ISAT 430
2. Spring 2001 ISAT 430 Dr. Ken Lewis 2 Process-Property-Product-Performance Continuum Understand how
Product performance
Composition and structure
Synthesis and processing
Assumed behavior
interact
3. Spring 2001 ISAT 430 Dr. Ken Lewis 3 Manufacturing Processes Know what the processes are doing
Changing the state, geometry, physical properties, appearance,…. Changing the value of the material
Know that (in principle) manufacturing adds value to the material.

One of a kind
Labor intensive
A person was a jack of all trades
