People do not analyze every problem theymeet. Sometimes they try to remember a solution from the last time they had asimilar problem. They often accept the opinions or ideas of other people. Othertimes they begin to act without thinking; they try to find a solution by trialand error. However, when all these methods fail, the person with a problem hasto start analyzing. There are six stages in analyzing a problem.
First the person must recognize that thereis a problem. For example, Sam′s bicycle is broken, and he cannot ride it toclass as he usually does. Sam must see that there is a problem with hisbicycle.
Next the thinker must define the problem.Before Sam can repair his bicycle, he must find out the reason why it does notwork. For instance, he must determine if the problem is with the gears, thebrakes, or the frame. He must make his problem more specific.
Now the person must look for informationthat will make the problem clearer and lead to possible solutions. Forinstance, suppose Sam decided that his bike does not work because there is somethingwrong with the gear wheels. At this time, he can look in his bicycle repairbook and read about gears. He can talk to his friends at the bike shop. He canlook at his gears carefully.
After studying the problem, the personshould have several suggestions for a possible solution. Take Sam as anillustration. His suggestions might be: put oil on the gear wheels; buy newgear wheels and replace the old ones; tighten or loosen the gear wheels.Eventually one suggestion seems to be the solution to the problem. Sometimesthe final idea comes very suddenly because the thinker suddenly sees somethingnew or sees something in a new way. Sam, for example, suddenly sees that thereis a piece of chewing gum between the gear wheels. He immediately realizes thesolution to his problem: he must clean the gear wheels.
Finally the solution is tested. Sam cleansthe gear wheels and finds that afterwards his bicycle works perfectly. Inshort, he has solved the problem.
