This paper demonstrates the coordinating roles played by decision-making concepts such as Technology Readiness Level (TRL) in industrial engineering practice, where technology development is increasingly complex, involving diverse stakeholders, engineering tools and sociotechnical objects. Such distributed practices demand coordinated efforts across specialized units with diverging interests and perspectives on how development is being defined and accounted for. Nonetheless, coordinating roles of decision-making concepts in industry have largely escaped the recent attention of scholars within engineering studies and Science and Technology Studies. This paper offers an auto-ethnographic study of how the TRL figure of merit was deployed in an industrial organization. We ask how TRL is made to perform as an effective coordinating device. Following the TRL device across project meetings, we consider the three moments of a calculative device as defined by Michel Callon and Fabian Muniesa, to illuminate how TRL serves to circumscribe, configure and coordinate encounters and activity in a technology development project, as managed by the corresponding author. Contrary to linear and mechanistic understandings within management thinking, we show TRL is more than a figure of merit for measuring progress. In the hands of skilled practitioners, TRL also performs as a centralized calculating device to orchestrate distributed activities.

本文演示了决策概念（例如技术准备水平（TRL））在工业工程实践中所发挥的协调作用，在该领域中，技术开发日趋复杂，涉及不同的利益相关者，工程工具和社会技术对象。这种分散的做法要求各专门部门之间进行协调一致的努力，对发展的定义和考虑方法有不同的兴趣和观点。尽管如此，决策概念在行业中的协调作用在很大程度上逃避了工程研究和科学与技术研究领域学者们最近的关注。本文提供了关于民族志研究如何在产业组织中进行部署的自动人种志研究。我们问如何使TRL发挥有效的协调作用。在整个项目会议上使用TRL设备之后，我们将考虑由Michel Callon和Fabian Muniesa定义的计算设备的三个时刻，以阐明TRL如何在技术开发项目中由服务商管理，限制，配置和协调遇到的情况和活动​​。通讯作者。与管理思维中的线性和机械理解相反，我们证明TRL不仅仅是衡量进度的一项绩效指标。在熟练从业者的手中，TRL还可以充当集中式计算设备来协调分布式活动。由相应作者管理和配置技术开发项目中的相遇和活动。与管理思维中的线性和机械理解相反，我们证明TRL不仅仅是衡量进度的一项绩效指标。在熟练从业者的手中，TRL还可以充当集中式计算设备来协调分布式活动。由相应作者管理和配置技术开发项目中的相遇和活动。与管理思维中的线性和机械理解相反，我们证明TRL不仅仅是衡量进度的一项绩效指标。在熟练从业者的手中，TRL还可以充当集中式计算设备来协调分布式活动。
