To see your process as a whole, you need to really understand your materials. I’ve known companies that teach us a thing or two about materials, but I’ve also worked with engineers who never test the materials they use outside of the normal process. It is obvious when issues arise, that engineers who do material classification ahead of time can react quickly to process changes. They know what they can rule out, how the process can change, and what to do to get a process back into control. Like a puzzle, the big picture is clear when you realize how all of your materials fit together.
