There is a math problem: 90% × 90% × 90% =? The result is 59%.
What does this equation mean if the simple mathematical meaning is put aside? Growing up, we all know that 60 points is the passing line, 100 seems to be more difficult, and 90 points is a score that we can be proud of. The same is true at work. Many people think that "doing 60% of the work is too dangerous and the company will fire you;" It is too hard and unrealistic to achieve 100%; It's good to do 90% of your work. "This statement seems reasonable, but the working process is composed of a series of subtle links, each of which is based on the previous link, and the interaction between links is based on multiplication, not simple percentage superposition. At the end of a series of interlocking processes, the final result of "very good" 90 points may be 59 points-failing points, which is the process control effect.
An intensive modern business process needs to go through many links such as conception, planning, design, discussion, modification, implementation, feedback and correction. If you can't take every link seriously, feedback and correct it in time, and don't devote yourself to the perfection of every link, but take it for granted that "the result will not be too great", then the final outcome may be that you have achieved 90% in this link and 90% in the next link. After five links, your job performance is not 90% on average, but 59%-one will be eliminated by the fierce competition environment. In some cases, it may be lower than this score or even become negative!
At this time, if we go back to "overhaul" according to the standard of 100%, it may mean that the whole project and the whole project need to be "reinvented", which means that time and resources are wasted, efficiency is low, and opportunities are missed, which means that previous efforts are in vain. 90% × 90% × 90 %× 90% × 90% = 59%. The significance of this simple equation beyond mathematics is that the realization process cannot be discounted.
"25 o" law
Gillard, a famous American salesman, found in her long-term work that behind every customer, there are generally 250 relatives and friends, and these people will have the same relationship. He called this phenomenon "250" law. Offending a customer will lose dozens, hundreds or even more potential customers, on the contrary, it will have the same positive effect. It is especially important to be kind to picky customers. An American furniture company stipulates that all goods purchased in this store can be returned within six months and replaced within two years if they are not satisfied.
One day, an old woman came to a shop in the company, holding a worn umbrella tube for the hall, saying that she didn't like it and insisted on returning it. This umbrella tube has been used for seven years, so it can only be thrown into the trash can. It stands to reason that such unreasonable demands can be completely ignored, but after careful consideration, the store manager decided to exchange the goods. You will ask, isn't this encouraging some people to take advantage? In fact, the manager of this store knows very well that this kind of "thorny" customers are very few, but they are very influential.
If we don't solve their problems properly, they are likely to spread the truth everywhere and make people who don't know the truth doubt the credibility of the company; On the contrary, if their requirements are met if possible, they may also provide their own opinions and bring more new customers to the company. This is Gillard's "250" law.
Jewish "cosmic law"
Jews have a long history of 5000 years, and their splendid culture has shone all over the world, which also contains many mysterious things. "78∶22" is a mysterious law handed down from generation to generation by Jews scattered all over the world-the law of the universe. "The laws of the universe", including China's Taiji diagram and Taoist gossip, is an understanding of the objective world.
Taiji Diagram shows that the world is made up of Yin and Yang, while the Jewish "cosmic law" holds that everything in the world exists in a ratio of 78∶22. For example, the air composition on the earth is: the ratio of nitrogen to oxygen is 78: 22; The ratio of water to other substances in our body is also 78: 22; Jews do business and like to analyze the proportion of each business according to 78: 22. For example, are there more "lenders" or "borrowers" in the world? The average person answers: "There are many borrowers". But Jews have long found that "lenders" are much higher than "borrowers", with a ratio of 78: 22. Quite simply, banks survive by borrowing a lot of money from "lenders" and then lending it to a few "borrowers".
In the eyes of Jews, 78% of the world's wealth is always in the hands of a few rich people, while 78% of ordinary people only hold 22% of the wealth. It is also for this reason that Jews despise "small profits but quick turnover" and pursue high profits and quick turnover. Jews always give people a confident look when they do things, because they think that only 22% people will master this "law" forever. Because all ethnic groups consider themselves superior and exclusive, this law has become a Jewish patent.
Horse fly effect
One day Henry, editor-in-chief of The New York Times? Raymont came to see Lincoln. When talking about Chase's enthusiastic pursuit of the presidency, Lincoln told him a short story: "Raymont, didn't you grow up in the countryside?" Then you must know what a horsefly is. Once, my brother and I cultivated land on a farm in my hometown of Kentucky. I rode a horse, and he helped plow the fields. The horse was lazy, but for a time it ran so fast in the field that even my long legs could not keep up. On the ground, I found a Malaysian fly biting it, so I didn't knock it down. My brother asked me why I had to abort. I replied that I couldn't bear to be bitten like that. My brother said, "Oh, this guy made the horse run!" " "Then Lincoln said meaningfully," If a horse fly named "Presidential Desire 8" is biting Mr. Chase now, as long as it can keep Chase running, I don't want to shoot. "
Parkinson's law
The famous British historian Northgood? Through long-term investigation and study, Parkinson wrote a book called Parkinson's Law. In his book, he explained the reasons and consequences of the expansion of institutional personnel: an incompetent official may have three ways out. The first is to apply for resignation and give your seat to someone who has the ability; The second is to let a capable person help him with his work; The third is to appoint two people lower than themselves as assistants. This first way is absolutely impossible, because many rights will be lost; You can't go the second way, because that capable person will become your opponent; It seems that only the third way is the most suitable.
