If you want to be a good reliability engineer ... be helpful. If you are helpful, then people will come back to you. It doesn't matter if you work as a consultant or in a cell in an organization. Too many reliability engineers are more focused on 'doing things right' ... which is another way of saying that we often want people to do things the 'perfect' way as we see it. But being helpful is more important than this. And if you are not helpful, you are not helping.
