In this article we adopt Barad’s theory of agential realism to explore how power and performativity are simultaneously processual and ontologically entangled. We use the hyphenated term power-performativity to mobilize an exploration of how power is not an ‘outcome’ or ‘effect’ of, but an inseparable flow within, the processes of performativity through which the world is continuously becoming. This moves us beyond the traditional, anthropocentric take on the relationship between power and performativity which emphasizes human agency and linear cause-effect, toward an alternative understanding of organizational phenomena as always enacted through myriad intra-acting more-than-human actants. To empirically mobilize this approach, we explore power-performativity within online healthcare, enacted through Personal Online Healthcare Communities (POHCs). We explore multiple ‘diffraction gratings’ through which particular outcomes of online healthcare come to matter, while others are prevented from mattering. In doing so, we posit the suitability of Barad’s agential realism for further explorations of the dynamics of power and performativity in modes of organizing and organizational life and offer tools for how these may be done.

在本文中，我们采用巴拉德的代理现实主义理论来探讨权力和执行力如何同时在过程和本体论上纠缠在一起。我们使用连词“权力-执行力”来动员探讨权力如何不再是整个世界不断成为的执行力过程的“结果”或“效应”，而是其中不可分割的流动。这使我们超越了传统的，以人类为中心的，强调权力和绩效之间关系的强调人的代理权和线性因果关系的方法，转向了对组织现象的另一种理解，这种现象总是通过无数次内部行动多于人类的行为者来实现的。为了凭经验调动这种方法，我们探索了通过个人在线医疗保健社区（POHC）制定的在线医疗保健中的电源性能。我们探索了多个“衍射光栅”，通过这些衍射光栅，在线医疗保健的特定结果将变得重要，而其他结果将变得无关紧要。这样做，我们认为巴拉德的代理现实主义适用于进一步探索组织和组织生活模式中的权力和绩效动态，并提供了实现这些目标的工具。
