As the "Solutions Design Book", the "Solutions Design Book", as a high-profile student of the Peking University Computer, Li Gang has done a part-time job between several system integration and software companies, and participated in the development of software projects; Execute the system integration, deeply appreciative. Graduated from the university, Li Gang was enroved by the Gao Zhizhi.
Not long ago, Bounces prepared to undertake projects in Beijing analytical instrumentation plant management information systems. The high total task made the "Program Design Book" handed over Li Gang. Li Gang is full of "program design books" to be completed with its own understanding of hardware and software, and collect information on equipment management systems. However, Li Gang quickly discovered that according to his design, only the cost of hardware and wiring products is far exceeding the budget, and if the advanced management system is introduced, the budget will be higher. Don't have, Li Gang has to ask for experienced Zhao. Zhao Shen pointed out: Li Gang's plan is too ideal, not taken into account the reality of customers; the existing conditions in the northern branch factory should put the program's focus on the basic construction of the hardware platform, software development can only find The most urgent feature of the customer is done first, and the other content can be put in the future project, "I have a fat man" is impossible; in addition, the price of some products is also difficult to be recognized by the user.
Zhao Gong suggested that Li Gang's meetings with the sales department, system integration department and software department, and fully discusses the design plan. Finally, Zhao Shen also made opinions on the content structure of the Program Design Book, such as: Analysis of the needs of customers, to make the product's technical information to annex, and so on.
Li Gang learned that it seems that there is so many "program design book", it seems that it is different from the graduation papers. It is impossible to make "program design book" in the same way. of.
After completing customer demand research and demand analysis, the program service provider should start the production of the Program Design Book (in the project bidding project, also called the bidding). The Program Design Book will fully express the understanding and analysis of designers to customer needs, as well as solutions for customer needs. Usually a "solution design book" is done by the pre-sales engineer, system integration engineer, software engineer, etc. "Scenary Design Book" includes a summary, demand analysis, network architecture technology, software module, project management, budget, attachment, etc. Let's introduce one by one.
Overview, demand analysis is essential
Overview is essential as a "solution design book". "Overview" is usually explaining the development trend of the customer industry, foreign advanced management model, and the purpose, significance of this program. Customer technical person in charge is mostly in this content, they will pass, directly to look at the network architecture and software modules. However, this part must not save, because customer company leaders tend to pay attention to this information, good overview, can even increase the company's decision makers feel good and trust in service providers.
Demand analysis in the Program Design Book, is to make customers understand that the plan designer has fully understood the customer's problems and needs, and provides the lowest risk and the largest solution. Demand analysis generally includes system technical requirements, system design requirements, system functional requirements. In general, considering the growth of customer service, there must be system or function expansion needs.
Description of demand analysis must use the designer's language, avoid the text representations that appear in the Recommendation Recommendation. Moreover, the analysis must respond to all the provisions proposed by the customer, otherwise it may cause the project bidding to fail. If some needs cannot meet, the designer must explain the reasons and propose an alternative.
System design (network architecture), application module is the core
The development of system design and application modules is the core two parts of the IT project, so the expression of their representation is also the core content in the Programming Book.
The system design is an overall description of IT hardware platform design ideas. Generally emphasizes your design principles, such as high reliability, high performance, openness, compatibility, and more. At the same time, it is necessary to use the expression method familiar to the customer, from the professional perspective of IT, using each diagram such as topological maps, etc., to explain important design ideas, so that customers can more intuitively understand the results of the program. Please keep in mind that before you haven't seen the results, the customer's mood is like spending a few pieces of paper. At this time, you will pay special attention to the presence of expected results. If you can use the customer's easy-to-understand chart how to design your design and innovation It is easy to agree. At the same time, the outstanding features of the network architecture should be explicitly explicitly expressly explicitly explicitly explicitly explicitly understand the characteristics of the system. The development of application modules is the largest technical difficulty in IT projects, and it is also most prone to changes, and the risk is generated. Therefore, in the Program Design Book, the software, technical standards / agreement, technical parameters, manageability, technical characteristics, software performance of the application module must make accurate definitions, but also to technical difficulties and The budget makes a full note, allowing customers to prepare for their adequate ideas, which can greatly reduce the difficulty of project change management and risk management. Different application modules, actually different business systems, so when designing application modules, considering the characteristics of the business and the details of a single business operation specification, there is an accurate description of the large number of forms of forms and data logic. At the same time, the process specification between the business is technically seamless link, which requires a sufficient explanation. The application module chart basically includes module topology maps, operational flow charts, system structures, and business flow charts.
Project management, budget, attachment:
The project implementation process is also a process management process. Describe project management, which is conducive to customer understanding of the project, and confident that the program service provider can reach a goal on time and receive expected results. Here to remind the program service provider Note: Designers must pay attention to the introduction to relevant experience. For example, in the previous project, how does the program service provider solve similar problems with customers, and how the results, etc. These experiences are the customer's most important. This facilitates customer understanding of program service providers, and enhances customer trust in programs.
Project budget is one of the most concerned issues of customer policymakers. Therefore, when making budgets, it is necessary to write the standards and expenditures of each budget, which is extremely advantageous for later bidding. In addition, for projects with long cycles, pay special attention to prices and unexpected expenses when doing budgets. The best solution is to set up a specialized preparation fund.
In the "Scenary Design Book" accessory of the IT project, in addition to the common charts, reference sources, abbreviation words, key vocabulary, etc., it is necessary to put relevant technical information involved in the products involved in the program, which is convenient for customers to understand the product. The performance indicators can also make the customer understand why the designer uses these products.
"Kung Fu" outside plan design
It is recommended that channel merchants will recruit a good chart production expert, and how many forms of forms should be formed in the company to form a knowledge of knowledge, so that technology, sales and pre-sales can do a good chart. In addition, different charts, corresponding to different content, such as topological graph express network structure, flow chart performance workflow, Gantt chart performance progress management, there are many charts, pay attention to the normative use.
The content of project management in the program:
★ Change management
☆ Risk management
★ Delivery management
☆ Process Management
★ Human Resource Management
☆ Communication management
