Operations Management • Operations Management refers to the direction and control of the process that transform inputs into products and services. • Operations management (OM) is defined as the design, operation, and improvement of the systems that create and deliver the firm’s primary products and services. Why Study Operations Management? Systematic Approach to Org. Processes Business Education Operations Management Cross-Functional Applications Career Opportunities Reasons for Studying Operations Management • A business education is incomplete without an understanding of modern approaches to managing operations. Every organization produces some product or service so students must be exposed to modern approaches for doing this effectively. • Operations management provides a systematic way of looking at organizational process. Operations management uses analytical thinking to deal with real-world problems. It sharpness our understanding of the world around us. Reasons for Studying Operations Management • Operations management presents interesting career opportunities. These can be in direct supervision of operations or in staff position in operations management specialties such as supply chain management and quality assurance. • The concepts and tools of operations management are widely used in managing other functions of a business. All managers have to plan work, control quality, and ensure productivity of individuals under their supervision. How is operations relevant to my major? • Accounting • Information Technology • Management • “As an auditor you must understand the fundamentals of operations management.” • “IT is a tool, and there’s no better place to apply it than in operations.” • “We use so many things you learn in an operations class— scheduling, lean production, theory of constraints, and tons of quality tools.” How is operations relevant to my major? • Economics • Marketing • Finance • “It’s all about processes. I live by flowcharts and Pareto analysis.” • “How can you do a good job marketing a product if you’re unsure of its quality or delivery status?” • “Most of our capital budgeting requests are from operations, and most of our cost savings, too.” OM Across the Organization • Most businesses are supported by the functions of operations, marketing, and finance • The major functional areas must interact to achieve the organization goals • Marketing is not fully capable of meeting customer needs if they do not understand what operations can produce • Human resources must understand job requirements and worker skills OM Across the Organization • Finance cannot judge the need for capital investments if they do not understand operations concepts and needs. • Information systems enables the information flow throughout the organization. • Accounting needs to consider inventory management, capacity information, and labor standards.

Operations managers make process decisions about the types of work to be done in house, the amount of automation to use, and methods of improving existing systems. Types of OM Decisions • Part 3 : Quality : Quality issues underlie all process and work activity. Operations managers help establish quality objectives and seek ways to improve the quality of the firm’s products and services. • Part 4 : Capacity, Location, Layout: The types of decisions in this category often require long-term commitments. Operation managers help determine the system’s capacity (Capacity); the location of news facilities including global operations (Location); and the organization of departments and a facility’s physical layout (Layout) Types of OM Decisions • Part 5: Operating Decision: Operations manager help to coordinate the various parts of the internal and external supply chain (Supply-Chain Management), forecast demand (Forecasting), manage inventory (Inventory Management), and control output and staffing levels over time (Aggregate Planning).

These are Growth of the service sector Productivity Changes Global Competitiveness Quality, time and technological change Environmental, ethical and diversity issues Trends in OM • Service sector growth: The service sector of the economy is significant. Services may be divided into three main groups. These are Government Wholesale and retail sales Other services (transportation, utilities, communication, health etc) public The share of the workforce in service jobs is well above 60 percent in Britain, Canada, France and Japan. Trends in OM • Service sector growing to 50-80% of non-farm jobsSee Global competitiveness • Demands for higher quality • Huge technology changes • Time based competition • Work force diversity Trends in OM • Productivity Changes: Productivity is the value of outputs (goods and services) produced divided by the value of input resources (wages, costs of equipment and the like) used. The value of output can be measured by what the customer pays or simply by the number of units produced or customers served. The value of inputs can be measured by their costs or simply by the number of hours worked. Trends in OM • Global Competitiveness: Strong global competition affects industries everywhere. Most products today are global composites of material and services from throughout the world. Polo Shirt is sewn in Hondurus from cloth cut in the United states. Trends in OM • Competition based on quality, time and technology: Another important trend is that more firms are competing on the basis of time; filling orders earlier than the competitors, introducing new products and services quickly, and reaching the market first. Another increasing important factor in operations management is accelerating technological change. Trends in OM • Ethical, workforce diversity and environmental issues: Business face more ethical quandaries than ever before, intensified by an increasing global presence and global technological change. Environment issues, such as toxic wastes, poisoned drinking water, poverty, air quality and global warming are getting more emphasis. Today’s OM Environment • Customers demand better quality, greater speed, and lower costs • Companies implementing lean systems concepts – a total systems approach to efficient operations • Recognized need to better manage information using ERP and CRM systems • Increased cross-functional decision making Achieving Cross-Functional Coordination • A unified strategy should be developed by management as a starting point, giving each department a vision of what it must do to help fulfill the overall organizational strategy. • The organizational structure and management hierarchy can be redesigned to promote crossfunctional coordination. Achieving Cross-Functional Coordination • The goal-setting process and reward systems can encourage crossfunctional coordination. • Improvements to information systems also can boost coordination. Information must in part be tailored to the needs of each functional manger. Achieving Cross-Functional Coordination • Informal social systems are another device that can be used to encourage better understanding across functional lines. • Employee selection and promotion also can help foster more crossfunctional coordination by encouraging broad perspective and common goals. Productivity Productivity is a common measure on how well resources are being used. In the broadest sense, it can be defined as the following ratio: Outputs Inputs Factors Affecting Productivity Capital Quality Technology Management Measures of Productivity • Partial measures – output/(single input) • Multi-factor measures – output/(multiple inputs) • Total measure – output/(total inputs) Total Measure Productivity Total Measure Productivity = Outputs Inputs or = Goods and services produced All resources used Partial Measure Productivity • Partial measures of productivity = • Output or Output or Output or Output Labor Capital Materials Energy Multifactor Measure Productivity • Multifactor measures of productivity = • Output Labor + Capital . + Energy or • Output Labor + Capital . + Materials Productivity Calculate the productivity following operation. for the • Three employees process 600 insurance policies in a week. They work 8 hours per day, 5 days per week. • A team of workers make 400 units, which is valued by its standard cost of Tk.10 each (before markups for other expenses and profit). The accounting department reports that for this job the actual costs are Tk.400 for labor, Tk.1000 for materials, and Tk.300 for overhead. Productivity Policies processed Labor productivity = Employee hours 600 policies Labor productivity = (3 employees)(40 hours/employee) Labor productivity = 5 policies/hour Productivity Labor productivity = 5 policies/hour Multifactor productivity = Quantity at standard cost Labor cost + Materials cost + Overhead cost Productivity Labor productivity = 5 policies/hour Multifactor productivity = (400 units)(Tk.10/unit) Tk.4000 = = 2.35 Tk.400 + Tk.1000 + Tk.300 Tk.1700 Productivity Growth Productivity Growth = Current Period Productivity – Previous Period Productivity Previous Period Productivity Productivity Growth Rate Example: – Last week a company produced 150 units using 200 hours of labor – This week, the same company produced 180 units using 250 hours of labor 150 units P1 0.75 units / hour 200 hours 180 units P2 0.72 units / hour 250 hours P2 P1 0.72 0.75 Growth Rate 0.04 P1 0.75 or a negative 4% growth rate
