Looking at a Decision from All Points of View
'Six Thinking Hats' is a powerful technique that helps you look at important decisions from a number of different perspectives. It helps you make better decisions by pushing you to move outside your habitual ways of thinking. As such, it helps you understand the full complexity of the decision, and spot issues and opportunities to which you might otherwise be blind.Many successful people think from a very rational, positive viewpoint. This is part of the reason that they are successful. Often, though, they may fail to look at a problem from an emotional, intuitive, creative or negative viewpoint. This can mean that they underestimate resistance to change, fail to make creative leaps, and do not make essential contingency plans.
Similarly, pessimists may be excessively defensive, and people used to a very logical approach to problem solving may fail to engage their creativity or listen to their intuition.If you look at a problem with the 'Six Thinking Hats' technique, then you will solve it using all approaches. Your decisions and plans will mix ambition, skill in execution, sensitivity, creativity and good contingency planning.
This tool was created by Edward de Bono in his book 6 Thinking Hats.
How to Use the Tool:
To use Six Thinking Hats to improve the quality of your decision-making, look at the decision 'wearing' each of the thinking hats in turn.
Each 'Thinking Hat' is a different style of thinking. These are explained below:
White Hat:With this thinking hat, you focus on the data available. Look at the information you have, and see what you can learn from it. Look for gaps in your knowledge, and either try to fill them or take account of them.This is where you analyze past trends, and try to extrapolate from historical data.
Red Hat:'Wearing' the red hat, you look at the decision using intuition, gut reaction, and emotion. Also try to think how other people will react emotionally, and try to understand the intuitive responses of people who do not fully know your reasoning.
Black Hat:When using black hat thinking, look at things pessimistically, cautiously and defensively. Try to see why ideas and approaches might not work. This is important because it highlights the weak points in a plan or course of action. It allows you to eliminate them, alter your approach, or prepare contingency plans to counter problems that arise.
Black Hat thinking helps to make your plans 'tougher' and more resilient. It can also help you to spot fatal flaws and risks before you embark on a course of action. Black Hat thinking is one of the real benefits of this technique, as many successful people get so used to thinking positively that often they cannot see problems in advance, leaving them under-prepared for difficulties.
Yellow Hat:The yellow hat helps you to think positively. It is the optimistic viewpoint that helps you to see all the benefits of the decision and the value in it, and spot the opportunities that arise from it. Yellow Hat thinking helps you to keep going when everything looks gloomy and difficult.
Green Hat:The Green Hat stands for creativity. This is where you can develop creative solutions to a problem. It is a freewheeling way of thinking, in which there is little criticism of ideas. A whole range of creativity tools can help you here.
Blue Hat:The Blue Hat stands for process control. This is the hat worn by people chairing meetings. When running into difficulties because ideas are running dry, they may direct activity into Green Hat thinking. When contingency plans are needed, they will ask for Black Hat thinking, and so on.
You can use Six Thinking Hats in meetings or on your own. In meetings it has the benefit of defusing the disagreements that can happen when people with different thinking styles discuss the same problem.A variant of this technique is to look at problems from the point of view of different professionals (e.g. doctors, architects, sales directors) or different customers.
You may find our Six Thinking Hats Worksheet useful when you're examining a decision using this technique.
Example:
The directors of a property company are looking at whether they should construct a new office building. The economy is doing well, and the amount of vacant office space is reducing sharply. As part of their decision they decide to use the 6 Thinking Hats technique during a planning meeting.
Looking at the problem with the White Hat, they analyze the data they have. They examine the trend in vacant office space, which shows a sharp reduction. They anticipate that by the time the office block would be completed, that there will be a severe shortage of office space. Current government projections show steady economic growth for at least the construction period.
With Red Hat thinking, some of the directors think the proposed building looks quite ugly. While it would be highly cost-effective, they worry that people would not like to work in it.
When they think with the Black Hat, they worry that government projections may be wrong. The economy may be about to enter a 'cyclical downturn', in which case the office building may be empty for a long time.
If the building is not attractive, then companies will choose to work in another better-looking building at the same rent.
With the Yellow Hat, however, if the economy holds up and their projections are correct, the company stands to make a great deal of money.
If they are lucky, maybe they could sell the building before the next downturn, or rent to tenants on long-term leases that will last through any recession.
With Green Hat thinking they consider whether they should change the design to make the building more pleasant. Perhaps they could build prestige offices that people would want to rent in any economic climate. Alternatively, maybe they should invest the money in the short term to buy up property at a low cost when a recession comes.
The Blue Hat has been used by the meeting's Chair to move between the different thinking styles. He or she may have needed to keep other members of the team from switching styles, or from criticizing other peoples' points.
It is well worth reading Edward de Bono's book 6 Thinking Hats for more information on this technique.
Key points:
Six Thinking Hats is a good technique for looking at the effects of a decision from a number of different points of view.
It allows necessary emotion and skepticism to be brought into what would otherwise be purely rational decisions. It opens up the opportunity for creativity within Decision Making. The technique also helps, for example, persistently pessimistic people to be positive and creative.
Plans developed using the '6 Thinking Hats' technique will be sounder and more resilient than would otherwise be the case. It may also help you to avoid public relations mistakes, and spot good reasons not to follow a course of action, before you have committed to it.

