First, I hate when people say, "it's not my job". It's a failure of the organization to take ownership.
I've gotten to that point because at my former company design engineers doubled as responsible engineers (a new concept for me), and we would get blamed for a lot of problems. I had a boss that once said about the production line that had thrown up a lot of problems that day, "their job is to build things, we can't take the work out of work."
So I've come to the idea that if it is not your job, it must be mine.
That's one of the fun things for me about being at a startup, especially as we work on these one off facility projects instead of the higher volume products, we don't have a clearly defined structure for who will kit the facility assemblies, so it must be me, I mean, I did design it.
