Slide 3

Improving Creativity

• Creative thinking is often characterized as thinking “outside the box”.

• Creativity can be divided into two phases of thinking:– Divergent thinking– Convergent thinking

Slide 7

Reflective Thinking Process

• The reflective thinking process Dewey (1910) emphasizes the left-brain functions.– Define problem.– Analyze causes.– Identify criteria.– Generate solutions.– Choose best solution.– Implement solution.

Slide 8

The Kepner-Tregoe Approach

• The Kepner-Tregoe approach involves identifying wants and musts. – The most important contribution seems to be the

way in which a group works through the criteria phase.

Fishbone Technique

Slide 10

The Fishbone Technique

• The Fishbone Technique is so called because its outline resembles the skeleton of a fish.– It helps to identify graphically the underlying

causes of a problem.

Slide 11

Brainstorming

• Brainstorming is a lateral thinking process.

• Brainstorming encourages open and random thinking and communications

Slide 12

Brainstorming

• Brainstorming emphasizes right-brain activity.– Rules for brainstorming:

• Put judgment and evaluation aside temporarily.

• Turn imagination loose, and start offering the results.

• Think of as many ideas as you can.

• Seek combination and improvement.

• Record all ideas in full view.

• Evaluate at a later session.

Slide 15

Six Thinking Hats

Six thinking hats is an intuitive way to keep your thoughts focused while problem solving.1. White hat—emotionally neutral.2. Red hat—emotions, gut instincts, intuition, and feelings.3. Black hat—represents careful and analytical thinking.4. Yellow hat—represents sunny, optimistic, and positive

thinking.5. Green hat—represents creativity, new ideas, alternatives,

and possibilities.6. Blue hat—represents coordination, control, and the

discipline to know when to use which hat.

Slide 16

Incrementalism

• Braybrooke and Lindblom (1963) argue that many governmental policies are adopted partially as a result of adapting to political pressure rather than as a result of rational analysis.

Slide 17

Incrementalism

• The term incrementalism refers to the process of making decisions that result in change.– Quadrant 1—High understanding/large change– Quadrant 2—High understanding/incremental

change– Quadrant 3—Low understanding/incremental

change– Quadrant 4—Low understanding/large change

Slide 18

Mixed Scanning

• Etzioni (1968) offers a decision-making strategy that is a combination of reflective thinking and incrementalism.– The ability to maintain a balance between

attention to the general and attention to the specific appears to be a major factor in successful problem solving.

Slide 19

Tacit Bargaining

• Murnighan (1992) refer to “tacit bargaining” as “bargaining in which communication is incomplete or impossible”.– People can cooperate fairly successfully in some

problem-solving situations if it is to their advantage to do so.

• Mixed-motive situations—when there is simultaneous pressure to cooperate and to compete– imply communication procedures that are distinctly different from those in other problem-solving situations.

Slide 20

Virtual decision-making

The decision-making process in the virtual process is a thoughtful and time-consuming process.

–Online tools that help groups make decisions are called decision support systems (DSS).

Slide 21

Review of the Systems Approach

• The decision-making process in most groups can be improved.

• The systems principle of equifinality is that several alternative methods may be used to reach the solution to the group’s problem.

• The appropriateness of any method will depend on the demands of the specific situation.

Slide 22

Review of the Systems Approach

• Rational problem-solving methods work well but seem most suited to an autonomous group trying to satisfy its own needs with a democratic leader.

• Tacit bargaining seems to be primarily appropriate in mixed-motive situations.

• The demands of the situation play a great part in suggesting which problem-solving strategy we want to employ.
