Transformation is an overused word these days. It is a term often attached to any and all kinds of cyclical and structural changes.
True transformational change is far more fundamental to an organization than a new IT system or a shift in structure. Transformational change requires extraordinary leadership at all levels to achieve success.

I came across a good article outlining what leaders must do to ensure transformational change is successful. The authors are 3 McKinsey consultants with extensive experience helping transforming organizations. Their article is Transformation with a Capital T.
