Over the last two decades, agile software development (ASD) has garnered much attention in both research and practice. Several ASD methods and techniques have been developed and studied. In particular, researchers have provided several theoretical perspectives on ASD and contributed rich insights to the ASD practice. Still, despite calls for a more unified theoretical understanding of ASD, a theoretical core of ASD has not been identified. This paper offers a theoretical core of ASD research, clarifying what is essential and what is less essential for IS agility, hoping to spark a scholarly discussion, and provides implications of such a core for understanding method tailoring.

敏捷软件开发研究的问题、挑战和提出的理论核心

在过去的二十年中，敏捷软件开发 (ASD) 在研究和实践中都引起了广泛关注。已经开发和研究了几种 ASD 方法和技术。特别是，研究人员提供了多种关于 ASD 的理论观点，并为 ASD 实践贡献了丰富的见解。尽管如此，尽管呼吁对 ASD 有更统一的理论理解，但尚未确定 ASD 的理论核心。本文提供了 ASD 研究的理论核心，阐明了对 IS 敏捷性来说什么是必不可少的，什么是不太重要的，希望能引发学术讨论，并提供这样一个核心对理解方法裁剪的意义。
