This is a great article. I remember reading this a few years ago during my undergrad- my big takeaway from it was that sometimes you will encounter bugs which you can't solve alone. I always assumed any error I came across was my fault, but that's not good (it's also not good to just assume it's someone else's). Fixing problems in an organization is often a team effort that requires good communication and incentive for improvement- not just one genius coder that knows the whole source code.
