Facilities layout - the grouping and organization of
equipment and employees
Product layout - where each function is performed in a
fixed sequence
Process layout - where each work station is relatively self-
contained
Fixed position layout - where remote work stations
assemble components, and they are then brought to a final
assembly area

The end result of the operations process is the
product – a good or a service. Operations
management includes customer fulfillment process.
Order review / release (ORR) activity: used to
evaluate and track the order through the process:
Creating order documentation
Material checking
Capacity evaluation
Load leveling
The order must be checked to verify it is complete.

Managing Quality
Top management must make improvement in
productivity a strategic objective of the firm.
Top management must also be sure that managers
from different areas of the firm work together to
increase efficiency.
A more efficient production process lowers
production costs, increases profitability, may lead
to lower prices, and attract new customers.
W. Edwards Deming is considered the father of
quality management.

Total Quality Management (TQM)
Continuous improvement of the production
sequence should be one of the main objectives of
operations management.
Total Quality Management (TQM) – based on the
belief that all of an organization’s activities need to be
focused on improving its product.
Four interrelated steps to quality:
Plan
Do
Check
Act
McGraw-Hill © 2004 The McGraw-Hill Companies, Inc. All rights reserved.
Total Quality Management (TQM)
(continued)
Management and TQM
Correct variances in operations management by using TQM
principles to find and correct their source.
Employees and TQM
Operations managers must be sure their employees
understand what TQM means and that each worker is
responsible for improving quality.
Managers must also be willing to act on any suggestions or
problems that employees identify.

Total Quality Management (TQM)
(continued)
Customers and TQM
Operations management can focus on improving the quality
gap – the difference between what customers want and what
they actually get from the company.
Suppliers and TQM
Suppliers are seen as partners with the firm.
TQM and the Production Process
Operations management uses TQM techniques to focus on, and
improve the production process.

Kaizen (Continuous Improvement)
and Efficiency
The Japanese process of continuous improvement
in the organization’s production system from
numerous small, incremental improvements in
production processes.
One of the main principles of kaizen is reducing
waste in materials, inventory, production steps, and
activities that do not add value.

Kaizen
Innovation
McGraw-Hill
Just-in-Time (JIT) Systems
Just-in-time (JIT) – the concept behind creating the
firm’s product in the least amount of time.
Close coordination between manufacturers,
suppliers, and customers.
The firm’s inventory of inputs are kept at the
lowest level possible.
Inputs arrive at the organization when, not before,
they are needed.
McGraw-Hill © 2004 The McGraw-Hill Companies, Inc. All rights reserved.
Kanban
A form of JIT system originated in Japan
Uses cards to generate inventory
From the Japanese word for ―card‖ or ―sign‖
small batches of components to assembly line as
needed

Process Reengineering
Method of changing the entire production process
rather than making incremental changes.
The firm (including its operations management) is
viewed as a complete process.
Involves fundamentally rethinking and radically
redesigning the entire process including:
Cutting out steps that are not needed.
Reducing paperwork.

Quality-centered management of operations is the
key to remaining competitive and can lead to the
survival of the organization.
Effective managers understand and utilize the
concepts and techniques of operations
management.
McGraw-Hill © 2004 The McGraw-Hill Companies, Inc. All rights reserved.
Applications: Management is Everyone’s
Business—For Managing Teams
Team members need the technical skills involved in
measurement and evaluation.
Team members also need interpersonal skills so
that the team structure facilitates rather than gets
in the way of improving production processes.

Applications: Management is Everyone’s
Business—For Individuals
Workers must understand the objectives of the
organization and how they are adding value to the
process.
Individuals make the difference in performance.
Errors, waste, and poor productivity are simply not
acceptable in today’s competitive market.

Decision making (chapter 6)
Human resource management (chapter 10)
Communication (chapter 15)
Control (chapter 16)
Operations management (chapter 17)

Data and Information
Data—raw facts, such as the number of items sold
or the number of hours worked in a department.
Information—data that have been gathered and
converted into a meaningful context.
Useful information is:
High quality
Timely
Relevant
Comprehensive
McGraw-Hill © 2004 The McGraw-Hill Companies, Inc. All rights reserved.
Data and Information (continued)
Databases—computer programs that assign
multiple characteristics to data and allow users to
sort the data by characteristic.
Data warehouses—massive databases that contain
almost all of the information about a firm’s
operations.
Data mining—the process of determining the
relevant factors in the accumulated data to extract
the data that are important to the user.
McGraw-Hill © 2004 The McGraw-Hill Companies, Inc. All rights reserved.
Information Technology
Technology is the means of transforming inputs
into products.
Technology has improved operations management,
including productivity, efficiency, and customer
responsiveness.
A firm’s information technology may incorporate
its operations technology.
Six Functions of Information Technology:
Captures data, Transmits data, Stores information, Retrieves
information, Manipulates information, Displays information
McGraw-Hill © 2004 The McGraw-Hill Companies, Inc. All rights reserved.
Equipment
Local area networks (LAN) link computers in a
firm so users can share information
Servers store information for users linked to them
Wireless equipment—computers no longer require
a physical connection, instead satellites or central
locations create links
McGraw-Hill © 2004 The McGraw-Hill Companies, Inc. All rights reserved.
Computer Networks
LAN
The Internet is a network of networks. It provides:
E-mail
Telnet connections with computers
File transfer protocols (FTP) to move files
World Wide Web provides access to protocols for text, documents,
and images
Extranets (wide area networks) link a company's employees,
suppliers, customers, and other key business partners
Intranets are internal networks that are private or
semiprivate, access is limited to a firm's employees or
certain employees
McGraw-Hill © 2004 The McGraw-Hill Companies, Inc. All rights reserved.
Types of Software
Operating system software tells the computer
hardware how to run
Applications software is developed for a specific
task
Artificial intelligence performs tasks as such as
searching through data and e-mail
Speech recognition software allows customers to
speak numbers when placing orders over the phone
McGraw-Hill © 2004 The McGraw-Hill Companies, Inc. All rights reserved.
Enterprise Resource
Planning (ERP) Software
Combines all of a firm’s computerized
functions into a single, integrated software
program that runs off a single database.
This allows various departments to easily
share information and communicate with
each other.
McGraw-Hill © 2004 The McGraw-Hill Companies, Inc. All rights reserved.
ERP Implementation Reasons
To integrate financial data by providing one set
of numbers for the company’s finance
department, sales department, and individual
business units
To standardize manufacturing processes, so that
a firm with multiple business units can save time,
increase productivity, and reduce staff
To standardize human resources information
about employees and communicating
information about benefits and services

Computer Systems and
Management Issues
Computer Ethics—The analysis of the nature and
social impact of computer technology and the
development of policies for its appropriate use.
Security—Controlling access to and transmission of
data and information contained in the firm’s
network.
McGraw-Hill © 2004 The McGraw-Hill Companies, Inc. All rights reserved.
Reasons for
Computer Ethics
Computer-generated errors are unlike human error.
Computers are able to communicated over the great
distances at low cost.
Computers can store, copy, erase, retrieve, transmit,
and manipulate huge amounts of information quickly
and cheaply.
Computers can depersonalize originators, users, and
subjects of programs and data.
Computers can use data created for one purpose for
another purpose for long periods of time.
