The objective of this paper is two-fold. First, it aims at empirically validating bundles of Lean Automation (LA) practices and principles. Second, it verifies their impact on operational performance improvement. For that, we surveyed 110 manufacturers who have been concomitantly implementing Lean Production (LP) and Industry 4.0 (I4.0). The collected responses were examined using multivariate data analysis techniques. We identified three bundles of LA named according to the focus of the corresponding practices (i.e. workplace, value stream and extended value stream), and two bundles of LA principles (sociocultural- and technology-oriented). Our findings indicated that LA practices positively mediate the relationship between LA principles and the company's operational performance, especially when considering practices applied at a workplace or value stream level. As the integration of I4.0 into LP becomes widespread, the LA paradigm tends to be a more relevant topic in the operations management field. Hence, more profound comprehension of LA practices and principles, and their implications on companies' operations may help achieve higher performance, setting the proper managerial expectations.

本文的目的是双重的。首先，它旨在凭经验验证精益自动化（LA）的实践和原则。其次，它验证了它们对运营绩效改善的影响。为此，我们对110家同时实施精益生产（LP）和工业4.0（I4.0）的制造商进行了调查。使用多变量数据分析技术检查收集的响应。我们根据相应实践的重点（即工作场所，价值流和扩展价值流）确定了三类LA命名）和两套LA原则（面向社会文化和技术）。我们的研究结果表明，洛杉矶实践可以积极地调解洛杉矶原则与公司运营绩效之间的关系，尤其是在考虑在工作场所或价值流层面应用的实践时。随着将I4.0集成到LP变得越来越普遍，LA范例在操作管理领域趋向于成为一个更相关的主题。因此，对洛杉矶惯例和原则的更深刻理解及其对公司运营的影响可能有助于实现更高的绩效，设定适当的管理期望。
