Evolution vs. Transition vs. Conversion

What word best describes our utility industries' bumpy rides from monopoly markets to competitive markets?  "Evolution" implies natural, gradual change, stimulated by random events.  "Transition" is almost content-free, omitting any sense of who is doing what.   "Conversion" implies active decisions, decisions necessary to overcome resistance and inertia, decisions by government to change legal rights and obligations; by utilities to change asset ownership, pricing options and product mix; by non-utilities to change competitive strategies; and by customers to change shopping practices.   "Conversion," by implying actors and actions, injects accountability by causing one to ask:  Who is acting, what actions are they taking, and are the actions working?
