Intro to business chapter 10
CAD/CAM systems
Linked computer systems that combine the advantages of computer-aided design and computer-aided manufacturing. The system helps design the product, control the flow of resources needed to produce the product, and operate the production process.
scheduling
The aspect of production control that involves specifying and controlling the time required for each step in the production process.
production
The creation of products and services by turning inputs, such as natural resources, raw materials, human resources, and capital, into outputs, which are products and services.
make-or-buy decision
The determination by a firm of whether to make its own production materials or to buy them from outside sources.
enterprise resource planning (ERP)
A computerized resource-planning system that incorporates information about the firm's suppliers and customers with its internally generated data.
Malcolm Baldrige National Quality Award
An award given to recognize U.S. companies that offer goods and services of world-class quality; established by Congress in 1987 and named for a former secretary of commerce.

assembly process
A production process in which the basic inputs are either combined to create the output or transformed into the output.
continuous process
A production process that uses long production runs lasting days, weeks, or months without equipment shutdowns; generally used for high-volume, low-variety products with standardized parts.
intermittent process
A production process that uses short production runs to make batches of different products; generally used for low-volume, high-variety products.
Six Sigma
A quality-control process that relies on defining what needs to be done to ensure quality, measuring and analyzing production results statistically, and finding ways to improve and control quality.
ISO 9000
A set of five technical standards of quality management created by the International Organization for Standardization to provide a uniform way of determining whether manufacturing plants and service organizations conform to sound quality procedures.
just-in-time (JIT)
A system in which materials arrive exactly when they are needed for production, rather than being stored on-site.
flexible manufacturing system (FMS)
A system that combines automated workstations with computer- controlled transportation devices—automatic guided vehicles (AGV)—that move materials between workstations and into and out of the system.
business process management (BPM)
A unified system that has the power to integrate and optimize a company's sprawling functions by automating much of what it does.
Gantt charts
Bar graphs plotted on a time line that show the relationship between scheduled and actual production.
What key trends are affecting the way companies manage production and operations?
Data show the U.S. economy steaming steadily ahead, but dramatic advances in technology, predicted worker shortages, and global competition create challenges for the future. How will companies balance their technology and workforce needs? Will the United States maintain its lead in the ongoing war for leadership in innovation? And what should it be doing to convert today's students into tomorrow's innovators and scientists? Surveys indicate that finding qualified workers continues to be a major concern facing U.S. industry today. If the United States is to maintain its competitive edge, more private and federal investment is needed for science and research. And what of the increasingly crucial role of technology? These are some of the trends facing companies today.
critical path
In a critical path method network, the longest path through the linked activities.
Why is production and operations management important in both manufacturing and service firms?
In the 1980s, many U.S. manufacturers lost customers to foreign competitors because their production and operations management systems did not support the high-quality, reasonably priced products consumers demanded. Service organizations also rely on effective operations management in order to satisfy consumers. Operations managers, the personnel charged with managing and supervising the conversion of inputs into outputs, work closely with other functions in organizations to help ensure quality, customer satisfaction, and financial success.
operations management
Management of the production process.
What roles do technology and automation play in manufacturing and service-industry operations management?
Many firms are improving their operational efficiency by using technology to automate parts of production. Computer-aided design and manufacturing systems, for example, help design new products, control the flow of resources needed for production, and even operate much of the production process. By using robotics, human time and effort can be minimized. Factories are being automated by blending computers, robots, and machinery into flexible manufacturing systems that require less labor to operate. Service firms are automating operations too, using technology to cut labor costs and control quality.
Why are resource-planning tasks such as inventory management and supplier relations critical to production?
Production converts input resources, such as raw materials and labor, into outputs, finished products and services. Firms must ensure that the resources needed for production will be available at strategic moments in the production process. If they are not, productivity, customer satisfaction, and quality may suffer. Carefully managing inventory can help cut production costs while maintaining enough supply for production and sales. Through good relationships with suppliers, firms can get better prices, reliable resources, and support services that can improve production efficiency.
How can quality-management and lean-manufacturing techniques help firms improve production and operations management?
Quality and productivity go hand in hand. Defective products waste materials and time, increasing costs. Poor quality also leads to dissatisfied customers. By implementing quality-control methods, firms can reduce these problems and streamline production. Lean manufacturing also helps streamline production by eliminating unnecessary steps in the production process. When activities that don't add value for customers are eliminated, manufacturers can respond to changing market conditions with greater flexibility and ease.
blockchain technology
Refers to a decentralized "public ledger" of all transactions that have ever been executed. It is constantly expanding, as "completed" blocks are added to the ledger with each new transaction.
How do operations managers schedule and control production?
Routing is the first step in scheduling and controlling production. Routing analyzes the steps needed in production and sets out a workflow, the sequence of machines and operations through which a product or service progresses from start to finish. Good routing increases productivity and can eliminate unnecessary cost. Scheduling involves specifying and controlling the time and resources required for each step in the production process. Operations managers use three methods to schedule production: Gantt charts, the critical path method, and PERT.
value-stream mapping
Routing technique that uses simple icons to visually represent the flow of materials and information from suppliers through the factory to customers.
How do organizations decide where to put their production facilities? What choices must be made in designing the facility?
Site selection affects operating costs, the price of the product or service, and the company's ability to compete. In choosing a production site, firms must weigh the availability of resources—raw materials, manpower, and even capital—needed for production, as well as the ability to serve customers and take advantage of marketing opportunities. Other factors include the availability of local incentives and the manufacturing environment. Once a site is selected, the firm must choose an appropriate design for the facility. The three main production facility designs are process, product, and fixed-position layouts. Cellular manufacturing is another type of facility layout.
lean manufacturing
Streamlining production by eliminating steps in the production process that do not add benefits that customers want.
production planning
The aspect of operations management in which the firm considers the competitive environment and its own strategic goals in an effort to find the best production methods.
routing
The aspect of production control that involves setting out the work flow—the sequence of machines and operations through which the product or service progresses from start to finish.
computer-integrated manufacturing (CIM)
The combination of computerized manufacturing processes (such as robots and flexible manufacturing systems) with other computerized systems that control design, inventory, production, and purchasing.

mass customization
A manufacturing process in which goods are mass-produced up to a point and then custom-tailored to the needs or desires of individual customers.
critical path method (CPM)
A scheduling tool that enables a manager to determine the critical path of activities for a project—the activities that will cause the entire project to fall behind schedule if they are not completed on time.
program evaluation and review technique (PERT)
A scheduling tool that is similar to the CPM method but assigns three time estimates for each activity (optimistic, most probable, and pessimistic); allows managers to anticipate delays and potential problems and schedule accordingly.
ISO 14000
A set of technical standards designed by the International Organization for Standardization to promote clean production processes to protect the environment.
quality
Goods and services that meet customer expectations by providing reliable performance.
cellular manufacturing
Production technique that uses small, self-contained production units, each performing all or most of the tasks necessary to complete a manufacturing order.
What types of production processes do manufacturers and service firms use?
Products are made using one of three types of production processes. In mass production, many identical goods are produced at once, keeping production costs low. Mass production, therefore, relies heavily on standardization, mechanization, and specialization. When mass customization is used, goods are produced using mass-production techniques up to a point, after which the product or service is custom-tailored to individual customers by adding special features. When a firm's production process is built around customization, the firm makes many products one at a time according to the very specific needs or wants of individual customers.
