I devote a lot of my time helping people and companies get from their present reality to some new reality.  It is rarely easy and - although almost always considered a success - the success is not quite as complete as it could be.  This is the norm; the expectation.  And this is not because of a lack of skill on the part of the consultant (me) or the will of the client.  Rather, it is because the forces that are resisting change are often more powerful than the change agents.

All change involves a conflict between the introduction of new paradigms intended to supplant the old (sometimes, the new paradigm is a reinstatement of an older paradigm) with the intensity of the conflict increasing with the magnitude of the change being of being introduced.
