I want to express business administration with mathematical formulas. For now, let's create the 4Ps of the marketing mix into an equation of four variables. by Nada 20231029

Hello. This is Nada from Seito Medical School. Production management is the management science of the manufacturing industry.

Manufacturing business (manufacturing) follows the flow of "product development," "production," and "sales." "Product development" involves discussions about how to make products, such as product planning, design, and prototyping. "Production" is the stage in which ideas compiled through product development are produced into products. Everything that includes "sales" is collectively called "manufacturing."

A company's competitiveness can be said to be the source of being chosen by customers in the market and continuing to generate profits. One of the competitive strengths of a company is price. When it comes to pricing, the most important thing is to be in the black, that is, to make a profit, and no matter what kind of product you sell, it is important to set prices so that you can make a profit.

In business administration, there is a concept called 4Ps. One of them is the price that we just talked about. Furthermore, there are products, distribution and sales (place), and sales promotion (promotion). These four acronyms are called the 4Ps or marketing mix. Is it something like advertising good products at low prices and using a sophisticated sales network to inform customers? QCD supports the 4Ps that form the basis of competitiveness from below. The 4Ps or marketing mix are standards that are visible to customers, but QCD is a standard that is not directly visible to customers.

QCD is an acronym for three keywords: quality, cost, and delivery, and is value that is not directly visible to consumers. In other words, we produce high-quality products that meet your needs at low manufacturing costs and on time.

In addition to this, what I learned this time was also the discussion of the combination type and the assembly type. The mating type is a method of assembling multiple parts in complex combinations, similar to traditional automobiles. Since each part of the mating type is a dedicated part, it is not realistic to replace it with parts from other manufacturers.

On the other hand, assembled type products can be interchanged even if they are made by different manufacturers, such as in computers and electric cars, where parts are standardized within the industry. However, desktop computers, so-called fixed computers that cannot be carried around, are assembled-type computers, but one product, such as a notebook computer, that is made using parts that are difficult to replace is a assembled-type computer.

As we have seen so far, management theory is based on what seems obvious at first glance. For example, the 4Ps can be said to be the competitiveness of a product, such as price, product, sales channel, and advertising. Here, I can evaluate the 4Ps as competitiveness related to products, and tactical competitiveness such as product price, product itself, product sales channels, and product advertising.

On the other hand, I think QCD can be viewed not only from the competitiveness of the product but also from the perspective of the company. A company's quality control, a company's manufacturing costs, delivery times as a corporate structure, etc. For example, in Japan, where I live, the value system was to provide high-quality products at low prices, and we provided cheap and high-quality products.

Now, I would like to talk about Toyota Motor Corporation. Toyota Motor Corporation is a well-known company representing Japan. According to my memory, I may be wrong, but I think annual car sales were about 10 million units. This level of sales makes us one of the top companies in the world.

Toyota Motor Corporation is now under pressure to manufacture non-gasoline vehicles such as electric cars and hydrogen cars. One of the points is regarding the global environment. There were famous conferences on reducing CO2 emissions in Kyoto and Paris, and people were criticizing gasoline-powered cars for increasing their CO2 emissions. Therefore, not only Toyota but other car companies around the world began manufacturing electric cars that do not emit gas in order to overcome the regulations imposed by the Kyoto and Paris conferences. In Japan, we were good at developing complex, assembled cars, but in America and other countries, assembly-type products that combine unified parts, such as electric cars, are gaining an advantage.

Toyota's 4Ps and QCD have been at the top level in the world and have been doing business up until now, but the competitive environment will change completely with just one environmental regulation. We have produced a large number of hybrid-type automobiles and must have accumulated many various patents and know-how, but the 4Ps and QCD can easily be destroyed simply because they are bad for the environment.

However, in the case of Toyota, it has been manufacturing complex products that are assembled together, so it shouldn't be difficult to manufacture an electric car that just requires assembling simple parts. Rather, changes in the era using artificial intelligence software, such as self-driving cars, have the potential to be more difficult.

Now, I would like to introduce mathematical formulas to business administration.

