While pursuing document specifications, domestic software companies ignore the importance of chart charts and Interactive Operation Simulation for the transfer of research content.
The document is just a means of assisting the description of the demand research content. It would be extremely sad to use it as the only carrier of the demand research content. The document mentioned above is a flat document for the time being, which lacks the user interaction experience.
Including the documentation required by the Maturity Model of CMM software. with the complexity of the software system and the improvement of the application level, the document content must be continuously expanded and extended. With the development of multimedia technology and the popularization of Application Software Modeling development. The authenticity and simulation requirements of domestic demand research must be higher and higher.
We have gone through some ways to improve: using the molding software to do the original form of demand research. This is a good way to quickly introduce your management philosophy and system functions to users, so that users' thinking can be converted to "when I use this system in the future, what other defects does he have? Is there a better implementation method?" Instead of "What functions should the system have in the future? How should this function be implemented ?". However, we are also faced with such confusions that the system is built to meet the special needs of users, due to technical defects in development, the requirement investigator cannot quickly construct a business office form that can be interactive and simulated to communicate with the user according to the user's needs, thus losing valuable first-hand information.
Therefore, we can use the business Rapid Modeling Method to complete the computer simulation of the business manual processing mode. This allows the project's demand research content to be intuitively explained through computer simulation operations, so that the demand research content not only stays in the interview and text description stages, of course, supplementary descriptions in the document are essential.
In general, when conducting a demand survey, we will form three main results: Organizational Structure Survey, business process survey, and software and hardware environment survey. Map the results of these three aspects to the computer description of the user's requirement model: organization model, business model, and resource model.
- The organizational model can be subdivided into users, positions, and permissions;
- The business model can be further subdivided into: business status, business role, business permission, and business form (input, query, new modification, and output), business reports, business processes, data models, business resources (components, services (web service, job service), scripts, messages );
- The resource model can be subdivided into: basic class library, extended class library, template center, registration component, and registration service.
The above are the basic functional requirements of the static management framework, and there is still a dynamic runtime framework that supports business flow. The following uses an abstract business process as an example to describe the main functional requirements for business model definition and simulation. The general business in Computer Implementation basically includes the following aspects: entering information, querying information, handling notifications, querying the handling process, handling notifications, return notifications, and handling circulation.
- Case Transfer and case handling notifications are the fundamental elements for organizing and managing business processes and making them collaborate;
- Information collection is essential for business processing;
- Information Query (Summary) is an auxiliary demand for business processing. The Status, permissions, roles, forms, reports, resources, and other elements are organized through business processes to form a business model that can be transferred. Each work node is subject to the role, operation form, operation report, operation resource, and handling time limit (whether it is included in the working time) the business model element of the workflow submission Processing Mechanism describes the content of each worker node.
In addition, the business model can generate business research results, such as Word documents.
