目的 在体验经济时代背景下，APP快速迭代导致软件新颖性与可用性之间的对立冲突愈加频繁，探索如何构建两者的和谐关系成为一项亟待解决的设计研究问题。方法 从界定新颖性和可用性的概念入手，通过系统梳理两者的不同关系，结合文献研究法、案例分析法进行归纳和演绎。结果 得出新颖性与可用性的3种关系，提出新颖性与可用性和谐关系的构建方法。结论 新颖性与可用性之间存在冲突、不相干和一致3种关系。在此基础上，初步提出促成新颖性与可用性和谐关系的“4+3+1”辅助方法体系，同时构建出软件新颖性设计的一致性趋向框架，为企业软件迭代开发提供参考和帮助。

Under the background of the experience economy, the rapid iteration of apps leads to more conflicts between software novelty and usability. It is an urgent problem to explore how to strike a proper balance between them. This paper starts by defining the concepts of novelty and usability, systematically sorts out the different relationships between them, and summarizes and deduces the solutions with the methods of literature research and case analysis. In conclusion, three relationships between novelty and usability are obtained, and the construction method of the harmonious relationship between novelty and usability is proposed. There are three relationships between novelty and usability, namely conflict, incoherence and consistency. On this basis, the “4+3+1” auxiliary method system is proposed to bolster the harmonious relationship between novelty and usability, and the consistent trend framework of software novelty design is correspondingly set up, which provides reference and help for the enterprise’s software iteration and development.
