We can see how the product life cycle works by looking at the introduction of instant coffee. When it was introduced, most people did not like it as much as "regular" coffee and it took several years to gain general acceptance (introduction stage). At one point, though, instant coffee grew rapidly in popularity and many brands were introduced (stage of rapid growth). After a while people became attached to one brand and sales leveled off (stage of maturity). Sales went into a slight decline when freeze-dried coffees were introduced (stage of decline).
　　The importance of the product life cycle to marketers is this: different stages in the product life cycle call for different strategies. The goal is to extend product life so that sales and profits do not decline. One strategy is called market modification. It means that marketing managers look for new users and market sections. Do you know, for example, that the backpacks that so many students carry today were originally designed for the military?
　　Market modification also means searching for increased usage among present customers or going for a different market, such as senior citizens. A marketer may re-position the product to appeal to new market sections.
　　Another product extension strategy is called product modification. It involves changing product quality, features, or style to attract new users or more usage from present users. American auto manufacturers are using quality improvement as one way to recapture（夺回） world markets. Note, also, how auto manufacturers once changed styles dramatically from year to year to keep demand from falling.

People do not analyze every problem they meet. Sometimes they try to remember a solution from the last time they had a 36 problem. They often accept the opinions or ideas of other people. Other times they begin to act without 37 ; they try to find a solution by trial and error(反复试验). 　38 , when all of these methods 39 , the person with a problem has to start analyzing. There are six 40 in analyzing a problem.

41 ，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 42 that there is a problem with the bicycle.

Next, the person must find out the problem. Before Sam can repair his bicycle, he must know why it does not work. For example, he must 43 the parts that are wrong.

Now the person must look for 44 that will make the problem clearer and lead to 45 solutions. For example, suppose Sam decides that his bicycle does not work because there is something wrong with the brakes. 　46 , he can look into his bicycle repair book and read about brakes, talk to his friends at the bike shop, or look at his brakes carefully.

After 47 the problem, the person should have 48 suggestions for a possible solution. Take Sam as an example 49 , his suggestions might be: tighten or loosen the brakes; buy new brakes and change the old ones.

In the end, one 50 seems to be the solution to the problem. Sometimes the

51 idea comes quite 52 because the thinker suddenly sees something new or sees something in a different way. Sam, for example, suddenly sees there is a piece of chewing gum (口香糖) stuck to a brake. He 53 hits on the solution to his problem: he must 54 the brake.

Finally the solution is 55 . Sam does it and finds his bicycle works perfectly. In short he has solved the problem.