So, two mediocre assistants share his work, and he gives orders from above. They will not pose a threat to their rights. Since both assistants are incompetent, find yourself two incompetent assistants from top to bottom. By analogy, a leadership system is formed, which is bloated, overstaffed, wrangling with each other and inefficient.
The Butterfly Effect
The so-called "butterfly effect" is used to describe the complexity of causality. It is said that a butterfly in South America flapped its wings and developed along the causal chain, which eventually triggered a storm in the northern hemisphere. The storm caused by butterfly wings may be exaggerated, but it does exist in life. A small incident caused a chain reaction, which spread more and more and produced unexpected results.
Law of 8020
There is a famous 80/20 law in the field of management, which says that usually 80% of an enterprise's profits come from its 20% projects; This 80/20 law has been extended again and again.
Economists say that 20% of people hold 80% of wealth.
Psychologists say that 20% of people have 80% of human wisdom and stand out from the crowd at birth. There is no absolute fairness in this world.
20% people enjoy 80% love in the world, and even handle 80% divorce procedures in the world. These 20% people are always loving and being loved, and the remaining 80% people have to find and pursue hard;
20% people have experienced 80% joys and sorrows in life, 80% people have experienced 80% wonderful and ups and downs, and 80% are more likely to write in plain days;
20% of people can achieve 80% of their wishes; And 80% of people can only achieve 20% of their wishes;
20% people account for 80% of the world's interests; Leave 20% of the poor and let the 80% break their heads and grab a ball; Is to invite a meal, 20% of the guests ate 80% of the good food. Don't believe it? Please have a try.
I was on the run last week. Besides coping with my own workload, I was forced to do a lot of extra work. I was told at the top of my lungs that in any unit, 20% people do 80% of the work. 80% people are idle and leisurely deal with the remaining 20%. I immediately thought, why am I always on the wrong side? When I want to be 20%, I am often the 80%; And when I finally achieved 80%, I had to do 20%! Unfortunately, that's how the 80/20 law works on a person.
This is not a question of absolute fairness, it is absolutely unfair! When it's their turn, the law of 80/20 usually goes like this: 20% of people have fallen 80% of mildew, or 80% of people craned their necks to look at other people's 20% of good luck, feeling empty and sad. When I thought like this, I suddenly understood the essence of the 80/20 law. In fact, the wise ancients in China expressed it in another sentence, saying that life is often unsatisfactory.
How much does a glass weigh?
How much does a plastic cup weigh? 13g. But it is such a trivial matter, but Air France spared no effort in energy conservation and emission reduction:13g was reduced to 9.5g.. This subtle "slimming" of 3.5 grams was later extended to all flights of all French airlines. For a plane with huge fuel consumption, it seems insignificant to reduce the weight of a water cup by 3.5 grams. However, in the eyes of managers, the role of small water cups should not be underestimated-according to the calculation of French experts, the whole company can "slim down" and emit 20 tons of carbon dioxide less a year because of small water cups. The details show the shrewdness and foresight of the management.
broken windows theory
Many years ago, Zhan Badou, a psychologist at Stanford University in the United States, did an experiment. He found two identical cars, put one in a middle-class neighborhood in Palo Alto and parked the other in a relatively messy Bronx neighborhood. The car parked in the Bronx, he took off the license plate and opened the roof. As a result, the car was stolen within a day, and the one left in Palo Alto was left unattended for a week. Later, Zhan Badou knocked a big hole in the car glass with a hammer. And the result? After only a few hours, it was gone.
Based on this experiment, political scientist Wilson and criminologist Karin put forward "broken window theory". The theory is that if someone breaks the window glass of a building and this window can't be repaired in time, then others may be indulged by some hints to break more window glass. Over time, these broken windows give people a sense of disorder. Therefore, in this insensitive atmosphere, crime will breed.
Stamp theorem
A king brought a monkey to accompany him. Monkeys are naturally clever and soon get the king's love. People around the king also respect it. The king believed and loved monkeys very much, and even let them hold their own swords. One day, the king went to visit a garden with only monkeys. Tired of playing, the king said to the monkey, "I want to sleep here for a while." If someone wants to hurt me, you must try your best to protect me. "The bees smelled the flowers, flew over and landed on the king's head. The monkey thought, "How dare this guy sting the king in front of my eyes!" " "Draw your sword and cut it like a bee. As a result, the king's head was cut off The reason for the tragedy is that the "king", as a manager, chose the wrong authorized object. Successful business leaders are not only masters of authorization, but also masters of power control. This is the stamp theorem.
