When we challenge the status quo, we test our skills and we challenge ourselves and others towards improvement. I have worked in office where I have asked "Why is it done like that?" and too frequently the answer has been in the region of "That´s just the way we work", or even worse... "That's the way it's always been done".
These are the answers of people who do not understand the reason why. If you cannot articulate the understanding, then you don not know it well enough.
