Operations Management
 Operations Management is:
The management of systems or processes
that create goods and/or provide services
 Operations Management affects:
 Companies’ ability to compete
 Nation’s ability to compete internationally

Value-Added and Product Packages
 Value-added elements make the difference
between the cost of inputs and the value or
price of outputs.
 Product packages are a combination of
goods and services.
 Product packages can make a company
more competitive.

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
1-21
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

1-25
Models
A model is an abstraction of reality.
– Physical
– Schematic
– Mathematical
What are the pros and cons of models?
Tradeoffs
1-26
Models Are Beneficial
 Easy to use, less expensive
 Require users to organize
 Increase understanding of the problem
 Enable “what if” questions
 Consistent tool for evaluation and
standardized format
 Power of mathematics
1-27
Limitations of Models
 Quantitative information may be emphasized
over qualitative
 Models may be incorrectly applied and
results misinterpreted
 Nonqualified users may not comprehend the
rules on how to use the model
 Use of models does not guarantee good
decisions
1-28
Quantitative Approaches
 Linear programming
 Queuing techniques
 Inventory models
 Project models
 Statistical models
1-29
Performance Metrics
 To control different aspects of operations
 Many: Profits
Costs
Quality
Productivity
Assets
Inventory
Schedules
Forecast accuracy
1-30
Analysis of Trade-Offs
 Decision on the amount of inventory to stock
 Increased cost of holding inventory
vs.
 Level of customer service
1-31
Systems Approach
“The whole is greater than
the sum of the parts.”
Suboptimization
1-32
Establishing Priorities
 Pareto phenomenon
 A few factors account for a high
percentage of the occurrence of some
event(s).
 80–20 Rule: 80% of problems are caused
by 20% of the activities.
How do we identify the vital few?
1-33
Ethical Issues
 Financial statements
 Worker safety
 Product safety
 Quality
 Environment
 Community
 Hiring/firing workers
 Closing facilities
 Worker’s rights
