In recent years, organizations have increasingly sourced cloud-based enterprise software (ES). Although comprehensively capturing organizations’ requirements considerably affects the success of an ES sourcing project, little is known about how requirements evolve beyond the implementation. We conduct a longitudinal, exploratory single-case study of the life cycle of cloud-based ES in a medium-sized organization. Over 5 years, we trace the evolution of requirements throughout the ES life cycle, beginning with the initial adoption decision and ending with considerations to retire the ES. We develop a process theory that explains how requirements evolve beyond ES implementation and throughout its life cycle. We isolate nine mechanisms that explain how contextual factors and experiences are intertwined and shape the evolution of requirements. We then develop seven propositions that explain how sourcing cloud-based ES alters the mechanisms that shape the evolution of requirements. Our findings emphasize that the evolution of requirements for cloud-based ES follows similar mechanisms to that of the requirements for on-premises ES but changes how particular mechanisms manifest. Sourcing cloud-based ES changes the influence of business divisions in acquisition and configuration activities, the role of upgrade and customization procedures, and the influence of the ES’ ecosystem.

需求如何随时间演变?调查上下文和经验在企业软件需求演变中的作用的案例研究

近年来,组织越来越多地采购基于云的企业软件 (ES)。尽管全面捕获组织的需求会极大地影响 ES 采购项目的成功,但人们对需求如何超越实现而发展却知之甚少。我们对一家中型组织中基于云的 ES 的生命周期进行了纵向、探索性的单一案例研究。5 年多来,我们跟踪了整个 ES 生命周期中的需求演变,从最初的采用决定开始,到考虑淘汰 ES 结束。我们开发了一个过程理论来解释需求如何超越 ES 实现并贯穿其整个生命周期。我们隔离了九种机制,这些机制解释了上下文因素和经验如何交织在一起并影响需求的演变。然后,我们提出了七个命题,解释了基于云的 ES 采购如何改变塑造需求演变的机制。我们的研究结果强调,基于云的 ES 需求的演变遵循与本地 ES 需求相似的机制,但改变了特定机制的表现方式。采购基于云的 ES 改变了业务部门在收购和配置活动中的影响、升级和定制程序的作用以及 ES 生态系统的影响。我们的研究结果强调,基于云的 ES 需求的演变遵循与本地 ES 需求相似的机制,但改变了特定机制的表现方式。采购基于云的 ES 改变了业务部门在收购和配置活动中的影响、升级和定制程序的作用以及 ES 生态系统的影响。我们的研究结果强调,基于云的 ES 需求的演变遵循与本地 ES 需求相似的机制,但改变了特定机制的表现方式。采购基于云的 ES 改变了业务部门在收购和配置活动中的影响、升级和定制程序的作用以及 ES 生态系统的影响。
