Eli Whitney Introduced interchangeable
parts in large musket contract for U.S. Army
Interchangeable parts the true secret of Ford’s success
Made possible by advances in measurement and tool steel
Beginning of Standards
Before standardized parts, need Screws
1860s Machine Tool industry: Silicon Valley of its day
All screws custom made by tool & die shops according to what they thought best
William Sellers: 1864 “On a Uniform System of Screw Threads”
Sellers vs. Whitworth
Sellers objectively better Easier: simple angle vs. difficult; rounded top vs. straight 3 cutters & 2 lathes vs. 1 cutter & 1 lathe
Not Just What you Know
Machine tool makers didn’t want to be commoditized like gun makers
The standard people expect to win usually does.
Navy Board found it superior, asked Singer Sewing Machine, Baldwin Locomotive which would win (already adopted).
Pennsylvania RR adopted (Sellers on the Board)
British tanks & trucks couldn’t be repaired in WWII because Britain adopted Whitworth
Frederick W. Taylor
Scientific Management Searching for the “One Best Way” to
do a process Find ways to improve work
environment and work processes Quantify, measure & track
everything:

Frank and Lillian Gilbreth Systematically study a work
environment and find the best way to achieve a particular task
With Taylor, pioneered “industrial engineering” -- time and motion studies
