When we look at change, we can easily distinguish between planned and unplanned change. In simple terms, planned change is change that we seek. Conversely, unplanned change is the type of change we are forced to accept and integrate. This latter type of change may have been planned by others and we are just the unsuspecting recipients of it; or the unplanned change may be totally unexpected by everyone as in the visit of a tornado and its resulting devastation.