I think the 4P's are "price", "product", "market", and "sales promotion". However, when the price of a certain product goes up, if the price goes up to make the product better, then there is a positive correlation: if the price goes up, the product goes up. On the other hand, when the price goes up, if manufacturing costs remain constant, sales channels and sales promotions may increase, but since manufacturing costs have increased, if the price increases, the budget for sales channels and sales promotions may decrease. I don't know. This is a negative correlation as sales channels and promotions go down.

For example, if price 1 = product 1, sales channel 1 = sales promotion 1, then

Price/sales promotion = product/sales channel.

Here, if advertising costs are multiplied by 1.2 for sales promotion, since the price is constant, product / sales channel = 1 / 1.2, 1.2x product = 1x sales channel = 1 x 1, and the product will be 0.833 times more expensive. In other words, it will be 20% worse, or 1.2x product = 1.2 x 1 = 1x sales channel, and the balance will be achieved by improving sales channel by 20%. I would like to think about what this means in the future. However, this formula may be wrong from the very beginning, so don't worry.

Furthermore, it may be interesting to turn QCD into a mathematical formula and consider its relationship with the 4Ps. If you have time, you might want to give it some thought. Great discovery! ! There may be... See you soon.

Study with an eye to the next few years. Current knowledge is based on knowledge learned several years ago. by Nada 20231029

Hello. This is Nada from Seito Medical School. What are you currently studying? I think it is necessary to plan what you will study many years in advance. What you are studying now is not knowledge that you will use in your current job, but rather knowledge that you will use in your job several years from now. On the other hand, I can say that the knowledge I learned several years ago is useful in my current job.

Key points this time : ① It is necessary to update new knowledge every day. ②The knowledge that is useful now is based on what I learned many years ago. ③We will act with an eye toward the future several years in advance .

New knowledge needs to be updated daily. The type of career you want to build varies from person to person, and the learning you do will change depending on your career direction. Even in the blog I am currently writing, this type of dictation writing style is based on the blog I was writing 4 or 5 years ago.

I started a blog about 4 years ago, but it didn't last long and I gave up after 3 months. However, since then I have updated my blog on a regular basis and now have about 170 articles. For the first three months, I desperately updated long articles every day, but just before I felt like I was about to discover some kind of superpower, I gave up.

If I had continued to update my blog for four years now, I might have been able to fly in the sky without even getting on a plane. I did something unfortunate. However, the experience I had back then still applies to me, and I didn't feel any discomfort when I started writing for the first time in a while, and I was in a state where I could easily mass-produce articles like those from the past. After all, experience of doing something is important, and in a sense, there is some validity to job offers that refuse applicants with no experience.

Currently, I am studying hard about business and medicine, but I would like to prioritize business first. On top of that, in terms of medicine, I would like to work on effective treatment methods, such as methods that include anti-aging. Well, I'm an amateur who didn't even go to medical school, but amateurs have their own way of fighting.

My hope would be to eventually publish a paper in a medical journal, such as Nature. I don't get many benefits from it, just benefits like honor.

Well, up to this point I'm just an amateur researcher, but I'm also expanding my research into various things as an amateur, so I'd like to publish the results of my research on this blog.

In a sense, it is important to say, ``Study with an eye to the future several years in advance.The knowledge you have now is based on the knowledge you learned several years ago.'' Just like a student studying for a test, it can be said to be studying for a career several years in the future. Where do you want to be in the next few years? It would be great if you could always hold on to that vision and start studying to prepare for it.

Even when studying for a qualification, if it is a difficult qualification, study ahead several years in advance. Just as students study for one or two years ahead, it would be great if working adults could continue studying with an eye on five or ten years ahead. That's why I also want to become a well-known big name in 5 or 10 years. First of all, I plan to study hard for three years, so it would be great if I could share the results of my studies on this blog.

I will be in my late 30s in three years. This will be an accident site where many events will occur in various ways, so I would like to keep an eye on what will happen three years from now. Everyone, please start making plans and starting things by looking ahead to the next few years. Depending on your efforts, something like that may come true in a few years. See you soon.

