In my experience, sustainable improvement and change is never achieved by addressing one area with one method. A holistic view is needed. A combination of areas frequently must be addressed in coordination, using multiple means, bridging them together to bring about the desired outcome.
I have always been fascinated with bridging disparate capabilities for bringing about a desired result, whether it is about business strategy and technology, Japanese opportunity with American methods, or Japanese capabilities with opportunities overseas. I remove barriers between functions and cultures, to develop remarkable capabilities together to move an organization toward a desired outcome.
