Ned Herrmann wrote several books on whole brain and creative
             thinking, especially as they relate to the corporation. Initially,
             Herrmann worked for General Electric in management training, but as he
             continued to study and develop his theories on creativity and using the
             whole brain in thinking, he formed his own training group in 1980, the Ned
             Herrmann Group. Herrmann died in 1999, but his work continues being taught
             throughout the world, and the Herrmann Group carries on his work and
             One of the techniques he developed, the Herrmann Brain Dominance
             Instrument (HBDI), is an assessment used to show an individual's "strength
             of preference" in each brain quadrant (Scott). Herrmann broke down the
             brain into four quadrants, A, B, C, and D, and he believed each quadrant
             was used for a specific type of thinking. Quadrant A is the Analyzer, and
             utilizes the areas of logical thinking, analyzing facts, and processing
             numbers. Quadrant B is the Organizer, and utilizes the areas of planning,
             organizing facts, and reviewing details. Quadrant C is the Personalizer,
             and utilizes the areas of interacting, sensing relationships, and
             expressing feelings, and Quadrant D is the Visualizer, and utilizes the
             imagination, thinking about the big picture, and conceptualizing ideas and
             solutions (Scott and Atkin). Herrmann's theories take the "left
             brain/right brain" theories two steps further, and create more depth in the
             areas of the brain, and how they think and react. In fact, Herrmann used
             "the research of Paul McLean (the Triune Brain) and Roger Sperry (Left
             Brain/Right Brain function)," (Atkin) to help develop his own theories and
             methods. Herrmann believed we all have the ability to use each quadrant of
             the brain, but we use some of them more often and more effectively than
             others, and his HBDI helps measure which parts we use the most, and helps
             us use them to our best ability. On...
