The document discusses the technique of lateral thinking, which is about changing concepts and perceptions to discover non-obvious ideas. It contrasts lateral thinking with logical thinking, noting that lateral thinking aims to generate many alternatives without judgment, while logical thinking searches for the single best approach. The document then provides examples of lateral thinking exercises, where participants must solve problems by breaking assumptions and thinking differently. It emphasizes that lateral thinking can help develop out-of-the-box ideas by challenging norms and generating new possibilities.

… yes, but how?

3. P. G. Tello
The most difficult to achieve is to…
Challenge Assumptions
Generate new possibilities

4. P. G. Tello
A useful technique
LATERAL THINKING is a method of thinking
concerned with changing concepts and perception.
It is about discovering what is not immediately
obvious, and about ideas that may not be
obtainable by using only traditional step-by-step
logic.
Dr. Edward deBono

5. P. G. Tello
Logical thinking is primarily
concerned with judging the
true value of statements and
seeking errors. It is very
helpful when we implement
solutions.
But there comes a time when
one cannot proceed further
without restructuring the
pattern…
…without breaking up the
old pattern which has been
so useful and arranging the
old information in a new
way.
?

Breaking up the
old pattern and
generating a
new possibility

7. P. G. Tello
Lateral vs Logical thinking…
Logical search Lateral search
One is looking for the BEST
POSSIBLE approach.
One is trying to produce as MANY
ALTERNATIVES as possible.
One stops when one comes to a
promising approach.
One acknowledges the promising
approach and may return to it later
but goes on to generating others.
One considers only reasonable
alternatives.
Alternatives do not have to be
reasonable.
Purpose: search for the best one. Purpose: To loosen up rigid patterns
and provoke new patterns.

Enough theory…
…let’s go for the practice
(each exercise 7 min and 1 to explain solution)
( work in teams and select a presenter)

10. P. G. Tello
Exercise 1
How would you divide a square
into four equal pieces?

11. P. G. Tello
Solution 1
Did you consider any of these?

12. P. G. Tello
Exercise 2
Problem:
A landscape gardener is given instructions to
plant four special trees so that each one is
exactly the same distance from each of the
others.

13. P. G. Tello
Solution 2
One tree is planted on top of a
hill.
(the broken assumption is that
they are all planted on a leveled
piece of ground).

14. P. G. Tello
Exercise 3
IX
Add a single line to turn
this into a six;
generate as many solutions
as you can.

15. P. G. Tello
Solution 3
SIX
IX6
Generated possibilities by broken
assumptions
• 6 can be written in different ways
• Lines are also curve

16. P. G. Tello
Exercise 4
What do you read in the figure
above?

17. P. G. Tello
Solution 4
Flip/Flop
Broken assumption: o can be an i
(figure/background)

18. P. G. Tello
Exercise 5
There are six glasses in a row. The first three are full of water,
and the next three are empty.
By moving only one glass how can you make them alternate
between full and empty?

19. P. G. Tello
Solution 5
Pour the water from the 2nd glass into the 5th glass.

20. P. G. Tello
Exercise 6
We are in the 50’s so no mobiles exist
yet. You are driving down the road in
your car on a wild, stormy night in a
lonely place.
You pass by a bus stop and you see three
people waiting for the bus:
• An old lady who is sick and needs to
be taken to the hospital.
• An old friend who once saved your
life.
• The perfect partner you have been
dreaming about.
Knowing that there can only be one
passenger in your car, whom would you
choose?
Hint:
You can make everyone
happy including yourself

21. P. G. Tello
Solution 6
The old lady of course!
After helping the old lady into the car, you can give
your keys to your friend, and wait with your perfect
partner for the bus.

22. P. G. Tello
Exercise 7
Move the minimum number of sticks to make this
operation right.

23. P. G. Tello
Solution 7
Flip it upside down and you have it moving zero sticks
I + IX = X

Exercise 8
Move just two coins to form two lines,
each containing six coins.

25. P. G. Tello
Solution 8

26. P. G. Tello
Exercise 9
Suppose you want to start restaurant and have difficulties to come up with
ideas. You then decide to list three assumptions and reverse them.
Assumption
•a) Restaurants have menus either written, verbal
or implied.
•b) Restaurants charge money for food.
•c) Restaurants serve food.
Reverse
•a’) Restaurants have no menus of any kind.
•b’) Restaurants give food away for free.
•c’) Restaurants do not serve food of any kind.
Come up with an idea for each one of the reversals

27. P. G. Tello
Solution 9
Reverse
•a’) Restaurants have no menus of any kind.
•b’) Restaurants give food away for free.
•c’) Restaurants do not serve food of any kind.
Idea
•a’) The chief informs the client of what he bough that day.
Asks the customers what ingredients appeal to them and cooks
an exclusive dish. Recipe will be sent to them by email.
•b’) An outdoor café where customers pay for time instead of
food. Use a time stamp to charge by the minute. Selected food
or beverages are sold for free.
•c’) Create a restaurant with a unique décor in an exotic
environment and rent out the location. People bring their own
food and beverages and pay a service charge for the location.

Messages to take home…
Lateral thinking is a useful technique to
actually learn how to think out of the box.
It is complementary to our more familiar
logical and critical thinking mode.
Practise it as much as you can.

29. P. G. Tello
Most important…
Challenge assumptions
and
Generate new different solutions

30. P. G. Tello
