• Textile manufacturing innovations“Flying shuttle” and “Spinning Jenny”
• J. Watt: The steam engine Substituting labor with machines
• A. Smith: Free markets – division of laborFree markets would enhance “quest” for profit Specialization could increase productivity

The American System of ManufacturingThe American System of Manufacturing
• Vertical IntegrationConsolidating different operations under one roof
• Interchangeable partsMass-produce parts to tight tolerance & assemble1801 contract for 10,000 muskets for the government
• Unskilled workers

• 1832: 36 enterprises in 10 states with > 250 workersReliance on water power & local distribution system
• Transportation innovationsRailroads are built in western world
• Communication innovationsThe telegraph is established
• Big retailers come to powerSears & Roebuck’s sales soar to $38M in 10 years
• Mass Production: the first vehicles arrive… Henry Ford starts producing Model T

• Principles of Scientific ManagementBook published in 1911 by Fredrick Taylor
• Time and Motion studiesHow much time do workers need to do a task?
• Incentive systemsWhat is the best payment scheme?
• Study how systems can be efficientDeveloped a set of principles that serve efficiency.Planning versus doing.
1910-1920: The Scientific Method (Taylorism)1910-1920: The Scientific Method (Taylorism)
Efficiency is the key!

• Application of Taylor’s methodsThe DuPont Powder company
• More importance to the human elementStudies at the Western Electric Hawthorne plant to understand ergonomics: the human element in manufacturing
• Investment in management educationBetween 1914 and 1940 B-schools grew a lot

• Operations Research tools are “born”G.B. Dantzig devises simplex algorithm
• Effort to study complex systemsThe importance of teamwork is introduced
• Mathematical analysis becomes the normScientific methods are applied throughout the organization
• Mathematics solidify the scientific methodSimulation based models, computer usage, scheduling

1980’s: The Japanese Challenge1980’s: The Japanese Challenge
American manufacturing led until the late 70’s, but then…
The methods introduced byJapanese manufacturing firms
outperformed the US …
TQC: Total Quality Control
JIT: Just-In-Time
Higher quality
Less cost

1990’s: The U.S. rises to the challenge1990’s: The U.S. rises to the challenge
Entrepreneurship and the ability to change and re-invent themselves allowed American
firms to move into new areas.
• U.S. firms improve productivity and quality.
• U.S. firms focus on emerging technologies, R&D.
• Growth of the service industry.
• Examples in OM….
