Information systems development (ISD) requires dynamic and flexible ways of working, particularly when developing requirements in collaboration with customers. Although prior research has acknowledged the importance of objects to support ISD practices, there has been a lack of frameworks to help discern the multiple overlapping roles objects play to support requirements development in a variety of ways throughout an ISD project. This paper explores and theorizes this phenomenon by leveraging multiplexity as a theoretical lens to analyze an extensive qualitative data set from a case study at a Swiss multinational banking software provider. Results show how diagrams and prototypes both play the roles of epistemic, activity, boundary, and infrastructure objects as a reflection of how they are used in requirements development. Our analysis articulates how two classical requirements specifications play multiple overlapping roles to support dynamic and flexible ISD practices. Based on these findings, we advance a framework for discerning the multiplex role of objects in practice

信息系统开发 (ISD) 需要动态且灵活的工作方式，特别是在与客户协作开发需求时。尽管先前的研究已经承认对象对于支持 ISD 实践的重要性，但仍然缺乏框架来帮助识别对象在整个 ISD 项目中以各种方式支持需求开发所扮演的多个重叠角色。本文利用多重性作为理论视角，分析瑞士跨国银行软件提供商案例研究中的大量定性数据集，对这一现象进行了探索和理论化。结果显示图表和原型如何扮演认知、活动、边界和基础设施对象的角色，反映它们在需求开发中的使用方式。我们的分析阐明了两个经典的需求规范如何发挥多重重叠的作用来支持动态和灵活的 ISD 实践。基于这些发现，我们提出了一个框架，用于识别实践中对象的多重角色
