Different Ways to Change Management -- "Systems Thinking"

I have been observing the way Organizational change management through leadership has been taking shape for the past two decades. I have seen an explosion in the number of very useful tools to help change agents to effectively explore, understand and communicate about organizations, as well as to guide successful change in those organizations. Systems thinking is a major breakthrough, even if the change agent is not an expert about systems thinking, even a basic understanding can cultivate an entire new way of working.
