Complex, Simple, Management

I sometimes lose track of what management is, so I make time to think about this and that.

Today we decided to re-focus on the constraint of "type and amount of work".

First, let's set some simple conditions.

Q1: If one person were to do one type of work in one day or less, would you be able to do it or not?

Yeah, once I get used to it, I think I can do it.

continued

Q2: What five different jobs would one person do in one day or less?

"I'd have to switch heads, and I don't know if I can do that, although I kind of doubt it."

And so on and so on, increasing the number of conditions.

Q3: If five different jobs were to be done within one day by five people with the same experience, what would they be?

Q4: If 5 different jobs were to be done in less than a day by 10 people with different experience?

Q5: If 5 different jobs were to be done in less than 10 days by 10 people with different experience, switching between them, what would you do?

Q6: Assuming that there is an order to the five types of work, and that the next two types of work must not be started until all three types are completed first, and that only three people can do the first three types, and that all ten people can do the remaining seven types, what if the work is done in ten days, with replacement?

It is very complicated.

I don't want to complicate things like this, but, alas, the reality of the job is that it gets in the way before you know it.

But even so, we can't afford to be overzealous, so we're going to have to gather our wits a little more.

Q7: Why does Q6 seem complicated while Q1 is easy?

There are more decisions to be made than at any other time, and if you make a mistake, you don't get a chance to fix it.

Assuming that the answer to this question is "yes," then let's consider the countermeasure.

"If you loosen the restrictions on time as much as possible and reduce the number of branches," he said.

The first is the "I" in the "I" column.

Okay, then I'll simplify Q6.

Q6': 3 people will do 3 different jobs within 3 days. The remaining 7 people watch and learn at the same time. If the pace of the work is too slow to be completed within 3 days, 7 other people will support the work on the 2nd and 3rd days, and from the 4th day, the 7 people who supported the work will do the main work, while the first 3 people wait as support?

I am not sure if this is a good answer. To begin with.

Q8: Are the results achieved in a job as complex as Q6 worth it?

Q9: Where is the quality of the finished product in Q6 guaranteed?

Q10: Isn't there really a way to do it with 3 people instead of 10?

It is necessary to ask the question.

Somehow, I wonder if it is management to think about things like this.

In other words, to take the assumptions that build up over time and work them into a complex and risky group of tasks and project them as simple themes as possible.

Well, plausibly, the reason I have developed the logic at such length is because I felt that the premises in the following puzzle problem were too long and could not be made a little shorter.

Question 9: How many children?

You can hear the kids playing in the yard."

Jones, a graduate student in mathematics, said.

Are they all your children?"

No way!"

Professor Smith raised his voice. The professor is a great authority on integer theory.

My children play with the children of three neighborhoods. It is true that we have the most children in the neighborhood. Mr. Brown's place has the next most, followed by Mr. Green's, and Mr. Black's has the fewest.

How many children do you have in total?" Jones asked.

The professor began his explanation, "Well, let me put it this way.

The number of children is less than 18. And if you multiply the number of children in each of the four families by the number of children in each of the four families, you get exactly our house number. You see, when we arrived home, you saw it too."

Jones took a notepad and pencil out of his pocket and began to do some calculations. After a while, Jones looked up.

I still need more information. Do you have more than one child at Mr. Black's place?"

When the professor answered yes or no to that, Jones immediately, with a smile on his face, correctly guessed the number of children in each of the four families.

In other words, for Jones, who knew the house numbers and knew whether the Black family had more than one child, the answer to the question was obvious, but surprisingly, in fact, without knowing them, the number of each could be uniquely determined based solely on the information given so far. Now, how many of each?
