**Custom chip
A company, in a segmented field such as electricity meters, has customized a dedicated LCD chip, and by selling customized chips, its annual sales reach several hundred million.
Chip related:
1. The pin of the chip has been defined, which reduces the workload of the layout engineer
2. Because it is a custom chip, many useless functions are removed, and the cost is very low
3. In the field of liquid crystal display, the national standards of the industry do not change frequently
4. The original LCD market was a mixed bag. When this chip was launched, it formed a natural monopoly because of its low price and high quality. The manufacturers were satisfied and the R&D engineers were also satisfied.
In many segments, there are good opportunities for custom chips
**Corporate profits
The key lies in 2 points, utility and cost
To achieve the same utility, the cost is lower than other companies, it is a reasonable profit
Now the relationship between enterprises is getting closer and closer, and it is no longer a competition between individual companies, but a competition between supply chain systems
**Situational dissemination of knowledge
The most easily understood and interesting books are those with strong stories, such as "Xiaoqiang Promotion", "Key Chain", "Sophie's World".
Because the problem comes from reality, the situation includes the generation of the problem, the development of knowledge, and the change of knowledge.
**To choose the best suppliers and employees
On the surface, good suppliers and employees are expensive.
In fact, mediocre suppliers and employees not only cannot solve problems, but also create problems. This hidden cost is actually higher.
**Exchange gains and losses
A commodity, buy 1000 pieces, the unit price is 1 US dollar, the total is 1000 US dollars, equivalent to 7000 RMB
After a month, 1,000 units were sold at a unit price of $1.1, totaling $1,100. The exchange rate changed, equivalent to 6,900 RMB.
Calculated in U.S. dollars, you made a profit of $100, but in RMB, you lost 100 yuan instead.
When the financial system chooses the local currency, the above problems may occur
**True interest rate on funds
The interest is 40,000 yuan, and the loan is 12,000 yuan. Ant borrowed 12 installments of equal principal and interest, with 1080.23 repayments per installment, with a total repayment of 12,962.81 yuan, of which the principal was 12,000 and the interest was 962.81.
If you directly use 962.81/12000 to come to the conclusion that the annual interest rate is 8.023%, then you have become the old nose of the bank.
This is because the 12,962 yuan is not a one-time payment that you hold until the end of the year, but a monthly payment of 1,080 yuan per month.
This is the core theory that banks can make money by borrowing - money has time value, and the 1080 you repay in the first month is more "worth" than the 1080 you repay in the 12th month .
Through the XIRR function of Excel, the actual interest rate can be calculated to be about 15.6%.
365 days a year, the annual interest is 0.0004*365=14.6%
To repay in 12 installments, the formula for calculating the effective interest rate is (1 + 14.6%/12)^12 -1 = 15.6%.
**VAT and intermediate links
Each link needs to increase the value-added tax by 17%, so if a link is derived from the division of labor theory in a value system, this link must be more efficient than the original form by more than 17%, otherwise it will be a loss.
Example:
For example, in a furniture factory, planting trees, felling, making raw materials, processing, designing, and painting by themselves, it is equivalent to saving 17% of the value-added tax in each link.
If there is an external raw material supplier who wants to obtain the business of a furniture factory, it must ensure that the price is lower under the same quality, and there is still profit after paying the 17% value-added tax.
**Avoid vicious competition and require a strong third party to set rigid standards
The price war will not make profits, but will also reduce the quality. In many cases, consumers can only see the surface price, but cannot see the underlying quality changes. For example, two restaurants began to purchase from regular channels. Because of the price war, one of them purchased processed food first, and the other was forced to follow up due to cost pressure. At this time, they fell into a vicious circle, and only a strong third party , rigidly define standards and perform inspections in order to improve quality
**One of the keys to supply chain, balance fluctuations with the entire system
One of the difficulties in supply chain management is that demand changes frequently, and some industries are cyclical. Therefore, it is necessary to hold each other's shares and be prepared for danger, and the entire supply chain system can balance the fluctuations of the industry.
