PRODUCTION AND
OPERATIONS
MANAGEMENT
2
OBJECTIVES
Introduction to Production Function and
Operations Management
Mass Production Approach
Toyota Production System (TPS)
Approach
Supply Chain Management
3
PRODUCTION
versus MANUFACTURING
Production is a Broader Term that Spans
both Manufacturing and Services
Functions
Production is the Application of
Resources, People and Machinery,
to Convert Inputs into Finished Goods
and Services
4
MASS PRODUCTION
Mass Production: Makes Outputs available in
Large Quantities at Lower Unit Costs than
Individually- Crafted Items
Characteristics of Mass Production
Labor Specialization
Mechanization
Standardization
5
ASSEMBLY LINES
Assembly Line first Introduced by Eli Whitney
(Cotton Gin Inventor) to build Muskets for the
US Government In 1799
Used Ideas of Specialized Labor and Engineering
Standards (Tolerances) to produce Assemblies
from Parts in Repeatable Manner
6
HENRY FORD
Introduced Moving Assembly Line: Dramatically
Reduced Manufacturing Costs While Delivering
Consistent, Low-Priced Product
Factory based on Chicago Meat Cutting Plants
7
FORD MODEL T
First Produced:
October 1908
By 1927,
15,000,000
Produced
Any Color so long
as its Black
8
ASSEMBLY LINE BENEFITS
 Initially, took 14 hours to Assemble
Model T - Mass Production reduced
Time to 1 Hour and 33 Minutes
 Model Ts Price dropped from $1,000
in 1908 to $360 in 1916
 Result was Ford becoming
Dominant Automobile Manufacturer
and Assembly Line Method as
Dominant Production Approach
9
FORD ASSEMBLY LINES
Assembly Line pulled by Ropes Magneto Assembly
10
MASS PRODUCTION
MODEL T  Machine that Changed the
World
 1914: Ford produced 308,162 cars, more than
all 299 other auto manufacturers combined
 1927: Automobile Produced every 24 seconds
 Higher volumes  Lower cost  Lower Prices
Increased Sales  Higher Volumes
11
MASS PRODUCTION
PUSH Strategy  Driven by Inputs and Objectives
Control of Raw Materials and Labor plus Profit Goals =
Production Rate separate from Customer Demands
and Preferences
Performance measured by Budget Variances and
Quantitative Results (Defects or Unit Costs per Day,
Week or Month), not Quality Standards
12
MASS PRODUCTION
 Low Product Variety; Small Orders Not Feasible
 Specialized Machinery and Centralized Manufacturing
 Economies of Scale  High-Speed Sequential
Production
 Development Costs Spread Over Large Volume:
Low Cost per Unit Produced
 Low-Skill/Low-Wage Work Force
 Large Advertising and Marketing Budgets
13
FORD WORKING CONDITIONS
Monotony of Assembly Line Work: 300% Turnover
 $2 per Day and a 9-Hour Shift
Fords Response to Working Conditions Dilemma
 Increase Pay to $5 per Day and
Reduce Shifts from 9 Hours to 8 Hours
The Chain System you have is a Slave Driver. My God,
Mr. Ford! My Husband has come Home and Thrown
Himself Down and wont Eat his Supper, Hes so
done out. Cant it be Remedied? That $5-a-day is a
Blessing; a Bigger One than you Know. But, Oh,
They Earn It!
- Wife of Ford Assembly Line Worker

MASS PRODUCTION
Flaws of Mass Production Approach
 Production Levels cannot Stop or Slow:
Defects resolved outside Production (Added
Costs of Rework)
 Long Changeover Times limits Product Variety
 Erratic Finished Products Inventory Levels
Incentives and 0% Financing
15
MASS PRODUCTION
Market Orientation Flaw
16
TOYOTAS ORIGINS
1902 Modification: Loom
Stopped Automatically if
Thread Broke or Spool
Empty - Signal for
Attention
Result: No Waste from
Defective Work and
Lower Production Costs
Toyoda Automated Loom Works
17
TOYOTAS ORIGINS
During WWII, Toyoda became Toyota and manufactured
Motorcycles and Delivery Trucks
After WWII, Japanese Industry needed to re-build
18
TOYOTAS ORIGINS
Found Mass Production Principles not Applicable:
 Scale of Japanese Markets
 Desire for Product Variety
 Unable to Afford Resources and Inventories
1956  Taiichi Ohno went to US
to study Fords Manufacturing
Facilities
19
TOYOTAS ORIGINS
Discovered Production and Operation Methods that
 Were Linked to Customer Actions: Inventories
Replenished by Sales (PULL Strategy)
 Delivered Product Variety and Scale
 Minimized Waste
Before returning to
Japan, Ohno went to an
American Grocery Store
20
TOYOTAS ORIGINS
Toyota Exports its
First Car: The
Forgettable
Crown
Under-powered
and Unstable at
Freeway speeds,
Production is
stopped in 1959
21
TOYOTA PRODUCTION
SYSTEM
In 1961, Toyota adopts Systems Perspective
KAIZEN  Continuous Improvement Attitude
that Minimizes Waste and Emphasizes
High Quality
Processes are analyzed to eliminate flaws
rather than fixing defective products
WASTE  Comprehensive View that includes
Time, Resources and Materials
Over-Production
Time Spent Waiting
Unnecessary Movements of Items
22
TOYOTA PRODUCTION
SYSTEM
Waste is anything other than the
minimum amount of equipment,
materials, parts, space, and
workers time which are absolutely
essential to add value to the product.
- Shoichiro Toyoda
President, Toyota Motor
Co.
