Mainly from four views to analyze design, finally transition to demand documents and system design. These four views are:
l Business Vision
l business structure
l Business behavior
l Business process
Because of different aspects of these illustrations, it is not separate views, so it is possible to consider one, and it is possible to consider multiple views at a time.
First, business vision
Business's vision includes business views and the goals he want to achieve, and is described by vision statement and target models. If you don't define some key concepts, we have difficulty expressing the vision statement and goals. Therefore, we can create a conceptual model at the same time to implement this view and help clarify the key concepts in your business.
1. Target model
First, based on the aspects and objectives of the business, how to achieve these goals (and customers), break the big target into a phased target until minimize. To find out the shortcomings of the business, the "target model view" of the service is depicted according to the above analysis.
2, concept model
In order to achieve the target model, a conceptual model is proposed. Some key concepts are defined in this model, which is very important to our business modeling. For example: business plan, product strategy, product set description, etc.
Second, the business process
The business process focuses on how to achieve business vision statements, target models, and conceptual models outlined. We can define process hierarchical supply patterns through process layering. These powerful modes can usually be used together to simplify most of the services.
Third, resources and organizations
Resources and organizations are modeling in business structure. The organizational model shows the structure of human resources, and the resource model shows the structure and behavior of other resources, these resources include products, documents and machines. Those resources in the resource model are primarily those in process models.
1, resource modeling
Based on the above analysis, identify key concepts in the conceptual model, analyze the possible states.
2, organize modeling
Thoroughly understand the structure of an organization, his importance is not only the purpose of reconstruction, but also is also important for the responsibility of the name of each organizational unit. At this point we can use UML activities to describe the interrelation and workflow of the organization.
Fourth, process decomposition
The complex process can be decomposed, which can be better understood. At this point, these decomposed processes can be depicted in the way, how many sub-processes should have much views, and the details of the entire business system should be understood.
V. Support system
It can be understood that it has achieved good business scores, and system support for software and hardware that must be implemented. Thereby, the general model of the entire system architecture is obtained.
Sixth, enter the system demand design
