Six thinking hats

In human resource management course of MBA, the professor made mention of "six thinking hat" method for using in decision making. I am so interesting for this topic so I searched the relatied info and shown roughly below,

Early in the 1980s Dr. Edward de Bono invented the Six Thinking Hats method. The method is a framework for thinking and can incorporate lateral thinking. Valuable judgmental thinking has its place in the system but is not allowed to dominate as in normal thinking. Dr. de Bono organized a network of authorized trainers to introduce the Six Thinking Hats.

The key point is that a hat is a direction to think rather than a label for thinking. The key theoretical reasons to use the Six Thinking Hats are to:

encourage Parallel Thinking

encourage full-spectrum thinking

separate ego from performance

There are six metaphorical hats and the thinker can put on or take off one of these hats to indicate the type of thinking being used. This putting on and taking off is essential. The hats must never be used to categorize individuals, even though their behavior may seem to invite this. When done in group, everybody wear the same hat at the same time.

White Hat thinking (Objective)
This covers facts, figures, information needs and gaps. "I think we need some white hat thinking at this point..." means Let's drop the arguments and proposals, and look at the data base."

Red Hat thinking (Intuition)
This covers intuition, feelings and emotions. The red hat allows the thinker to put forward an intuition without any need to justify it. "Putting on my red hat, I think this is a terrible proposal." Ususally feelings and intuition can only be introduced into a discussion if they are supported by logic. Usually the feeling is genuine but the logic is spurious.The red hat gives full permission to a thinker to put forward his or her feelings on the subject at the moment.

Black Hat thinking (Negative)
This is the hat of judgment and caution. It is a most valuable hat. It is not in any sense an inferior or negative hat. The prior or negative hat. The black hat is used to point out why a suggestion does not fit the facts, the available experience, the system in use, or the policy that is being followed. The black hat must always be logical.

Yellow Hat thinking (Positive)
This is the logical positive. Why something will work and why it will offer benefits. It can be used in looking forward to the results of some proposed action, but can also be used to find something of value in what has already happened.

Green Hat thinking (Creative)
This is the hat of creativity, alternatives, proposals, what is interesting, provocations and changes.

Blue Hat thinking (Process)
This is the overview or process control hat. It looks not at the subject itself but at the 'thinking' about the subject. "Putting on my blue hat, I feel we should do some more green hat thinking at this point." In technical terms, the blue hat is concerned with meta-cognition.

Personal comment: We are suggested to think in six sides on one matter, it is comprehensive thinking method not only included postive side and negative side. Green hat thinking recommends us to think out of the box. We can get more creative and better ideas based on the original proposal! Blue hat thinking is the evaluation of overall thinking or proposal, it aimed to a process control function. The red hat thinking shown us the side which is not covered by the physical data.

Yes! I got some ideas from the theory right now!
