Digital transformation has become a central construct in information systems (IS) research. Current conceptualizations largely attribute transformation to intentionality, focus on transformation within a single organization, or assign technology the role of a disruptive agent of change. Likewise, “digital” tends to be a general category of technology, rather than a specific technology enacted in a time and place. Inspired by Schatzkian practice theory and its site ontology, we suggest a contextual viewpoint on digital transformation and call it “relational digital transformation.” We analyzed the change dynamics in the context of taxi dispatch practice in Finland, studying the changing taxi dispatch platforms over years. We investigated five powerful industry actors: two incumbents, two entrants, and a federation of taxi entrepreneurs. We identified events of change in the material arrangements in sites and explain the changes through the process dynamics in the focal practice. We define relational digital transformation as a process through which practice-arrangement bundles of digital technologies evolve over time. This approach assumes the default nature of an industry is to be found in the changing relations between entities rather than in entities themselves. This provides a theoretical extension to the prevailing views of digital transformation in IS literature. It enables studying digital transformation in retrospect without attributing change agency to any entities or technologies a priori. We also contribute to practice-theoretical IS literature by demonstrating how the applicability of practice theoretical analysis extends beyond microphenomena to larger industry-level changes.

数字化转型已成为信息系统（IS）研究的中心架构。当前的概念化很大程度上将转换归因于意图，将重点放在单个组织内的转换上，或将技术分配给变革的破坏性因素。同样，“数字”往往是技术的一般类别，而不是在某个时间和地点制定的特定技术。受沙特兹实践理论及其站点本体的启发，我们提出了有关数字转换的上下文观点，并将其称为“关系数字转换”。我们分析了芬兰出租车调度实践中的变化动态，研究了多年来不断变化的出租车调度平台。我们调查了五个有影响力的行业参与者：两名在职者，两名进入者以及出租车企业家联合会。我们确定了现场物料布置中发生变化的事件，并通过焦点实践中的过程动态来解释这些变化。我们将关系数字转换定义为一个过程，数字技术的实践安排包将随着时间的推移而发展。这种方法假定在不断变化的关系中可以发现一个行业的默认性质。实体之间，而不是实体本身之间。这为IS文献中的数字转换主流观点提供了理论上的扩展。它使研究在回顾数字化改造没有变化归因于机构的任何实体或技术先验。通过展示实践理论分析的适用性如何从微观现象扩展到更大的行业水平变化，我们还为实践理论IS文献做出了贡献。
