The guidelines for the "Important Experience" to arrange the priority order are based on the "important minority and triviality" principle. This principle is that the end of the 19th century and the Italian economist and sociologist Vivre, the Italian economist in the early 20th century. Its great idea is that in any particular group, important factors usually only account for a few, and unimportant factors account for most, so as long as they can control a minority factor that is important to control the global. After years of evolution, this principle has become a "80/20" principle known to today's management, that is, 80% of the value is from 20%, the rest of 20%. Value is from 80% of factors. For example, (1) 80% of sales are derived from 20% of customers; (2) 80% of the production amount is from 20% production; (3) 80% of the disease is 20% Employees occupying; (4) 80% of file usage is concentrated in 20% of files; (5) 80% of dishes are repeated 20% of dishes; (6) 80% of waste is 20% Place; (7) 80% of the file is concentrated in 20% of clothing; (8) 80% of TV times spend 20% of programs; (9) 80% of books are taken from bookshelves 20% of books; (10) 80% of the reading newspapers spend 20% of the layout; (11) 80% of the phone is from 20% of the speech; (12) 80% of the eating Go to 20% of restaurants; (13) 80% of discussion is taken from 20% of the 120% teacher's tutorial time being occupied by 20%. "80/20" principle An important inspiration for the time user of the manager is: Avoid spending time spending a trivial number, because you spend 80% of the time, you can only get 20% Effect: You should spend time on important minority issues, because you have a cost of 20%, you can get 80% effectiveness. "80/20" principle is extremely widely used in business management, and the examples are now clarified. Example 1: On inventory management, there is a so-called "ABC Classification Law". This classification method is divided into three categories A, B, and C in stock. Class A representative "important minority", this type of inventory is small. They should have to pay attention to the best inventory management, including the most complete record, the most abundant order, and the most careful storage. Class C storage refers to "Trivial Most". This type of inventory is low, such as folders, staple, paper bags, envelopes, stamps, etc. belong to this class. For this class, there is no need to have any inventory management, because if this management is applied, the cost of spend can exceed the value of these items itself. So in general, when responsible for the stock of the stock, it is necessary to add. Class B is referring to the goods between Class C and Class C. Usually the inventory management of such goods can be carried out in mechanization, i.e., when the number of inventories drops to a certain number, the company should automatically add inventory. Example 2: An insurance company classifies the size of its customer transaction volume in accidental cases, and it is found that almost 90% of the total turnover is less than 10% of the major customers. This discovery prompted the company to produce huge changes to the business policies of the size of the size - concentrated time to serve a few major customers. As a result, the company's general business and profits have increased trends. Example III: A company has asked all levels to point out the factors that hinder the company's profit growth, with 37 items. Due to too many projects, it is impossible to solve it, so the company's leadership requires all class supervisors to arrange these thirty-seven factors in order of its importance, and finally discovering the first five factors to hinder the growth of profit growth.
Example 4: The President of a watch company found that in the many watt models produced by the company, about one-third of the model sales only account for 4% of total sales, so it decided to stop the manufacture of these models. The company's profits gradually increased in the next six months. Example 5: A departmental supervisor is only working three or four hours a day, followed by the doctor. He was very surprised to find that these three, four hours have done in terms of quality and quantity and the past a day, and nine bells have almost no two. The only explanation he can provide is that since his work time is forced to shorten, he has to spend it in the most important work, which may be the main reason why he has maintained working performance and improving work efficiency. Example 6: Traditional refrigerators are in the upper end, and the refrigerator is located at the lower end. When you use a freezer, you can maintain a standing posture, but when you use a refrigerator, it is often not possible. Since the use of the freezer is only 20%, the use of the refrigerator is as high as 80%, so that many housewives often have too many times when using the refrigerator. Solid back pain. Based on this, a home appliance company is placed on the upper end of the refrigerator and places the freezer in the lower end. This new type of refrigerator can reduce the number of times when using it. The design of this new product is based on "80/20 principle".
