Current Challenges in Operations Management 2 1 2/5/2020 What Is Operations Management? Operations are the part of a business organization that is responsible for producing goods or services. Operations management (OM) is the design, improvement, and the management of systems or processes that create value by converting inputs, such as raw materials, labor, and/or customers into outputs, such as goods or services. OM is the business function responsible for planning, coordinating, and controlling the resources needed to produce a company’s goods and services. 3 Examples of Operations Back office operation in a bank They are all operations Kitchen unit manufacturing operation Retail operation Take-out / restaurant operation 4 2 2/5/2020 Concept of Operations Management For operations management to be successful, it must add value during the transformation process. The term value added describe the net increase between the final value of a product and the value of all the inputs. The greater the value added, the more productive a business is. An obvious way to add value is to reduce the cost of activities in the transformation process. 5 Operations Management at IKEA Design elegant products which can be flat-packed efficiently Design a store layout which gives smooth and effective flow Site stores of an appropriate size in the most effective locations Maintain cleanliness and safety of storage area Ensure that the jobs of all staff encourage their contribution to business success Continually examine and improve operations practice Monitor and enhance quality of service to customers Arrange for fast replenishment of products 6 3 2/5/2020 Good or Service? Goods are physical items that include raw materials, parts, subassemblies, and final products. Automobile Computer Oven Shampoo Services are activities that provide some combination of time, location, form or psychological value.

Goods Services Surgery, Teaching Songwriting, Software Development Computer Repair, Restaurant Meal Home Remodeling, Retail Sales Automobile Assembly, Steelmaking 17 Characteristics of Goods Tangible product Consistent product definition Production usually separate from consumption Can be inventoried Low customer interaction 18 9 2/5/2020 Characteristics of Service Intangible product Produced and consumed at same time Often unique High customer interaction Inconsistent product definition Often knowledge-based Frequently dispersed 19 Manufacturing vs. Service? Manufacturing and Service Organizations differ chiefly because manufacturing is goods-oriented and service is act-oriented. Goods Tangible Services Act-Oriented 1-20 20 10 2/5/2020 Managing Services is Challenging 1. 2. 3. 4. 5. 6. 7. Jobs in services are often less structured than in manufacturing Customer contact is generally much higher in services compared to manufacturing In many services, worker skill levels are low compared to those of manufacturing employees Services are adding many new workers in low-skill, entry-level positions Employee turnover is high in services, especially in low-skill jobs Input variability tends to be higher in many service environments than in manufacturing Service performance can be adversely affected by many factors outside of the manager’s control (e.g., employee and customer attitudes) 21 Process Management Process - one or more actions that transform inputs into outputs Three Categories of Business Processes: Upper-management processes These govern the operation of the entire organization. Operational processes These are core processes that make up the value stream. Supporting processes These support the core processes. 22 11 2/5/2020 Supply & Demand Operations & Supply Chains Sales & Marketing Supply > Demand Supply < Demand Supply = Demand Wasteful Costly Opportunity Loss Customer Dissatisfaction Ideal 23 Process Variation Four Sources of Variation: Variety of goods or services being offered The greater the variety of goods and services offered, the greater the variation in production or service requirements. Structural variation in demand These are generally predictable. They are important for capacity planning. Random variation Natural variation that is present in all processes. Generally, it cannot be influenced by managers. Assignable variation Variation that has identifiable sources (defective inputs, incorrect work methods, out-of-adjustment equipment). This type of variation can be reduced, or eliminated, by analysis and corrective action. Variations can be disruptive to operations and supply chain processes. They may result in additional costs, delays and shortages, poor quality, and inefficient work systems. 24 12 2/5/2020 Scope of Operations Management The scope of operations management ranges across the organization. The operations function includes many interrelated activities such as: Forecasting (e.g., seat demand for flights and growth in air travel) Capacity planning (e.g., Too few or too many planes, or even the right number of planes but in the wrong places, will hurt profits) Locating facilities (e.g., which cities to provide service for, where to locate maintenance facilities, and where to locate major and minor hubs) Scheduling (e.g., planes for flights and for routine maintenance; and scheduling of ground crews, counter staff, and baggage handlers) Managing inventories (e.g., foods and beverages, first-aid equipment, inflight magazines, pillows and blankets, and life preservers) Assuring quality (e.g., in flying and maintenance operations, where the emphasis is on safety, and in dealing with customers at ticket counters, check-in, where the emphasis is on efficiency and courtesy). Motivating employees And more . . . 