"6 THINKING HATS" METHOD- A method in which a group is separated into 6 distinct roles using color coated hats that translate into how the person acts; e.g. red signifies intuition and black, judgement.
Myers-Briggs Type Indicator (MBTI)- A personality test in which people, based on answers they give are separated into a personality type; e.g. INTJ ( Introversion, Intuition, Thinking, and Judgement.) The people who are placed together is based on that type if this method is to be used.
Theoretical Advantages/ Benefits= A) Multiple views to something that provides a clearer understanding of topic. B) A various amount of skills that can contribute to different aspects of assignment.
Theoretical Disadvantages/ Challenges= A) Due to the various personalities, group tends to sub group into "their type" and may want to achieve the common goal in a different way. B) Almost everyone will think they are best fit to be the leader of the group because they have a particular set of skills that others don't.
When would these methods be useful? The "6 Thinking Hats" Method would be useful in groups of 6 or less because there are only 6 hats. The "MBTI" Method will be useful if a homogeneous group based on personality was a requirement.
When would these methods NOT be useful? The "6 Thinking Hats" Method is designed for individuality, so when the group consists of MORE than 6 people, the roles of the person with a hat will have to be shared with another. The "MBTI" method is set so that certain people of the SAME personality type are put together. When that happens, either everyone is in a competition for leadership, OR everyone doesn't want to contribute.
