When we take on massive change and we seek to overhaul huge swaths of any organization, system, process and/or culture, we, in essence, create a man-made storm. If we try to predict everything that will happen, we are, just like the so-called "layman experts" described above, deceiving ourselves. Never have I guessed perfectly what would happen, never was I fully prepared, often I have been underwhelmed, but too frequently I have been surprised or overwhelmed.