25 Role of the Operations Manager The Operations Function consists of all activities directly related to producing goods or providing services. An important role of operations is to analyze all activities, eliminate those that do not add value, and restructure processes and jobs to achieve greater efficiency. A primary function of the operations manager is to guide the system by decision making. System Design Decisions (strategic decisions) System Operation Decisions (tactical and operational decisions) 26 13 2/5/2020 System Design Decisions These are typically strategic decisions that usually require long-term commitment of resources Set the direction for the entire company Decisions about: What to make (product development)? How to make it (process and layout decisions) or should we buy it? Where to make it (site location)? How much capacity is needed (high level capacity decisions)? 27 System Operation Decisions System Operation These are generally tactical and operational decisions Operations managers spend more time on system operation decision than any other decision area They still have a vital stake in system design because system design essentially determines many of the parameters of system operation. For example, costs, space, capacities, and quality are directly affected by design decisions. 28 14 2/5/2020 Tactical Decisions Tactical (Intermediate Term) Level Addresses the material and labor resources within the constraints, for example: How many workers are needed and when (labour planning)? What level of stock is required and when should it be delivered (inventory and replenishment planning)? How many shifts needed for work? Whether overtime or subcontractors are required (detailed capacity planning). 29 Operational Decisions Operational (Short Term (daily/weekly/monthly) Level) Planning, execution and control decisions, such as, for example: What to process and when (scheduling)? What is the order to process requirements (sequencing)? How does the work utilize the resources (loading)? Who does the work (assignments)? 30 15 2/5/2020 Decision Making Most operations decisions involve many alternatives that can have quite different impacts on costs or profits Typical operations decisions include: What: What resources are needed, and in what amounts? When: When will each resource be needed? When should the work be scheduled? When should materials and other supplies be ordered? Where: Where will the work be done? How: How will he product or service be designed? How will the work be done? How will resources be allocated? Who: Who will do the work? 31 Strategic Decisions Product Design: What good or service should we offer and how should we design these products and services? Managing quality: How to define quality and who is responsible for quality? Process and capacity design: What process and what capacity will these products require? What equipment and technology is necessary for these processes? Location strategy: Where should we put the facility? On what criteria should we base the location decision? Layout strategy: How should we arrange the facility? How large must the facility be to meet our plan? Human Resources and job design: How to provide a reasonable work environment? How much can we expect our employees to produce? 32 16 2/5/2020 Strategic Decisions Supply Chain Management: should we make or buy this component? Who are our suppliers and who can integrate into our e-commerce program? Inventory management: How much inventory of each item should we have? When do we re-order? Planning (aggregate and short-term): Are we better off keeping people on the payroll during slowdowns? which job do we perform next? Maintenance: who is responsible for maintenance? When do we do maintenance? 33 Degree of Customization Relative to other standardized products and services customized products: Tend to be more labor intensive Tend to be more time consuming Tend to require more highly-skilled people Tend to require more flexible equipment Have much lower volume of output Have higher price tags Degree of customization has a significant influence on the entire organization Process selection Job design Affects marketing, sales, accounting, finance, and information systems 34 17 2/5/2020 Systems Approach System - a set of interrelated parts that must work together The business organization is a system composed of subsystems marketing subsystem operations subsystem finance subsystem The systems approach Emphasizes interrelationships among subsystems, but Its main theme is that the whole is greater than the sum of its parts The output and objectives of the organization take precedence over those of any one subsystem 35 Systems Approach-Example If the upcoming model of an automobile will add antilock brakes, a designer must take into account how customers will view the change, instructions for using the brakes, chances for misuse, the cost of producing the new brakes, installation procedures, recycling worn-out brakes, and repair procedures. In addition, workers will need training to make and/or assemble the brakes, production scheduling may change, inventory procedures may have to change, quality standards will have to be established, advertising must be informed of the new features, and parts suppliers must be selected. 36 18 2/5/2020 Key Trends and Issues in Business • • • • • • • E-Business & E-Commerce Management of Technology Globalization Management of Supply Chains Outsourcing Sustainability and Green Operations Agility (the ability of an organization to respond quickly to demands or opportunities) • Lean system (system that uses minimal amounts of resources to produce a high volume of high-quality goods with some variety) • Ethical Behavior 37 19
