another party through sale or gift. Services are experienced and utilized but not owned by the customer. They cannot be transferred to another party. Evaluation of Quality The quality of goods can often be evaluated before purchase through inspection, testing, or reviews. The quality of services is often evaluated based on the customer's experience after they have been delivered. This evaluation may be subjective and in fl uenced by individual perceptions.
