Eliciting scalability requirements during agile software development is complicated and poorly described in previous research. This article presents a lightweight artifact for eliciting scalability requirements during agile software development: the ScrumScale model. The ScrumScale model is a simple spreadsheet. The scalability concepts underlying the ScrumScale model are clarified in this design science research, which also utilizes coordination theory. This paper describes the open banking case study, where a legacy banking system becomes open. This challenges the scalability of this legacy system. The first step in understanding this challenge is to elicit the new scalability requirements. In the open banking case study, key stakeholders from TietoEVRY spent 55 hours eliciting TietoEVRY's open banking project's scalability requirements. According to TietoEVRY, the ScrumScale model provided a systematic way of producing scalability requirements. For TietoEVRY, the scalability concepts behind the ScrumScale model also offered significant advantages in dialogues with other stakeholders.

敏捷激发开放系统的可扩展性要求:案例研究

在敏捷软件开发过程中引发可扩展性需求是复杂的,并且在之前的研究中描述得很差。本文介绍了一个用于在敏捷软件开发过程中引发可伸缩性需求的轻量级工件:ScrumScale 模型。ScrumScale 模型是一个简单的电子表格。本设计科学研究阐明了 ScrumScale 模型背后的可扩展性概念,该研究还利用了协调理论。本文描述了开放银行案例研究,其中遗留银行系统变得开放。这挑战了这个遗留系统的可扩展性。理解这一挑战的第一步是引出新的可扩展性要求。在开放银行案例研究中,TietoEVRY 的主要利益相关者花费了 55 个小时来了解 TietoEVRY 的开放银行项目的可扩展性要求。根据 TietoEVRY 的说法,ScrumScale 模型提供了一种产生可扩展性需求的系统方法。对于 TietoEVRY,ScrumScale 模型背后的可扩展性概念在与其他利益相关者的对话中也提供了显着的优势。
