How to solve the problem?

Life is a process of constantly creating and solving problems. Some problems can be solved quickly, while more problems have never been found in our lives. In order to make up for the activities when buying books, I recommend adding a book, "Is your light on?" ",it turns out that the original choice is so wise! The author is the famous Gerald M. Weinberg, 1997. Because of his outstanding contribution in the field of software, he was selected as one of the first five members by the Computer Hall of Fame of the American Computer Museum. You know, including Bill Gates, only 20 members have been elected to the Hall of Fame so far. " Is your light on? "Is a book to help you solve the problem. The whole book is very thin, only 100 pages. It is not obscure theoretical knowledge, but through six themes and more than ten stories, it helps you find the key to solving the problem.

The opening of the book tells the story of the postman Peter repairing the elevator. In the center of gotham city's financial district, stands the 73-story magnificent Lei Long Tower. The building has just been completed, but there is a fatal problem: the elevator system of the building is imperfect, and the running speed is far lower than the normal speed, which seriously affects the daily travel of employees. Seeing that the problem has not been alleviated for a long time, the tenants of Lei Long Building proposed that if the elevator service was not improved as soon as possible, they would withdraw their rents and move out of Lei Long Building. When the building managers understood the problem, they sent Peter to solve it. Peter came up with his solution: put a mirror in the waiting area of each elevator. Because of vanity, people waiting for the elevator will pretend to be calm even if they are anxious again, and tidy up their clothes in front of the mirror from time to time. Therefore, the voice of complaints was alleviated in a short time, and the building manager happily patted Peter on the shoulder and gave him an appropriate reward. However, the good times did not last long, and the speed of the elevator was still very slow. Some impatient people began to destroy and doodle on the mirror. In order to solve this problem, Peter came up with a way, that is, simply put some crayons and drawing boards to give people who want to draw a picture a place to vent. The problem of mirror damage was temporarily alleviated, and the building manager rewarded Peter again. As you expected, more and more graffiti makes some people who don't like it feel sick, and they plan to complain to the relevant departments. In this way, for nearly a year, tenants spent their time in constant complaints, and Peter struggled to solve one problem after another. It was not until the first anniversary of the building that the elevator company came to the door for maintenance normally. Soon, they found a mouse in the main control box. In order to escape, the trapped mouse bit off one of the main control relays. Therefore, the elevator power is insufficient, and the running speed naturally cannot reach the normal standard. After finding the problem, the elevator maintenance worker replaced the main control relay, and the running speed reached the expected standard. Since then, the problem of slow elevator operation in Lei Long Building has been completely solved.

From finding the elevator running slowly to solving the problem, the postman Peter put a mirror first, and then put crayons and drawing boards. Instead of solving the problem, it became more and more troublesome. The installation of mirrors has alleviated the problem to some extent, but the fundamental problem of slow elevator operation has not been effectively solved, so the problems will accumulate more and more. When I saw Peter solve the complaint problem with a mirror, I remembered a famous law-Occam's razor law. It means that when you have two competing theories that can reach the same conclusion, the simple one is better. Japan's largest cosmetics company received a customer complaint that the soap box it bought was empty. So in order to prevent this from happening again on the production line, engineers tried their best to invent an X-ray monitor, which can see through every soap box that arrived. The same problem happened in another small company. Their solution is to buy a high-power industrial electric fan to blow every soap box, and all the empty boxes without soap are blown away. Do the same thing in two completely different ways. Obviously, the second one is more convenient. In Occam's razor law, the two companies do not do the same thing, but they both solve the fundamental problem that there is no soap in the soap box, so the simpler the method, the more commendable it is. On the other hand, Peter's solution to the slow running speed of the elevator seems to ease the complaint, but neither of them touches the core of the problem and will naturally end in failure. This gives us a revelation: should we solve the problem immediately? The answer is no, when we don't understand the root of the problem and solve it immediately, most of the solutions we find are just adding to the block. Finding the essence of all problems is also very simple, that is, finding the difference between what you expect and what you have experienced. The difference between the expected speed and the actual speed of the elevator in Lei Long Building is the root of the problem, and how to solve the slow elevator speed is the core of our concern. Therefore, when we encounter problems, don't rush to deal with them immediately. Tracing back to the source, finding the source of the problem and understanding the essence of the problem are the key to solving the problem.

Why is the title "Is your light on? This actually comes from the story in chapter 13 of the book Light at the End of the Tunnel. An engineer completed a tunnel. In order to ensure safety, the engineer made a warning sign outside the tunnel entrance-note: there is a tunnel ahead, please turn on the headlights. Just like driving on the highway, sometimes you turn on the headlights when you cross the tunnel and forget to turn them off when you leave the tunnel. Not far from the tunnel in the story is a scenic spot. People parked their cars and went camping with great interest. It was not until the next day that they found the light on. Because they are all powered cars, on average, more than a dozen cars can't start every day because the battery is dead. In the end, I can only trouble the police to come over and charge or tow away the car, which leads to a bad experience for people who come here to travel. So who does this problem belong to? Since the tunnel is designed by tunnel engineers, people's first reaction is them. Therefore, they considered the following solutions:

1. Setting up a "Please turn off the lights" sign at the exit of the tunnel will confuse drivers who drive at night.

2. The rest area provides charging service free of charge, which is expensive and the maintenance period is too long.

3. Hang more obvious warning signs at the tunnel exit:

If it is daytime, if the light is on, please turn off the light;

If it is night, if the light is off, please turn on the light;

If it is daytime, if the light is off, it will always be off;

If it is night, if the light is on, it will always be on.

Think about it. What would you think if you saw such a sign on the road? Simplicity is not sex. Say it. Obviously, such a solution is unreasonable. Since the problem lies in forgetting to turn off the lights in time, the focus of the solution should be on turning off the lights in time. So, who should solve this problem? The answer is the driver. Because even the best engineer can't turn off the lights in time instead of the driver, all he can do is to remind him. Although the third scheme can also play a certain role, it is not effective because the content is too long. Finally, the tunnel engineer put a sign at the tunnel exit: "Is your light still on?" The simple seven words effectively reminded drivers to turn off the lights in time, and the root of the problem was effectively solved. If the engineer chooses the second option at first, he will bypass the essence of the problem like Peter the postman, and instead create many new problems. Seeing this, has your lamp of wisdom started to light up? Next time you encounter a problem, don't rush to deal with it. First, calmly analyze the essence of the problem and clarify the source of the problem. The book is more about other thinking about the problem, such as where did the problem come from? Do we really want to solve the problem?
