This document outlines the six thinking hats method presented by a group of students. The six hats are blue (managing thinking), white (objective facts), red (intuition and feelings), black (caution and problems), yellow (benefits and feasibility), and green (alternatives and creativity). Each hat represents a different perspective or thinking style. The method can be used by individuals or groups to analyze issues, generate ideas, and make decisions in a structured way by focusing on one hat at a time. Examples are provided of hat sequences like evaluation and design thinking. Benefits of the approach include providing structure, incorporating diverse views, and reducing confrontation.

2. Agenda
 Define parallel thinking
 Identify each of the six hats
 Apply six hats method to problem solving

3. Parallel Thinking
 At any moment everyone is looking in the same
direction.
 Each thinker puts forward his or her thoughts in
parallel with the thoughts of others
 Guides thought processes in one direction at a time so
we can effectively analyze issues, generate new ideas,
and make better decisions.
 Constructive alternative to arguments

4. So the six hats are…?

5. Using the hats
• Use any hat, as often as needed
• Sequence can be preset or evolving
• Not necessary to use every hat
• Time under each hat: generally, short
• Requires discipline from each person – While
using it, stay in the idiom
• Can be used by individuals and groups

6. Blue Hat
Managing the Thinking Process
• Control of thinking & the process
• Instructions for thinking
• The organization of thinking
• Control of the other hats
• Begin & end session with blue hat
• Discipline and focus
• Facilitator, session leader’s role

8. Open with the blue hat….
 Why we are here
 what we are thinking about
 definition of the situation or problem
 what we want to achieve
 where we want to end up
 the background to the thinking
 a plan for the sequence of hats

9. White Hat
Information Available & Needed
 Neutral, objective information
 Facts & figures
 Questions: what do we know, what don’t we
know,
 what do we need to know
 Excludes opinions, hunches, judgements
 Removes feelings & impressions

11. Red Hat
Intuition and Feelings
 Emotions & feelings
 Hunches, intuitions, impressions
 Doesn’t have to be logical or consistent
 No justifications, reasons or basis
 All decisions are emotional in the end

13. Black Hat
Caution, Difficulties, and Problems
 Cautious and careful
 Logical negative – why it won’t work
 Critical judgment, pessimistic view
 Separates logical negative from emotional
 Focus on errors, evidence, conclusions
 Logical & truthful, but not necessarily fair

15. Yellow Hat
Benefits and Feasibility
 Positive & speculative
 Positive thinking, optimism, opportunity
 Benefits
 Best-case scenarios
 Exploration

17. Green Hat
Alternatives and Creative Ideas
 New ideas, concepts, perceptions
 Deliberate creation of new ideas
 Alternatives and more alternatives
 New approaches to problems
 Creative & lateral thinking

19. …and close with the blue hat
 What we have achieved
 Outcome
 Conclusion
 Design
 Solution
 Next steps

20. Hats Activities

21. Single Hat and Sequence Use
 The hats can be used singly at any point in thinking. In
general, this is the major use. The hats are used as a
convenience for directing thinking and for switching
thinking.
 Simple sequences of two or three hats may be used
together for a particular purpose. For example, the
yellow hat followed by the black hat may be used to
assess an idea. The black hat followed by the green
hat may be used to improve a design.

22. Evaluation Sequence
To discover the positive aspects and negative
aspects of an idea. You use the yellow hat
before the black hat. You could follow up with
the green hat (new ideas) and red hat
(feelings) thinking. Examples: Consider positive
and negative
 Not doing homework one night.
 Swapping toys with friends.

23. Caution Sequence
Looking critically at situations. You are first
considering facts with the white hat. Then use
the black hat to discover difficulties. This can
be followed up with some blue hat or red hat
thinking.
Examples: consider the consequences
 Throwing most of your lunch in the bin
everyday.
 Not letting someone know where you are going.

24. Design Sequence
Encourage students to create new ideas,
products or improvements to existing designs.
Use the blue, green and red hats.
Example: use design sequence to create
 A better toothbrush
 Alternatives to homework.

25. Other Sequences
Red + White
 Comparing fact and opinion
Black + Yellow + Green
 Comparing and synthesizing (coming up
with new ideas from the known)
White + Blue
 What do we know (facts) and where are we going
(planning)

26. Benefits of Six Thinking Hats
 Provides a common language
 Experience & intelligence of each person (Diversity of
thought)
 Helps people work against type, preference
 Removal of ego (reduce confrontation)
 Focus (one thing at a time)
 Create, evaluate & implement action plans