The act of hurting something, such as self-harm, may be a self-cleansing action that restores something that has been lost. by Nada 20231027

Hello. This is Nada from Seito Medical School. There are many mysterious phenomena in the world. For example, if you are infected with a virus, you will develop a fever. It may seem like a disadvantage that it increases your fever and makes you feel sick, but it actually has a self-purifying effect by getting rid of viruses. There are many similar events in the medical world. For example, self-harm. It's a disease that causes you to harm yourself. The reason why people self-harm is because they want to restore something that was originally in their body, and they can't stop doing it. That something lost may be spiritual, or it may be related to the mechanics of the body. I also have a habit of biting my nails, but it can also be analyzed that I do this because I want to restore something. I don't know if what was lost has something to do with the claws or the act of biting. The only thing I can say is that if we can regain something that was lost, there is a high possibility that self-harm will stop.

I was also able to temporarily cure my nail biting habit. If I always wear a mask, my nails don't come into contact with my mouth, so I can no longer physically bite my nails. However, after that, when I relaxed and stopped wearing the mask, I started biting my nails again. What I lost probably hasn't been restored, so I guess my nail-biting habit never really got better. There are probably a certain number of people in this world who commit suicide or self-harm. It is not known whether the cause is psychological or physical. However, if we think of hurting something as a self-cleansing action of trying to restore something, we may be able to see the causes of many self-harm acts. See you soon.

Let the boss win. Maybe this is the only way to quickly get promoted and become an excellent employee...? by Nada 20231027

Hello. This is Nada from Seito Medical School. This time's theme is about business. eh? Is business like selling expensive pots? that's right. We don't have expensive pressure points as products, but instead we have products called information. Maybe it's an information product... yes. We would like to provide you with a plan that suits you.

If you have a boss, which would you rather have: a plan that lets your boss win or a plan that doesn't let your boss win? I think this is a major turning point in the life of a businessman. If you are a businessman, you belong to some kind of organization, and of course there is a boss even in non-profit organizations such as NPOs (non-profit organizations) and NGOs (non-governmental organizations). Nowadays, there are young people who don't want to get promoted, so the responsibility of the boss is very important.

Regarding the previous question, should you let your boss win or not? I would recommend a plan that lets your boss win. This is because if a boss is promoted, he or she will try to take his or her superior or favorite subordinates with him or her. What you can do to achieve this is to polish your own leather shoes and hone your skills to help your boss win. For me, the quickest way to get promoted is to hone your own skills and use those skills to improve your boss's performance.

If you were your boss, what kind of subordinate would you want to motivate? He is very serious, and even if he is clumsy, no boss would be harsh on a subordinate who desperately tries to make him win. This also applies to me, but I can say that you need to make an effort to win over your superiors in a variety of areas, including not only your relationship with your boss at the company, but also your relationship with customers, your relationship with doctors, and so on. Even if the other person is in a higher position, I sometimes continue to whine until I get it, so I often ask myself why things came to be like that, what my boss is thinking right now, and how I feel as a subordinate. I think a person who can instantly guess what they should do is a good person.

There are times when I get frustrated when my parents don't buy me sweets, but I personally wish I could at least ask my parents why they can't buy me sweets, as far as a child can think. , I can say that I have grown. Due to the relationship between boss and subordinate, we are friends who are walking the same path. Since that friend is giving you instructions, it must be important to you as well. Do you have a good relationship with your boss? It would be a waste if the relationship ended up with one person dominating the other.

First, listen to your boss. If you ask your boss a question, he or she will tell you why he or she thinks that way. Let your boss win. If you approach things with that mindset, your boss might take you to a higher level. See you soon.

Use a formula with a difference of twice on both sides. It would be sad if the boss of that large company was paid more than twice as much. by Nada 20231024

Hello. This is Nada from Seito Medical School. There are various combinations of calculations for A=B and C=D. It's a restaurant that has so many combinations that it's hard to order.

Adding A=B and C=D gives A+C=B+D. If we subtract A=B and C=D, we get AC=BD. When multiplied, AC=BD or AD=BC. When divided, A/C=B/D.

If (A/B)=(C/D) is A=1, B=3, C=2, D=6, (1/3)=(2/6) is also correct, but C is twice as much as A, and D is twice as much as B. In other words, (2/2) x (1/3) = (2/6).

In this state, if (A/B) = (C/D), we can derive A=C between the numerators and B=D between the denominators. However, please note that the correct answer is Ax2=C, which means 1×2=2. Regarding B=D, Bx2=D and 3×2=6.

