People do not analyze every problem they
meet. Sometimes they try to remember a solution from the last time they had a
similar problem. They often accept the opinions or ideas of other people. Other
times they begin to act without thinking. They try to find a solution by trial
and error. However, when all these methods fail, the person with a problem has
to start analyzing. There are six stages in analyzing a problem.
First the person must recognize that there
is a problem. For example, Sam’s bicycle is broken, and he cannot read it to
class as he usually does. Sam must see that there is a problem with his
bicycle.
Next the thinker must define the problem. Before
Sam can repair his bicycle, he must find out the reason why it does not work.
For instance, he must determine if the problem is with the gears, the brakes,
or the frame. He must make his problem more specific.
Now the person must look for information
that will make the problem clearer and lead to possible solutions. For
instance, suppose Sam decided that his bike does not work because there is
something wrong with the gear wheels. At this time, he can look in his bicycle
repair book and read about gears. He can talk to his friends at the bike shop.
He can look at his gears carefully.
After studying the problem, the person
should have several suggestions for a possible solution. Take Sam as an
illustration. His suggestions might be: put oil on the gear wheels; buy new
gear wheels and replace the old ones; tighten or loosen the gear wheels.
Eventually one suggestion seems to be the
solution to the problem. Sometimes the final idea comes very suddenly because
the thinker suddenly sees something new or sees something in a new way. Sam,
for example, suddenly sees that there is a piece of chewing gum between the
gear wheels. He immediately realizes the solution to his problem: he must clean
the gear wheels.
Finally the solution is tested. Sam cleans
the gear wheels and finds that afterwards his bicycle works perfectly. In
short , he has solved the problem.
