I am a Test Engineer. I have the unfortunate responsibility to task aviation parts to break in my bench vs. in the airframe. While I make many engineers unhappy I can see a pattern that the ones following our engineering procedures to the letter rarely make a mistake (which is 99% of our engineers). Redesign is a very low percent and it occurs prior to product release. Also another pattern I see is in the cost reduction budget. While many might think that cost reduction might produce unreliable product I disagree with that mentality. I see that the larger cost reduction budget generally introduces better practices and also fixes previous problems that might not have been spotted. It directly relates to more reliable products as well as better engineering practices. It forces you to revisit old designs and improve them as well as produce them at a lower cost. It's a win-win.
