2. AFTER STUDYING THIS CHAPTER, YOU SHOULD BE ABLE TO:
Differentiate impact on firm when producibility and disposability are internal or external;
Produce with "green engineering" in mind
Design for Producibility and Disposability through life-cycle costing
Create meaningful quantitative measures
Anticipate benefits through integration of life cycle.

7. Manufacturability Quick lead time Inexpensive
Market measures – packaging, handling, storage, and transportation
Forming
Deforming
Removing processes
Joining processes
Material properties modification processes
Use fewer parts, gravity, design for ease of fabrication, reduce nonstandard parts, add more functionality
Automate assembly (inserters, pre-oriented, stable directions, accessibility, handling, avoid flexible components
