其次，考虑设计和评估阶段。早期策略和用户分析的资料只有经过系统分析和细化表达，才能有效使用。对象建模是其中一种方法，即根据以前确定的对象对策略和用户分析的结果进行分类，并以图形的形式生动地描述其属性，行为和关系。抽象对象模型可以逐渐转化为不同的具体程度的用户界面视图，即低保真模型和高保真模型。在建立设计模型之后，需要一些手段和方法来验证所表示的模型是否与理想的用户模型相匹配。用户可用性测试和专家评估是两种这样的方法。用户测试方法是向目标用户展示设计模型，并通过用户的模拟使用或讨论等方式获取用户的反馈数据。专家评估方法是邀请专家在人机界面设计和系统功能上进行检查根据他们的经验设计模型，然后指出可用性问题。最后阶段是实施和评估以及任务分析。这个阶段是经过多次迭代设计后的最终高保真模型，是基于企业自身的设计风格和规范进行界面视觉设计。界面设计完成后，需要对项目进行全面的技术测试和用户测试，以保证产品进入市场前的最大完美程度。产品投放市场后，设计师通常需要收集各种用户反馈。这样的信息收集和处理不仅可以帮助当前产品的销售和市场运作，而且可以帮助产品的改进，优化和未来更新。因此，在这个阶段，用户测试应该在不同阶段进行数次，或者采用其他方式来跟踪用户的使用情况和满意度。

Secondly, the design and assessment stage is considered. The materials for early-stage strategy and user analysis can be effectively used only after they are analysed in a systematic way and expressed in a refined way. Object modelling, which is one of the methods, means classifying the results of strategy and user analysis according to the object determined before and vividly describing its attribute, behaviour and relation in the form of graph. The abstract object model can be gradually transformed into user interface views in different specific extents, i.e. low fidelity model and high fidelity model. After the design model is built, some means and methods are needed to verify whether the represented model matches with the ideal user model. The user availability test and expert assessment are two of such methods. The user test method is to show the design model to the target users and obtain the users’ feedback data through users’ simulated use or discussion etc. The expert assessment method is to invite experts in human-computer interface design and system function to examine the design model according to their experience and then point out the availability issues. The final stage is implementation and assessment and task analysis. This stage, which is the final high fidelity model after several times of iterative designs, is to conduct the interface visual design based on the enterprise’s own design style and specification. After interface design, a comprehensive technical test and user test on the project are required to guarantee the maximal perfectness of product before it comes into the market. After the product is put into the market, the designer usually needs to collect all sorts of user feedbacks. Such information collection and processing not only can help the sales and market operation of current product but also can help the improvement, optimization and future updating of product. Therefore, in this stage, user tests should be carried out for several times in different stages or other ways should be used to track the users’ use condition and satisfaction degree.
