Many people want to know how to analyze problems they meet. 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 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.
After studying the problem, the person should have
A. Six Stages for Repairing Sam’s Bicycle.
