Hi, Hollis - excellent post and a most interesting model:)

I think you have captured the essential elements of lasting and true change in your four phasess.  Certainly agrees with my own perceptions and experiences both personally and in working with others.

I do use one of your terms a bit differently.  When I talk about adaptive change, I am referring to the type of change exemplified by your example of the two laid-off real estate agents.  One just shifts to another specific setting while attempting to rebuild what he already knows, while the other one dares to move far beyond and far away.

I take my usage from the literature around adaptive and technical change (which would be the term for the reactive change you describe).

All in all, I thoroughly enjoyed this post:)

John
