     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 ride 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.
