Lateral Thinking Defined
Lateral thinking is concerned with generation of new ideas.
It is also concerned with "breaking out of the concept prisons of old
ideas."1
Lateral Thinking versus
Vertical Thinking
Lateral thinking is not a substitute for vertical thinking.
Both are required - they are complementary: lateral thinking is generative,
vertical thinking is selective. For instance, during
brainstorming meetings, you encourage
lateral thinking during the first session to generate as much creative
solutions as possible, and vertical thinking during the second session to
select the feasible ideas.
In traditional vertical type of thinking (logic or
mathematic), you move forward by sequential steps each of which must be
justified. You select out only what is relevant. You must be right at each
stage in order to achieve a correct solution.
In lateral thinking, you may deliberately seek out irrelevant
information - you use information not for its own sake but for its effect.
You may have to be wrong at some stage in order to achieve an innovative and
correct solution.
Case in Point: Encouragement
of Lateral Thinking at GE Work-Out
At GE Work-Out,
participants are made fell the urgency to change and begin to see the whole
picture of the situation. Then, they are
ready to focus on new ideas.
How can the process be improved? What can be done differently to achieve the
stretch goal?
"Using the process map as a starting point, Work-Out asks
participants to brainstorm ways
of achieving the goal, and then provides a structure for quickly sorting
through the ideas, selecting the best ones, and developing them into
recommendations for change. As with any brainstorming process, Work-Out
encourages people to toss out any idea, no matter how minor, how crazy, how
seemingly impossible. And the process helps people learn how to build on
each other's ideas, combine ideas, and
think "out-of-the-box." In fact,
when the old Aetna Insurance Company implemented its version of Work-Out,
the program's sponsors called it "Out of the Box."3
