This paper empirically examines the implementation pattern of different types of lean management (LM) techniques on the shop-floor. Based on the socio-technical systems framework, LM techniques are classified as social improvement tools and technical process standardization and stability practices. This categorization facilitates investigating their implementation relationship in a complex production system.,Based on the survey data from managers of the three major US auto-manufacturers and their suppliers (n = 137), measurement scales are developed using confirmatory factor analysis for the LM process improvement, stability, and standardization constructs. Hypotheses are tested by applying the Sobel test technique for mediating regression.,Statistical results confirm the mediation role of LM improvement tools between standardization and stability goal practices, indicating that technical process-oriented practices are not directly related and that their association is impacted by the corresponding implementation of social tools on the shop-floor.,The results indicate that LM practices should not be randomly implemented on the shop-floor but rather adopted and executed based on a systematic pattern. In LM systems, the implementation of process stability, standardization, and improvement practices on the shop-floor are more tightly integrated than traditionally assumed.,This study establishes a new categorization of specific LM tools based on social and technical characteristics. The conclusions highlight the importance of adopting a social emphasize of continuous improvement to establish a technical focus of process standardization and stability for LM implementation success.

改进工具对标准化和稳定性目标实践的影响

本文实证检验了不同类型的精益管理 (LM) 技术在车间的实施模式。基于社会技术系统框架，LM技术被归类为社会改进工具和技术过程标准化和稳定性实践。这种分类有助于调查它们在复杂生产系统中的实施关系。,基于美国三大汽车制造商及其供应商（n = 137）的经理的调查数据，使用验证性因素分析为 LM 过程开发了测量量表改进、稳定性和标准化结构。假设通过应用 Sobel 测试技术进行中介回归测试。统计结果证实了 LM 改进工具在标准化和稳定性目标实践之间的中介作用，表明面向技术过程的实践没有直接关联，它们的关联受到车间社交工具的相应实施的影响。,结果表明 LM 实践不应在车间随机实施，而应基于系统模式采用和执行。在 LM 系统中，车间流程稳定性、标准化和改进实践的实施比传统假设的更加紧密。本研究根据社会和技术特征建立了特定 LM 工具的新分类。
