"Level ONE change maintains the initial view of the world and the systems to be changed: abandoned, phased out, fixed, replaced, tuned-up, expanded, or downsized. We remain "in the box", with changes that only "tweak" at the edges of the box. Level TWO changes moves us to consider going "out of the box". Systems are created, constructed, reformed; they develop, evolve, and emerge. Construction and reform could be included also as type ONE change. There are varying degrees of level TWO changes, from those that will appear to some to still be "in the box" to radical and awesome shifts that are terrifying to those locked "in their boxes".
