Mass Production …a manufacturing process that lowers the cost required to produce a large number of identical or similar products over a long period of time.
Analytical Process …a process in operations management in which raw materials are broken into different component parts.
Synthetic Process …a process in operations management in which raw materials or components are combined to create a finished product.
Today’s Operations Managers Must Be able to motivate/lead Understand technology Appreciate control processes Understand customer
…the ability of a good or service to satisfy a human need. Utility …the ability of a good or service to satisfy a human need.
Types of Utility Form Place Time Possession
Form Utility …created by converting raw materials, people, finances, and information into finished goods or services.
Figure 8.1: The Conversion Process The conversion process enables business firms to convert ideas and resources such as materials, finances, and information into useful goods and services. The ability to produce products, services, and ideas is a crucial step in the economic development of any nation.
Conversion Process Focus ─ resource(s) that make up the major input Magnitude of change ─ degree to which physical resources are physically changed Number of production processes ─ varies by product/industry
Service Economy …an economy in which more effort is devoted to the production of services than to the production of goods.

Production of Services vs. Goods Services consumed immediately; goods can be stored Services provided when/where customer desires Services usually labor-intensive Services intangible
Major Activities in Operations Management New Product Development Planning for Production Operations Control
Research and Development (R&D) …a set of activities intended to identify new ideas that have potential to result in new goods and services.
Types of R&D Activities Basic Research Aimed at uncovering new knowledge Applied Research Geared toward discovering new knowledge with some potential use Development and Implementation Undertaken specifically to put new or existing knowledge to use in producing goods and services
Product Modification Product extension or refinement gives new life to a product whose sales make up for the declining sales of a product…introduced earlier.
Figure 8.3: Planning for Production
Design Planning …the development of a plan for converting a product idea into an actual product or service.
Requires balancing customer preferences and production requirements Product Line …a group of similar products that differ only in relatively minor characteristics. Requires balancing customer preferences and production requirements
Product Design …the process of creating a set of specifications from which a product can be produced.
Capacity …the amount of products or services that an organization can produce in a given time.
Use of Technology Automation Labor-intensive technology Process in which people do most of the work Capital-intensive technology Process in which machines and equipment do most of the work
Produce a New Product in Existing Factory If Existing has enough capacity Cost of refurbishing is less than cost of building new
Production Facility Location Variables Locations of major customers and suppliers Availability and cost of skilled and unskilled labor Quality of life for employees and management Cost of land and construction Local and state taxes, environmental regulations, zoning laws Financial support from local and state governments Special requirements such as great amounts of energy or water
Plant Layout …arrangement of machinery, equipment, personnel within a production facility.
Figure 8.4: Facilities Planning
Operational Planning Step 1: Selecting a Planning Horizon Step 2: Estimating Market Demand Step 3: Comparing Market Demand with Capacity Step 4: Adjusting Products/Services to Meet Demand
When Demand Exceeds Capacity Operate facility overtime Add 2nd, 3rd shift Outsource a portion Expand current facility or build another
When Capacity Exceeds Demand Reduce number of employees Shorten workweek Close part of facility Shift to production of other goods or services Sell unused facilities
Figure 8.5: Four Aspects of Operations
Purchasing …all activities involved in obtaining required materials, supplies, components, and parts from other firms.
Objective of Purchasing Ensure Required materials Available when needed In proper amounts At minimum cost
Factors in Choosing Supplier Price Quality Reliability Credit Terms Shipping Costs
Inventory Types: Raw Materials Work-in-Process Finished Goods Associated Costs: Holding/Storage Stock-Out
Inventory Control …the process of managing inventories in such a way as to minimize inventory costs, including …holding costs and potential stock-out costs.
Materials Requirements Planning (MRP) …a computerized system that integrates production planning and inventory control.
Extensions of MRP Manufacturing Resource Planning Less-sophisticated software; involves just production and inventory personnel Enterprise Resource Planning More-sophisticated software; can monitor not only inventory and production processes but also quality, sales, etc.
Just-in-Time Inventory System (JIT) …a system designed to ensure that materials or supplies arrive at a facility just when they are needed so storage and holding costs are minimized.
Debate: Should JIT Be Used to Reduce Inventory Costs? YES JIT ensures that materials or supplies arrive when they are needed. JIT reduces inventory storage costs because suppliers must deliver goods when they are needed. Former storage space can be diverted to more productive activities like manufacturing. NO Firm can encounter stock-out costs if supplier doesn’t deliver. Supplier storing goods passes on storage cost in the form of higher prices. If suppliers don’t deliver on time, manufacturer may have to shut down assembly line.
Scheduling …the process of ensuring that materials and other resources are at the right place at the right time.
Scheduling Concerns Place/time Routing of materials Timing Follow-up
Quality Control …the process of ensuring that goods and services are produced in accordance with design specifications.
Malcolm Baldrige National Quality Award Given by U.S. President Results in Better employee relations Higher productivity Greater customer satisfaction Increased market share Improved profitability
…the examination of the quality of work in process. Inspection …the examination of the quality of work in process.
Improving Quality Through Employee Participation Total Quality Management (TQM) program Six Sigma: Disciplined approach that relies on statistical data and improved methods to eliminate defects in products and services
Six Sigma Belts White ─ intensive, short-term training for small-scale or localized quality projects Green ─ extensive training for more-complex or department-wide projects Black ─ long-term training plus hands-on experience; for leading projects involving multiple areas
