[Repost] How to become a good system analyst
How to become a good system analyst Truely design definition: the process of design is the process of processing the transaction abstract into a computer model. 1. First, you must understand that the design is far more important than programming. 2. Implemented the training of our own thinking and considering problems from global. Establish an attitude attitude of cool thinking. 3. When designing (especially when designing the database design) Don't be completely restrained, the design is better than the poem, knowing that the rhythm is right, but it is completely chained by the rhyme, it will not make a good poem. 4. Do more design, often summarizing your shortcomings and success, ask others. 5. Specialize in finding the vulnerabilities and deficiencies designed by others, but also an important means of improving their design level. (Remember: This kind of method should not pass through, you know it, 嘻嘻 - :) 6. Experience is important, but if the concept is aging, it is not good at summing up, the so-called experience is a shackle that binds yourself. 7. Learn a good mathematics, especially theoretical mathematics such as mathematical analysis, operation planning, mathematical models. It is also beneficial to play a strategic business game. Recommend "Imperial Times" and "Simulation Capital 3000" and "Master 4". (But do not sink inside) 8. The best design method is determined based on the characteristics of the project and the development platform tool. Modular design method and object-oriented design. The combination of two design methods is used. 9. Decompose complex procedures with modular methods, but should focus on the connection between transactions, and use open vision to design. 10. Measurement of stringency, flexibility, development efficiency, and customer requirements during design. 11. Designfully designed to decide whether to decide whether to design enough flexibility and rigorous in accordance with the progress of the entire project and customer requirements. 12. Complex and unconditional is the worst design, simple and practical is not necessarily the best, but must not be the worst. (Don't say that I am lazy) 13. Training your own good expression ability, expressing clear and clear and simple descriptions express their basic ideas. 14. Establish a unified system analysis model and document template in a project, and at least one person must check and perform globally considers in a project. Let me talk about how to become a good system analyst? BYLSFBOY system analyst basic work: Good system analysts are produced from excellent programmers, solid programming, rich experience is the basis for systematic analysis in the future. There is no thorough analysis of the system itself, it is difficult to understand some of these difficulties. But not equal to a good programmer can become a good system analyst. Reasonable knowledge structure. Language ability, text expression ability, comprehensiveness of technology, etc. are the basic requirements for system analysts. For example, C / S and 3-layer development, if it is familiar with Netscape products, it is necessary to understand, such as Microsoft and other products, and to understand their history, development ideas, technical advantages and disadvantages, to cope with various poor chasing. Summary question. But more importantly, this is the premise you use custom technical requirements. System Analyst Thoughts: Global Concept is the concept that system analysts must have. If the system analyst is designed too much attention to details, it is often trapped in a quagmire on a certain issue. (93 years, my aphrographic guidelines have affected the understanding of software development in the next few years --- In the future, the computational opportunity is getting faster and faster, and write a few lines of code less write code. The most important thing is the whole; At the beginning, it was wrong, some part was better, and it was also useful) The predictive ability system analyst to have a fast task difficulty prediction capability and the ability to quickly determine the development group personnel constitution and task division. (I will return this to my thoughts, not the ability) insects will naturally go out of wings, but their thoughts require long-term infiltration. To do this, you need a lot of thinking and learning. Design is much more important than programming.
