When I ask “why?” I sometimes get a dismissive reaction as if I asked why because I simply do not know or I am ignorant of the process. How do I phrase the “Why?” so that we can get to a root cause analysis?
What can help a great deal is before launching into asking why, saying something to preface your “why” question, can help people respond appropriately. It could be something like, “In the spirit of working through the causal chain can we ask why? Do we know why the process is the way it is?” This can help set the context behind why you are asking why, and it can help a great deal.
