Designing products for manufacturability means that you can build them. Designing for yield reduces costs by minimizing the costs of test, repair, and scrap. The two principles often work at cross-purposes. EE Times explores why both are important, and explains the impact of systematic and random product deviations that affect final results. Can you design for Manufacturability and Yield?

I like that article. It's interesting to look into the issues of a different genre of design and manufacturing.

To create a nice lean design and manufacturing process is valuable in some sense. However, rather than improving existing processes, what is a manufacturing engineer for? Without the ongoing challenges to make new products with new processes there would be limited progress in both design and manufacturing.

I have been in many reviews where the first words from manufacturing were "I can't make that." As a designer (mechanical) I have had to wrestle with manufacturing people in meeting after meeting to get them to agree to develop a process. The interesting thing about this is that once on board they tend to jump in and develop many new solutions.

Design for manufacturing has a place. Design for yield has a place. But it does restrain development.

"What is the object of the act?"

No cross purposes if the enterprise stays focused on the object of the act.