Just like the spring planting and autumn harvesting of crops, the period is one year. Occasionally, in the disaster year, the days will not pass. Therefore, a cycle of 3-5 years is used to prevent disasters.
**Progressive details
In the process of advancing a project, it is impossible to make detailed arrangements from the beginning, so a framework is generally formulated, and then a detailed plan is made for the current task. As the project continues, the whole project becomes more and more clear. .
**Systems and Trends
The most outstanding wise man among the savages, his mathematical knowledge is not as good as that of a middle school student in a modern society. This is the system advantage of a modern society.
A family is a system, a school is a system, an enterprise is a system, and a country is also a system
The influence of the system on people lies in the subtle influence, which is the influence of habits, ways of thinking, tools and other aspects.
- You can't think that bad habits are easier to develop than good habits. Habits are actually equal to people.
- Habits, tools, and ways of thinking that are more effective in maintaining the system are more likely to survive. Therefore, we see that the division of labor in society is becoming more and more refined, the functions of industry tools are becoming more and more powerful, and the way of thinking of people is becoming more and more good at grasping the essence of things.
**standardization
First-class enterprise as standard
Reason: Lower marginal cost
**Situational knowledge
Knowledge is not only content, but also includes structure, scope of application, etc., so the best way to spread knowledge is situational communication
The context includes the structure of knowledge, the source, the evolutionary path of knowledge, the scope of application, etc.
For example: an android SDK, which only gives code snippets, it is difficult for users to understand where to use it. If there is a complete small Demo, then everything is clear
** Ability to use leverage
When the foundation in all aspects is good, you can try to use leverage. There are practical examples of leverage in many fields: such as stock market allocation, developer competitions, and home loans.
**The default configuration is indispensable
Even if it is a Demo, it should be able to be used directly, and all configuration options should be filled with default values, otherwise the customer experience will be affected.
**Meaning of KPIs
In fact, it is a tool of management by objectives, which decomposes the overall goals of the company to each employee.
A lot of extra work that has positive significance for the company is not included in the KPI?
This is unavoidable. It can be considered that KPI is the main goal. Only when the main goal is qualified, will some secondary goals be completed. If something other than KPI is found, which is also very important, then it will be included in the KPI.
**First and second nature
The first property refers to the inherent and indivisible properties of objects: such as mass
The second quality refers to the ability of objects to act on human senses and make people feel: such as color, taste
**Existence is reasonable?
When Hegel said this, he did not mean that what exists is reasonable, but that what exists has a necessary reason for its existence.
For example, foot binding in ancient times, if Hegel’s existence is a reasonable explanation, the reason for its existence is that the nobles at that time had such a preference, which does not mean that foot binding is reasonable and reasonable.
** Veil of Ignorance
How can we do justice?
Suppose that before the birth, the naughty God blocked our sight with a curtain, everyone did not know the character to be born, and everyone discussed the design of the character together. At this time, everyone is more inclined to formulate the fairest system.
Rawls does not propose a specific method in The Theory of Justice, but proposes the above-mentioned idea, the veil of ignorance
The veil of ignorance can guarantee fairness, but it may not be the most beneficial. For example, two people divide oranges, and one person half, one of them eats the orange and throws away the peel, and the other makes tea with the orange peel and the orange flesh.
**extract
Invisible ideological bondage permeates everywhere in education in the ideological field
Traditional education keeps our minds tied in a net, and we like to think about things using these inherited theoretical perspectives. Most are in custom or popular opinion
A man who does things out of convention, does not make any choices. "By analogy, a person who thinks out of convention does not think anything.
**Study Rules
Visualization: Graphics are easier to remember than plain text
Use conversational and anthropomorphic styles: don't take it too seriously
Get learners to think more deeply (not just indoctrinate, but practice)
**The real learning ability is not how fast you learn, but the book just confirms your ideas
**Power, responsibility, and interests have institutional stability, but they still cannot guarantee certain stability, because people have subjective feelings of difference and enterprising spirit
**There are many things that books can teach you, but not everyone can do it. The gap in between is the ability to judge and make decisions in specific scenarios. It's like all high school students learn the same math textbook, and the scores they get are different.
