Exploration demand (6) - Business VS System
"Programmer" magazine has articles Panjia-seventh article, "Business Modeling VS system modeling." Just recently has done business modeling, and system modeling work, the article on the views of many in this remark.
?
1, "Business Modeling does not mean that a software project development to follow."
Recall that a year ago, a company I will speak, to illustrate thorough analysis of solid research units, the actual business of the latter part of the analysis of the important system requirements and the need to avoid premature to consider software system design needs even when I say "we on the assumption that our research is not to develop software is to clarify the actual business, establishing a business model to optimize business management. " I think the only way we can prevail in their own recklessness, technical staff often premature to system analysis and design to cover up its business Xilihuchu. They are often not clear in the actual act on the business of the future system, and in real systems analysis and design, went to the actual business of act, of course, this analysis and design is built on sand dunes in the building. So when we complain about customer needs always change, we have to reflect on is not their business for many years never change is not our business is not really understand, of course not good catch to the customer's true needs , not to mention the needs of value to the customer recommendations.

2, "Business Modeling to describe the 'battlefield' the true situation, and help you find software from the starting point"
Recently a subsystem of the project is the transformation of business models to first establish a system to the preparation of cases before entering demand analysis and design process. Systems used in the preparation of cases, more complex encountered a chaotic situation, the system can not be used with current events of the time, I will always carefully read business model, in particular the business use case in the real basis of the actual business boost What carding system needs to be done, how to do system is more suitable for a customer's current business model, how can we allow customers are using our system to bring them a convenient, rather than bring the benefits of trouble (of course, there must be a degree , as customers limited to the money). Prepared with such cases in the auxiliary system to system prototype, we should be able to close more customers. And the design of the system before obviously little knowledge of the actual business, because business in the most complicated situation is precisely the original system design can not be unreasonable or wrong with the design.

3, "the business model results are automatically mapped to the needs of software?"
This is obviously impossible. The core business model - business use case, the description is the actual business scene. Demand model of the core - System of cases, the description of the software users in the future and the future delivery of the interactive system software scene. Perhaps in the case of an operational system using multiple systems will be used in cases to cover the value of this work. Perhaps a system can be used to achieve a number of cases can be achieved with business objectives. In addition, the system object model may not be the object of business entity is an entity in the model, they can correspond. That the best evidence of the above, if the results of business model can be automatically mapped to the software needs of today that I will not read a business model prepared by the system used to thinking of a headache sometimes. Although they are mainly used by patients with technology, which, after all, is different from this.