The development of the software industry, the emergence of various development tools, the programming is not a problem, and the programmer's work is aware of the existing things that others are piled up. System analysts must clearly understand that most programmers have not learned how to understand a system overall, some don't even understand programming (this is not said that they don't write code). Visual development tools plus five-flowered control, programmers can steal. (This is not exaggerated, I have been managing the management of several years, exposed to a large number of programmers) based on technology, and jump out of the framework. Jump out of the framework based on the problem of user demand. System Analyst Thoughts: System Analyper must have a user-oriented thought. System analysts should have the ability to play themselves into users, to understand what they want to deliver, think what they think, thus understanding the user's ideas and picking out a reasonable part. In this sense, system analysts can get meaningful insights to guide his development group members. The system analyst has a clear understanding of the project outcome, and guarantees that the project does not deviate from the direction. System analysts must have ideas that rooted in technology, higher than technology thinking. Pure programmers often consider the final result. When a new technology appears in the market, they are relatively small for delivery on time, and strongly hope that their plan can be built in new technology. on. Therefore, the system analyst's ideas and actions should be like a user, and it is also possible to stand in the height of technology, becoming a true user, the spokesperson between programmers. System analyst's key to trust. The most important quality of system analysts is to achieve trust, which is the key to the excellent system analyst. Mature is the most important. Mature can provide correct support for the entire project group, understand how technology can solve user needs. System analysts are prepared in various document modes, including future software variables, field naming rules. I recommend the basis for the rules set by PB, and by changing the standards suitable for their utility. Unified document management. Unified analysis software. For example, Rose (UML is too standardized, the domestic software management level is not used, but only as much as possible, your own understanding of the systematic analysis is good) The method is the show, and there is not much to say in the specific method. I got a few books from U $ A, used for the use of object-oriented system development, "object-oriented analysis", "project management" is very good, recommend everyone to see. I have sent a glimpse of "I have a computer in China." I heard that some people (habitual). In fact, BBS was originally vented, and there was a rare article here. Since the "Venus" landed in Shenzhen, everyone is more eye-catching from the macro look at China IT industry. China IT this small tree is really not easy to grow today. Some people put forward the slogan of "opposing Microsoft Hegemony", many people call for the emergence of China's "Silicon Valley". Microsoft's success is not the success of technology, more is the success of business operations. China IT This tree can grow high, depending on the soil he rooted. The current fact is that this soil is really barren! If we don't have a big tree according to our current ideas and law, don't expect to have a fruitful fruit that "micro-soft" and "Silicon Valley". If our software technology is behind the United States ten years, our hardware manufacturing technology is behind the United States for 20 years, and our management is backward in the United States for at least 30 years. The ultimate decision of development is just our death - poor management level. The reason for the formation of poor management level has a deep background and a multi-faceted reason.
Systematic analysis work is to solve a problem, the goal is to transform a demand for computer application into actual physical implementation, which is complex and complex in the actual surface. In the system analysis process, you will pay attention to the following problems. The system analysis design work may be helpful. 1) What is the purpose of the system you have finished? Note that it is not a functional requirement, but the purpose. That is, why do you want to build, why do you want modern construction. 2) What are the participation of the system you have finished, what is the original intention of all aspects? Those people may play an important role in system construction, what kind of attitude would be taken? How much influence do you have? 3) Does your system have a clear evaluation criteria? It is best to consider from all aspects of participation. 4) What is your system design idea? Whether it can be recognized by all aspects. 5) Do you know the personnel involved in the design and development of system? Where is their special length, is it willing to cooperate with you, why? Do you have enough influence on them? 6) Is your system development plan perfect? Does your plan have a clear stage? What should I do at any stage? How to evaluate this situation? 7) Are you familiar with the system development methods and tools used? Is your partner familiar? 8) Do you have a prototype? Computer or physically. Several problems above are involved in systematic analysis and system planning, for all reference. Systematic analysis work is to solve a problem, the goal is to transform a demand for computer application into actual physical implementation, which is complex and complex in the actual surface. In the system analysis process, you will pay attention to the following problems. The system analysis design work may be helpful 1) What is the purpose of the system you have finished? Note that it is not a functional requirement, but the purpose. That is, why should we build, why do you want modern construction. When considering the purpose of the system, I focus on the ultimate goal of the system, because a system is not perfect, there will be some room for the system. 2) What are the participation of the system you have finished, what is the original intention of all aspects? Those people may play an important role in system construction, what kind of attitude would be taken? How much influence do you have? One of the failures in China's IT industry is that people "too young" must have leadership support, otherwise they will end. Don't think that you have much influence on them, even if you have, it is necessary to think that decision makers will affect them. In China, a technician, do you have a few a few? I am very sad about saying this here. Whoever plays an important role in the system and clarifies their attitude, this is critical. 3) Does your system have a clear evaluation criteria? It is best to consider from all aspects of participation. I don't know if this is wrong, before the construction of the system, the programmer for you, there must be at least two different evaluations for your leaders. 4) What is your system design idea? Whether it can be recognized by all aspects. If it is high, the leadership, the best way to use the programs, is recognized, that is, let them recognize their own ideas. (I try to do this, but don't do it, the system analyst has to learn to be a light, tolerate) 5) Do you know the personnel involved in system design and development? Where is their special length, is it willing to cooperate with you, why? Do you have enough influence on them? The software has developed to a certain level, not programming, not mathematics, but management.
