Question?
Wal-Mart
In the late 1970s, Wal-Mart was a niche marketer, with about 200 stores, mostly in the South. At the time, Sears, JC Penney, and Kmart dominated the retail market. Over the years, Wal-Mart gained market share at the expense of the previous market leaders, and it has now become the largest and most profitable retailer in the world!
Boeing
In the 1990s, the Boeing Company ran into trouble when it could not meet production deadlines. As a result, Boeing lost some orders, which had a negative impact on earnings and its stock price.
Why do some companies thrive while others struggle or fail?
There are a variety of reasons, to be sure. However, an important key in a company’s success or failure is how well it manages its operations.

What is OM(运作管理)
Operations Management (OM): the set of activities(活动) that creates value(价值) in
the form of goods(商品) and services(服务) by transforming inputs into outputs
What activities (어떤 活动이있는가)?
How to evaluate (어떻게 评价핛것인가)?We need evaluation measures – Productivity!!(生产率)What are the better activities?(어떤활동을 어떻게 하면 생산성이 좋을까?)
Production(生产): Creating goods and services

READING!! (Text book)
Why manufacturing matters
The challenges of managing service
U.S. manufacturing versus service employment, 1940-2005
Why?
Productivity and Outsourcing
Decline in Manufacturing Jobs
Productivity
Increasing productivity allows companies to maintain or increase their output using fewer workers
Outsourcing
Some manufacturing work has been outsourced to more productive companies
9
Why Manufacturing Matters
Over 18 million workers in manufacturing jobs
Accounts for over 70% of value of U.S. exports
Average full-time compensation about 20% higher than average of all workers
Manufacturing workers more likely to have benefits
Productivity growth in manufacturing in the last 5 years is more than double U.S. economy
Why Manufacturing Matters
More than half of the total R&D performed is in the manufacturing industries
Manufacturing workers in California earn an average of about $25,000 more a year than service workers
When a California manufacturing job is lost, an average of 2.5 service jobs are lost
10
Challenges of Managing Services
Service jobs are often less structured than manufacturing jobs
Customer contact is higher
Worker skill levels are lower
Services hire many low-skill, entry-level workers
Employee turnover is higher
Input variability is higher
Service performance can be affected by worker’s
personal factors

Why Should Study OM?
4 Reasons OM is one of three major functions of any organization,
and it is integrally related to all the other business functions
We want to know how goods(商品) and services(服务)are produced
We study OM to understand what operations(运作)managers do. By understanding, we can develop the skills necessary to become such a OM Expert
OM is such a costly part of an organization
About 40% of all jobs are in OM

Summary Operations management is responsible for producing goods and providing
services. As such, it is the core function of every business organization. Operations management plans and coordinates the use of the organization’s resources to convert inputs into outputs.
Operations decisions involve design decisions and operating decisions. Design decisions are strategic; they relate to capacity planning, product design, process design, layout of facilities, and selecting locations for facilities. Operating decisions relate to quality assurance, scheduling, inventory management, and project management.
In for-profit organizations, effective operations management can lead to higher productivity, lower costs, higher quality, and other competitive advantages, and increased shareholder wealth. In not-for-profit organizations, effective operations management can lead to lower costs, higher levels of customer service, and more efficient use of resources.
The chapter also presents a brief overview of the historical evolution of operations management and it ends with a list of strategic issues that are currently high priority for business organizations. At the top of that list are the Internet and e-business, outsourcing, supply chain management, management of technology, and agility.
Key Terms Agility(敏捷): The ability of an organization to respond quickly to
demands or opportunities. Craft production(工艺生产): System in which highly skilled
workers use simple, flexible tools to produce small quantities of customized goods.
Division of labor(劳动力分工): The breaking up of a production process into small tasks, so that each worker performs a small portion of the overall job.
E-business(电子商务): Use of the Internet to transact business. E-commerce: Consumer-to-business transactions. Interchangeable parts(通用件): Parts of a product made to such
precision that they do not have to be custom fitted. Lead time(周期): The time between ordering a good or service
and receiving it. Lean production(精益生产): System that uses minimal amounts
of resources to produce a high volume of high-quality goods with some variety
22
Key Terms Mass production(大量生产): System in which low-skilled workers use
specialized machinery to produce high volumes of standardized goods. Model(模型): An abstraction of reality; a simplified representation of
something. Operations management: The management of systems or processes that create
goods and/or provide services. Outsourcing: Obtaining a product or service from outside the organization. Pareto phenomenon( 柏拉图 现象): A few factors account for a high
percentage of the occurrence of some event(s). Six sigma: A process for reducing costs, improving quality, and increasing
customer satisfaction. Supply chain: A sequence of activities and organizations involved in producing
and delivering a good or service. System: A set of interrelated parts that must work together. Technology: The application of scientific discoveries to the development and
improvement of goods and services. Value-added(增值): The difference between the cost of inputs and the value
or price of output

Evaluating Operational Decision Making Performance Measurement
Efficiency(效率) vs. Effectiveness(效力)
Efficiency: Doing something at the lowest possible cost
Effectiveness: Doing the right things to create the most value for the company
Productivity (生产率)
A measurement of how well resources are used
Example: if units produced = 1000 units and labor-hours used is 250, then 1000/250 = 4 units per labor hour
The key factor in Operational Decisions is
to improve productivity!!!

Quiz:
ABS Co. has 10 staffs, each working 8 hrs/day (Payroll cost: $100) and overhead cost $50 per day. This company makes 10 audio sets each day. This company trying to buy new machine that allow the processing of 15 audio sets per day. For using this machine, all things are same except for overhead expenses ($ 100/day)
Analyze the ABS co. in terms of productivity!

61
Quiz: Calculate Productivity
# of staffs 10, each working 8hrs (for a payroll cost of $100/day) and overhead expenses of $50 per day. Output 10 units per day
New system: 15 units per day Overhead cost ->$100 per day
Analysis in terms of Productivity: Labor productivity w/ old system = 10 units per day/80 labor-hour per
day = 0.125 units per labor-hour Labor productivity w/ new system = 15/80 = 0.1875 units per labor-
hour Multifactor productivity w/ old system = 10 units per day/($100+50) =
0.067 units per dollar Multifactor productivity w/ new system = 15/($100 + 100) = 0.075
units per dollar Improvement: (0.1875-0.125)/0.125 = 0.5=> 50 % increased in
labor-productivity 0.075/0.0667 = 1.119=> 11.9% increased in multifactor productivity
Caution: unit

Summary Competition is the driving force in many organizations. It may involve price, quality,
special features or services, time, or other factors. To develop effective strategies for business, it is essential for organizations to determine what combinations of factors are important to customers, which factors are order qualifiers, and which are order winners.
It is essential that goals and strategies be aligned with the organization’s mission. Strategies are plans for achieving organizational goals. They provide focus for decision making. Strategies must take into account present and future customer wants, as well as the organization’s strengths and weaknesses, threats and opportunities. These can run the gamut from what competitors are doing, or are likely to do, to technology, supply chain management, and e-business. Organizations generally have overall strategies that pertain to the entire organization and strategies that pertain to each of the functional areas. Functional strategies are narrower in scope and should be linked to overall strategies. Time-based strategies and quality-based strategies are among the most widely used strategies business organizations employ to serve their customers and to become more productive.
Productivity is a measure of the use of resources. There is considerable interest in productivity both from an organizational standpoint and from a national standpoint. Business organizations want higher productivity because it yields lower costs and helps them to become more competitive. Nations want higher productivity because it makes their goods and services more attractive, offsets inflationary pressures associated with higher wages, and results in a higher standard of living for their people.