However, here we purposely use an equation with a difference of two times on both sides. It would be sad if the boss of that large company was paid more than twice as much. It would have been twice as good...

First, add both sides of A=C and B=D. A+B=C+D. This will look like this: A+B=1+3=4, C+D=2+6=8. Therefore, the state where there is a difference of 2 times on both sides will be preserved. Of course, even if AB=CD, 1×3=2×6 and 3=12, so the difference is 4 times. Multiplying the 2x difference twice will give you a 4x difference.

So far, things are good, but from here on out, we are currently researching. Sample below.

(A+B) x D=(C+D) x B

(1+3) x 6 = (2+6) x 3

The above was a sample. Have a nice day tomorrow. See you soon.

If a person whose contribution was positive becomes a negative contribution, it will cause double damage by Nada 20231023

Hello. This is Nada from Seito Medical School. I want to express business administration using mathematical formulas. For example, there are theories about students' study time. For students, input time is time for studying, and output time is time for solving problems. One thing to keep in mind here is that once words are spoken, they cannot be taken back. Regarding this, I would like to write another article on the theme of turning a crisis into an opportunity.

Well, I don't think there is such a thing as wasted time. Even the time you spend absentmindedly, which may seem like a waste, may be necessary time to clear your head. On top of that, let's make an assumption that, conversely, there is no time to waste. Time spent inputting knowledge is wasting time that could be used to do something.

This is a double waste. In other words, wasted input time increases skill by +0. In other words, there is nothing to be gained. On top of that, time is consumed, so the time becomes -α (minus alpha).

Even if there is time for all inputs, it is divided into time for wasted input and time for necessary input. In other words,

Time for all inputs TI (total input)

= time for wasted inputs nI (not inputs) + time for necessary inputs I (inputs)

,

TI = nI + I = inefficiency

Here, as I mentioned earlier, if the required work time is wt (work time), then

wt = nI

. In this example, wt would solve the problem. Assign wt to nI of TI.

TI = Tw (total working) = wt + I = efficient

. Here, there is also a way of thinking that nI is -nI. Think about why you do it. Using this kind of thinking, it would be possible to replace business administration or liberal arts subjects with mathematical formulas.

Finally, apply actual numbers to explain how wasted input time is doubly wasted.

TI=8

, which means 8 hours of input. Of these, 6 hours are considered necessary input, and 2 hours are considered wasteful input.

TI = nI + I = 2 + 6

Since 2 hours are wasted, the result of work is 6 hours.

Let's turn this wasted input into necessary work time wt.

wt = 2

TI = wt + I = 2 + 6 = 8The

work result is 8 hours, but compared to when the work result was 6 hours, when the work result was 6 hours, the work result was 2 hours. I don't have much time and I wasted 2 hours. That's two hours less, both in terms of work results and wasted time.

The idea here may be a little difficult. It might be a good idea to consider that 2 hours of wasted input will take away 2 hours of your physical strength. I have to rest for another two hours to recover my strength. If we end up with a minus 2 hours instead of zero when we should have added 2 hours, then (-2) + (-2) = -4, and we can say that we have wasted 4 hours. If something that was originally a plus becomes a minus, the portion that can be considered profit will be greatly burdened.

For example, if an employee who used to be an asset at a company becomes a window employee who only receives a salary, then what used to be a plus has now become a minus, resulting in double damage. If this employee were to contribute even just a small amount to the company's sales and make a positive difference, it would no longer be double damage. In other words, it will be a single loss.

In business administration, by expressing things in mathematical formulas like this, we may be able to see things that were previously invisible. Words that come out of your mouth cannot be taken back. I guess I also need to take responsibility for the content of this article. have a nice day. See you soon.

In economics, which is more important: quantity adjustment or price adjustment? For products that are selling well, you can freely adjust the quantity and price by Nada 20231022

Hello. This is Nada from Seito Medical School. This time, we will be talking about quantity adjustment and price adjustment, which have different perspectives in macroeconomics and microeconomics. When a lot of things are sold, the difference is whether to increase the quantity while keeping the price the same, or to raise the price and seek more profits.

I may talk a little passionately about this quantity adjustment and price adjustment this time. Or maybe he will release an epic fantasy story after Hotaru no Hikari. For those times, grab a cup of coffee and have a good time. yo, Chekeracho! !

