One of the challenges to such work is quickly assessing the strengths & weaknesses in the engineering personnel & management dynamics. There are times where the politics are more difficult to address than the complex technical failure issue itself. There are ways in dealing with tough situations where firmness is applied, but if there is a solution where you are able to build upon guiding/teaching/helping others, that is a path I always try to take.
