A lot of people seems to complain about the wording. I understand the analogy doesn't cover 100% of the issue but unless somebody finds a better one this is the best we have. Good enough so that stakeholders do sometimes allow us to take care of it. Yes probably not all the time, and not enough, that's why we need to get better at communicating about it. In a corporate environment, communications skill are as important as technical skills, and we should seek to improve both.