One question in economics is whether quantity adjustment or price adjustment is better. This also has long-term and short-term implications. In the short term, when sales of goods increase in the market, the cost of goods includes things that cannot be easily lowered or increased, such as wages, so factories respond by increasing production. This is what is called a quantity adjustment. On the other hand, in the long term, it can be said to be a price adjustment because the expenses such as wages, which are the main factors in prices, are adjusted over a long period of time in response to market movements.

The field of economics that focuses on quantitative adjustment and focuses on the short term is called macroeconomics. On the other hand, the field of economics that focuses on price adjustment and the long term is called microeconomics. Keynes, the founder of macroeconomics, famously said, ``In the long run, everyone is dead.'' Adjusting prices is difficult. Dear readers, the prices of things are rising due to the recent price rush (October 2023). When the price of this item increases, it is called inflation.

So, is the current period of long-term price adjustment?The current inflation can be said to be caused by a rise in the cost of producing goods, which is called a cost push. One reason is that oil prices are rising due to the conflict in Ukraine. Of course, the economy is not bad, so it can be said that there is some demand inflation where consumption leads to consumption.

If the product sells, increase the price. If the product doesn't sell, lower the price. This is the idea of ​​general equilibrium, but it's not quite the opposite; if a product sells, lower the price and increase sales. You can see that the idea that if a product does not sell, raise the price and increase profits is not wrong. However, since economics emphasizes a balanced and stable economy such as general equilibrium, general equilibrium theory can be said to be the more mainstream way of thinking.

The economics that focuses on this microscopic general equilibrium theory is called the ``new classical'' or ``monetarist'' economics. By the way, macroeconomics is called "Keynesian".

Now, onto the main topic. Regarding my opinion, whether quantity adjustment or price adjustment is better, I think it would be good to have the option of trying both. For example, what about a plan like this? When a product sells, the price is lowered through price adjustment. A fall in the price of a selling product means a further increase in market share and an increase in total profit. Here, profit is sales - expenses = profit. Lowering the price will reduce the profit per product, but it is assumed that it is possible to increase the overall profit while maintaining the profit rate by adjusting the quantity. In other words, you can improve your company's performance by adjusting quantities and prices on a case-by-case basis.

However, in the short term, prices are fixed, so I think it is too simplistic to use quantity adjustment. Because it is a short-term project, it is impossible to rebuild factories to increase production in a short period of time, so price adjustment may be more appropriate. On the other hand, in the long term, there is enough time to rebuild the factory, so it can be said that it is suitable for volume adjustment.

On the other hand, in the short term, it can be said that adjusting the quantity or price is not suitable because the price is fixed and there is no time to set up a factory. On the other hand, in the long term, both price and quantity adjustments are possible.

Furthermore, products that sell are subject to both quantity and price adjustments, but products that do not sell are not subject to either quantity or price adjustment.

What we have seen so far makes us wonder whether what is said to be true in economics is really true, and whether what is assumed is a bias on the part of academics. I believe that the correct approach here is to think about it until you are completely convinced. I guess you could call it a critical spirit.

This is Hotaru no Hikari. I think it's best to be flexible when it comes to quantity and price adjustments. What I'm more curious about is that I previously wrote an article about what A=B and C=D are. What if we applied this idea to economics?

For example, the quantity theory of money is interesting. The formula MV=PT is called the quantity theory of money. M: Money supply, V: Money circulation velocity, P: Prices, T: Real GDP. In other words, if the amount of currency M goes around the market V times, T, which is real GDP when the price is P, will be the same amount. By the way, GDP is the total amount of products produced by a country in one year. MV is the currency side and PT is the value side of the produced goods, but we divide this into M=T and V=P. Then, what happens if we multiply the two equations again and rewrite the equation as MP=VT? Honestly, it's a little interesting.

Here, the original formula for the quantity theory of money is, in Japan, M = M3 = 1,467 trillion yen, T = real GDP = 555 trillion yen, and M/T = P/V = 2.63. The new rearranged formula is MP=VT, so M/T=V/P, and V/P=2.63. The original formula P=2.63V, and the rearranged formula P=V/2.63. Does this make sense? I'd like to post another article about A=B and C=D, so stay tuned. See you soon.
