At the core of Ned Herrmann's most recent book lies his belief that the functioning of the human brain is driven by a four-quadrant interconnected set of mental processing modes. These four thinking styles, says Herrmann, originate in the brain's left and right cerebral hemispheres, and in the left and right half limbic systems, each resulting in significantly different and distinct behavioral characteristics in human beings. How this complex brain interaction determines thinking mode dominance and thinking style preferences, and how individuals and organizations can benefit from such understanding, are the main themes of this highly thought provoking and exceptionally relevant management book. Herrmann's work is widely thought of by training and development specialists as superseding earlier "left brain/right brain" thinking models as well as having advanced new concepts of mind research and their applications in business settings. In fact, this is the first book exclusively dedicated to applying whole brain thinking to a wide range of business situations.Thinking dominance by one of the four styles leads to the development of preferences, which in turn establish our interests, foster the development of competencies, and influence our career choices and ultimately the work that we do, contends Herrmann. Knowing whether you, your organization, or a particular job, is predominantly quadrant A, B, C, or D oriented, makes all the difference whether or not relationships have an opportunity to develop and flourish or to remain counter-productive and underutilized. Mismatching people and assignments by not using whole brain thinking processes can be extremely costly, both in terms of individual psychological danage and in terms of negative organizational results, suggests Herrmann.Knowing your thinking preference is a good place to start understanding whole brain technology. You can get an idea of whether you are an Analyser, Organizer, Personalizer, or Visualizer (Quadrants A, B, C, and D, respectively), by completing the Preference Indicator Exercise provided in the book. Better yet, you can complete the HBDI (Herrmann Brain Dominance Instrument) survey, which, when evaluated by trained specialists from the Ned Herrman Group, will result in your own HBDI Personal Profile.