EDWARD DE BONO
"On the Internet there is much misleading and erroneous information about 'lateral thinking' and 'parallel thinkingtm'. Some of the sites make false claims about me and my work. Because this is my official website I want to take this opportunity of clarifying matters regarding lateral thinking and parallel thinkingtm*.
LATERAL THINKING
I invented the term 'lateral thinking' in 1967. It was first written up in a book called "The Use of Lateral Thinking" (Jonathan Cape, London) - "New Think" (Basic Books, New York) - the two titles refer to the same book.
For many years now this has been acknowledged in the Oxford English Dictionary which is the final arbiter of the English Language.
There are several ways of defining lateral thinking, ranging from the technical to the illustrative.
1. "You cannot dig a hole in a different place by digging the same hole deeper"
This means that trying harder in the same direction may not be as useful as changing direction. Effort in the same direction (approach) will not necessarily succeed.
2. "Lateral Thinking is for changing concepts and perceptions"
With logic you start out with certain ingredients just as in playing chess you start out with given pieces. But what are those pieces? In most real life situations the pieces are not given, we just assume they are there. We assume certain perceptions, certain concepts and certain boundaries. Lateral thinking is concerned not with playing with the existing pieces but with seeking to change those very pieces. Lateral thinking is concerned with the perception part of thinking. This is where we organise the external world into the pieces we can then 'process'.
3. "The brain as a self-organising information system forms asymmetric patterns. In such systems there is a mathematical need for moving across patterns. The tools and processes of lateral thinking are designed to achieve such 'lateral' movement. The tools are based on an understanding of self-organising information systems."
This is a technical definition which depends on an understanding of self-organising information systems.
4. "In any self-organising system there is a need to escape from a local optimum in order to move towards a more global optimum. The techniques of lateral thinking, such as provocation, are designed to help that change."
This is another technical definition. It is important because it also defines the mathematical need for creativity.
PARALLEL THINKINGTM
I introduced this term in my book 'PARALLEL THINKING' (published by Viking, London and Penguin Books, London).
Parallel thinking is best understood in contrast to traditional argument or adversarial thinking.
With the traditional argument or adversarial thinking each side takes a different position and then seeks to attack the other side. Each side seeks to prove that the other side is wrong. This is the type of thinking established by the Greek Gang of Three (Socrates, Plato and Aristotle) two thousand four hundred years ago.
Adversarial thinking completely lacks a constructive, creative or design element. It was intended only to discover the 'truth' not to build anything.
With 'parallel thinking' both sides (or all parties0 are thinking in parallel in the same direction. There is co-operative and co-ordinated thinking. The direction itself can be changed in order to give a full scan of the situation. But at every moment each thinker is thinking in parallel with all the other thinkers. There does not have to be agreement. Statements or thoughts which are indeed contradictory are not argued out but laid down in parallel.In the final stage the way forward is 'designed' from the parallel thought that have been laid out.
A simple and practical way of carrying out 'parallel thinking' is the Six HatsTM method which is now being used widely around the world both because it speeds up thinking and also because it is so much more constructive then traditional argument thinking.
Information on Lateral Thinking and Six HatsTM methods are available on this website. Particulars of training courses are also given.

Six Value Medals Brochure
A Revolutionary New Framework, Book, and Course for Leaders, Teams and Individuals From Dr. Edward de Bono
The key to making decisions that will deliver maximum value lies in creating a framework that is specific enough to add meaning but is also pliable enough to expand and contract with each unique challenge.
You'll find a framework robust enough to support these efforts in Edward de Bono's new course, Six Value Medals.
The skills taught in Six Value Medals help people quickly but thoroughly scan for values, prioritize which values are the most important to pursue, and then ensure that top values are addressed and maximized every step of the way. It's like putting on a pair of glasses with six lenses, one for each of the six important value categories.
The Six Value Medals
Gold: Gold is a precious metal, and so are people. The gold medal asks what matters to the people? Human values include pride, achievement, a sense of belonging, hope, trust, and growth.
Silver: Silver medal impacts the organization. What matters to the organization? What are our goals as a company and how will a prospective action help us or hinder us in pursuit of these goals?
Steel: Steel must be as strong as possible. The steel medal asks what are the implications for quality? How will the decision at hand impact the quality of what we do?
Glass: Glass can take the shape of many functional, often beautiful and colorful objects. The glass medal covers change, innovation, simplicity and creativity.
Wood: Wood spotlights ecology values in the broadest sense. Is there a positive or negative impact to the environment if we take this road?
Brass: Brass looks like gold but is not. Brass medal values examine appearances and perception. How will this action be interpreted?
"It is not enough to know that values are important. We need better ways of perceiving values, talking about them and assessing them. That is the best basis for action of any sort. The Six Value Medals framework gives you the tools to do this."
- Dr. Edward de Bono
Too often, organizations cannot articulate the basis for their decisions. As a result, they may fail to notice and resolve conflicts in values that have a negative impact on employees, the organization, clients, community relationships, and more.
Until now there has not been a concrete way to assess the impact that a decision may have on our attempts to create and protect value. When employees can scan, identify, and prioritize values, they become vital partners in growing your business.
"It was very satisfying to watch the participants learn about the Six Values and apply them both to their personal lives and our work here at GMAC Insurance. The feedback from the attendees was very positive, and we are planning another class for March."

The Deming prize, established in December 1950 in honor of W. Edwards Deming, was originally designed to reward Japanese companies for major advances in quality improvement. Over the years it has grown, under the guidance of Japanese Union of Scientists and Engineers (JUSE) to where it is now also available to non-Japanese companies, albeit usually operating in Japan, and also to individuals recognized as having made major contributions to the advancement of quality. The awards ceremoney is broadcast every year in Japan on national television.
Two categories of awards are made annually, the Deming Prize for Individuals and the Deming Application Prize.
