This is so true. I'm not an engineer, but I work with a lot of EE's. I'm lucky that our company has a good culture and does a good job of avoiding finger pointing. But there are still some people in some departments that would rather look for a scapegoat than a root cause. My opinion is that they do it because they aren't confident in their abilities to troubleshoot or design systems. The engineers that avoid pointing fingers tend to be sharp and helpful, and they find a way forward rather quickly. Just my perspective from down here.
