[Technical Discussion] relationship between business modeling and user business

 

This conversation discusses the relationship between business modeling and user business and the reasons why the methods in my book are more practical. Finally, I talked about my training and the helplessness of Chinese enterprises.

Hello, teacher.

BEIJING-firespider male 11:43:42

I read a lot of books, as if all the "Business modeling" stages are aimed at "information needs already exist. The "Business modeling" stage reflects the "System" concept.

BEIJING-firespider male 11:44:49

Therefore, there is a "business case" that I cannot understand before ". In this way, the word "Business Case" is related to "system.

Qingrun 11:45:03

Well.

BEIJING-firespider male 11:46:34

Well, it seems understandable. I have never understood it because I put "Business Use Cases" in the perspective of "purely describing Customer business. But now, this is not the case. In the demand phase, you have already entered the requirement.

Qingrun 11:48:48

Business modeling is a modeling of user services.

This process may have traces of past historical systems, or it may be a brand-new system.

BEIJING-firespider male 11:50:50

However, as I said in which group I am talking about, there is a lack of links to "describe the customer's business", and none of the books I bought have a stage of description.

Qingrun 11:52:05

In my book, the description of Business Use Cases will use the status activity diagram or swimming path diagram. These two diagrams are used to draw the user's actual manual business operations or current business operation methods.

Then, we can separate the three metadata use cases that can be implemented by the system.

These three meta-use cases are combined to form actual use cases.

Qingrun 11:53:15

This description is mentioned in my book, but it is not very careful, because it will be a big topic, in addition, the meta-Use Case concept I proposed was not recognized by the industry.

BEIJING-firespider male 11:53:26

Well, you do need a stateful activity diagram or a swimming pool diagram in the demand Section. This diagram seems to have nothing to do with the system, and it feels like it is describing the customer's current business.

There are other books, but they are mixed with case modeling and cannot be seen in an independent stage.

Qingrun 11:54:28

This is what I think is not clearly described in RUP. I use it to describe the details of business use cases. I think this can be described more clearly.

Qingrun 11:55:32

In addition, for use cases, that is, functional and non-functional use cases that need to be implemented in the project after the combination of use cases (that is, the system use cases you mentioned ), I also used the status activity diagram to replace the use case description to achieve complete modeling development, completely out of the document.

BEIJING-firespider male 11:55:40

Well, you have to use it flexibly according to your actual situation.

Qingrun 11:56:53

I can only give you a relatively suitable and comprehensive framework, which requires specific consideration for specific projects.

BEIJING-firespider male 11:57:08

Well, yes.

I especially want to have a new project, which is a little smaller. It is better that the customer does not have any system. I will do it from the beginning.

BEIJING-firespider male 11:58:22

Otherwise, there are still many problems that cannot be understood.

Qingrun 11:58:36

In my previous training, I proposed a project on the site. I spoke and did it. At the end of the training, I could see some code export results.

BEIJING-firespider male 11:58:53

I have never used this idea for many projects that are suitable for analysis in the past, but it is a pity.

Qingrun 11:59:03

Haha.

BEIJING-firespider male 11:59:36

Well, I hope you can give us some training. However, this company has no hope, and even a little training money cannot be spent.

A lot of enterprises cannot do it. It is also true that there is a problem with the upper-level thinking. "The money to be spent should not be spent ".

I don't know what these bosses think.

BEIJING-firespider male 12:01:27

 

Over the years, I have been working in small companies, and the development process is messy, and I have not learned any non-standard things. I rely entirely on my summary and experience to make full use of them.

Qingrun 12:02:38

No way

Chinese bosses are worried that their training personnel are running away. Because of training, you have to pay a high salary and leave without giving it.

I also want to get ready-made and think it is the fastest, cost-effective, and time-consuming.

BEIJING-firespider male 12:02:46

Haha

It is actually the lowest cost for new companies to recruit people.

Qingrun 12:03:37

Therefore, they do not want to train or consult with enterprises.

In addition, the domestic training is mixed, and no one knows why it is so bad.

I don't know how to operate the market because of my credibility.

BEIJING-firespider male 12:04:42

 

Teacher, you still need to think about the operation. In the Chinese environment, making money is the first motivation to cultivate artificial tools to make money.

 

Haha

The concept is quite helpless.

BEIJING-firespider male 12:05:48

 

Lunch break. You can also have lunch. Come back and chat.

Qingrun 12:06:15

Haha, I am a technical or technical manager. I want to perform operations. Although I know something about it, I don't want to share my experience with it, but I am not interested in it.

Even some training I can do, because I feel that there is no technical content, I will refuse.

You can check the training text to see why I used my fully instantiated Training Method to give lectures.
