1. How uncertain demand for innovative products for analysis and design? Briefly summarize what methods and strategies
Demand for the product analysis are starting throughout the product life cycle, it relates to product quality, delivery dates, costs and so on. For the uncertainty of demand, it may be composed of two reasons:
First, the method of product development personnel demand or obtain formal description is not enough demand for good cause. In view of this situation, we can regulate to regulate demand by various forms of formal methods, non-formal methods and so on engineered the acquisition and analysis. The uncertainty of the product to minimize. Second, there is uncertainty for innovative products,
It does not "lesson", the market has no relevant reference products, its demand uncertainty is high and demand is not due to acquisition of non-standard way, due to unscientific.
In view of this situation. We can:
1, the use of proof of concept prototype, using axure rp such as prototyping to prototyping, to make the first prototype user interface to the user to confirm and obtain feedback from customers to improve, successive iterations, gradually closer to an ideal version. Rapid development using iterative, first designed and implemented a clear idea of the part. Here, for example, my undergraduate graduation design is derived from the actual demand - designed and implemented a software Arterial blood gas evaluation. Arterial blood gas assessment metrics related to more than a dozen, such as arterial oxygen partial pressure of arterial carbon dioxide partial pressure, and the residual alkali concentration of various ions and the like. The result of the evaluation is divided into ion level assessment, evaluation hypoxia, etc., and these aspects can be assessed at the same time requirements, may be assessed separately. This poses the problem of how to design the interface, and almost no reference to the existing software. How to design a reasonable interface has become a key challenge. For this, our research team and Party --xx doctors several times to discuss the next line of video conferencing and designed several versions of the interface, feedback and after several modifications, the final design and implement an edition interactive experience better software. Here, we use is the proof of concept prototype, the prototype allows users to design our feedback and multiple iterations.

2、在需求分析的流程中,文档化与顾客有关的过程。在软件能力成熟度模型CMM中指出“需求管理的目的是在顾客和软件项目之间建立对将由该软件项目处理的顾客需求的共同理解,与顾客的约定是策划和管理软件项目的基础”。通过与顾客的交流来获取需求,并进行有效的组织和记录;使顾客和项目团队在系统变更需求上达成一致。这样,对与顾客关系的控制依靠遵循有效的变更控制过程,并将其用文档化的程序加以规定,用过程的方法将需求过程加以管理,把需求的不确定因素纳入过程管理之中,加强对需求变更的控制。
3、技术上,尽可能地提高架构的耦合性,梳理出容易变动的部分和不容易变动的部分,用好架构,模式和各种效率工具。
2.以“未来的图书是什么样的?”为例给出您的分析和设计
