XUEMEI SU 1 OUTLINE Describe the four types of processes Explain the product-process matrix Explain the service-positioning matrix Describe how to apply process and value stream mapping for process design Explain mistake proofing in process and product design Explain how to improve process design using process and value stream maps. 2 Major Types of Goods and Service Custom or make-to-order • Produced and delivered as one-of-a-kind or in small quantities • Designed to meet specific customers’ specifications Option or assemble-to-order • Configurations of standard parts, subassemblies, or services that can be selected by customers from a limited set Standard or make-to-stock • Made according to a fixed design, and the customer has no options from which to choose 3 Question: Subway’s sandwich process is best described as? a) custom or make-to-order b) option or assemble-to-order c) standard or make-to-stock d) a value (supply) chain Answer: 4 Types of Processes Projects • Large-scale, customized initiatives that consist of smaller tasks and activities that must be coordinated and completed to finish on time and within budget. Job Shop • Organized around particular types of general-purpose equipment that are flexible and capable of customizing work for individual customers. Flow Shop • Organized around a fixed sequence of activities and process steps, such as an assembly line, to produce a limited variety of similar goods or services. Continuous Flow • Creates highly standardized goods or services, around the clock in very high volumes. 5 Characteristics of Different Process Types 6 Question: An accounting firm specializing in standard EZ tax returns filed online with a similar sequence of steps is best described as what type of process? a) Project b) Job shop c) Flow shop d) Continuous flow Answer: 7 Product Life Cycle A characterization of product growth, maturity, and decline over time. Four phases: Introduction Growth Maturity Decline and turnaround A product’s life cycle has important implications in terms of process design and choice. 8 The Product-Process Matrix Alignment of process choice with the characteristics of the manufactured good Appropriate match between type of product and type of process occurs along the diagonal in the product-process matrix. As one moves down the diagonal, the emphasis on both product and process structure shifts from low volume and high flexibility to higher volume and more standardization. If product and process characteristics are not well matched, the firm will be unable to achieve its competitive priorities effectively. 9 The Product-Process Matrix 10 The Service-Positioning Matrix The product-process matrix does not transfer well to service businesses and processes as the relationship between volume and process is not found in many service businesses. Similar to the product-process matrix Nature of the customer’s desired service encounter activity sequence should lead to appropriate service system design and that superior performance results by staying along the diagonal of the matrix 11 The Service-Positioning Matrix Pathway: a unique route through a service system. Customer-routed services: offer customers broad freedom to select the pathways that are best suited for their immediate needs and wants from many possible pathways through the service delivery system. Provider-routed services: constrain customers to follow a very small number of possible and predefined pathways through the service system. 12 The Service-Positioning Matrix 13 Question: Using the service-positioning matrix, a limited number of customer pathways and highly repeatable service encounter activity sequences would best relate to? a) being below the diagonal b) continuous flow processes c) customer-routed services d) provider-routed services Answer: 14 Process Design The goal of process design is to create the right combination of equipment, labor, software, work methods, and environment to produce and deliver goods and services that satisfy both internal and external customer requirements. Process design can have a significant impact on cost (and hence profitability), flexibility (the ability to produce the right types and amount of products as customer demand or preferences change), and the quality of the output. Four levels: Task Activity Process Value Chain 15 Level of Process Design Task • Specific unit of work required to create an output Activity • Group of tasks needed to create and deliver an immediate or final output Process • Group of activities Value chain • Network of processes 16 The Hierarchy of Work and Cascading Flowcharts for Antacid Tablets 17 Activities of Designing a Goods-producing or Service-providing Process Define the purpose and objectives of the process Create a detailed process or value stream map that describes how the process is currently performed Evaluate alternative process designs Identify and define appropriate performance measures for the process Select the appropriate equipment and technology Develop an implementation plan to introduce the new or revised process design 18 Process and Value Stream Mapping A Process Map (flowchart) describes the sequence of all process activities and tasks necessary to create and deliver a desired output or outcome. A Process Boundary is the beginning or end of a process. The Value Stream refers to all value-added activities involved in designing, producing, and delivering goods and services to customers. A Value Stream Map (VSM) shows the process flows in a matter similar to an ordinary process map, but highlights value-added versus non-value-added activities, and include costs associated with work activities for both value- and non-value-added activities. 19 Process Map for a Restaurant 20 Value Stream Map for a Restaurant Chef’s value of time = $30 per hour Oven operating cost = $10 per hour Precooking order waiting = $5 per hour Postcooking order waiting = $60 per hour 21 Mistake-Proofing Processes Poka-yoke (POH-kah YOH-kay) is an approach for mistake-proofing processes using automatic devices or simple methods to avoid human error. Poka-yoke is focused on two aspects: • prediction, or recognizing that a defect is about to occur and providing a warning and • detection, or recognizing that a defect has occurred and stopping the process. 22 Process Analysis and Improvement Process design activities involve redesigning an existing process to improve performance. Strategies to improve process designs usually focus on increasing revenue, agility, and product and/or service quality, and decreasing costs, process flow time, and the carbon footprint. Reengineering is defined as fundamental rethinking and radical redesign of business processes to achieve dramatic improvements in critical, contemporary measures of performance. 23 KEY TERMS Custom or make-to-order, Option or assemble-to-order, Standard or make-to-stock, Projects Job shop processes Flow shop processes Continuous flow processes Product-process matrix Pathway Customer-routed services Provider-routed services Task Activity Process Process map (Flowchart) Process boundary Value stream mapping Reengineering
