Purpose

The purpose of this study is to explore the mediation effect of volatile economic conditions on performance benefits of successful kean manufacturing implementation (LMI). The mediating factor of economic volatility (EV) is constructed based on four macroeconomic dimensions – supplier uncertainty, market demand fluctuations, governmental policy changes and peer competition.

Design/methodology/approach

An attempt is made to build an exhaustive list of the internal operational manifests grouped into one human and three technical input factors. Similarly the benefits accrued are collated under two performance measures – customer satisfaction (CS) and organizational goal satisfaction (OGS). Based on data from the Indian manufacturing sector, structural equation modelling (SEM) and ordinary least square (OLS) analyses are carried out to validate the proposed model.

Findings

Results of the structural model validate the first six hypotheses posited in the model. Results of OLS further reveal the mediation effect of EV having negative impact on LMI–CS and LMI–OGS nexus.

Practical implications

This research offers a fair understanding of the internal operational lean factors and the effect of volatile macroeconomic conditions on lean benefits. The structural model will aid the academicians and lean implementers comprehend the dimensional structure underlying the lean practices and beliefs. This work further helps to understand the moderation effect of environmental complexity on the output measures of LMI in the Indian manufacturing sector.

Originality/value

This work is one of the very first empirical analyses of lean performance under contingent economic conditions. The paper presents a valuable recommendation to practitioners for considering the dynamism of external economic environment instead of simply adopting standalone internal lean parameters, if satisfactory levels of performance in terms of CS and OGS are to be achieved.

精益生产的实施和绩效：经济波动在新兴经济体中的作用

目的

这项研究的目的是探讨波动的经济条件对成功的基恩制造实施（LMI）的绩效收益的中介作用。经济波动（EV）的中介因素是基于四个宏观经济维度构建的–供应商不确定性，市场需求波动，政府政策变化和同业竞争。

设计/方法/方法

试图建立一个完整的内部操作清单清单，该清单分为一个人和三个技术输入因素。类似地，将产生的收益归结为两个绩效指标–客户满意度（CS）和组织目标满意度（OGS）。基于印度制造业的数据，进行了结构方程模型（SEM）和普通最小二乘法（OLS）分析，以验证所提出的模型。

发现

结构模型的结果验证了模型中提出的前六个假设。OLS的结果进一步揭示了EV对LMI–CS和LMI–OGS关系的负面影响。

实际影响

这项研究提供了对内部运营精益因素以及不稳定的宏观经济状况对精益收益的影响的公正理解。结构模型将帮助院士和精益实施者理解精益实践和信念基础的维度结构。这项工作还有助于了解环境复杂性对印度制造业LMI产出指标的适度影响。

创意/价值

这项工作是在偶然的经济条件下对精益表现进行的最早的实证分析之一。如果要实现CS和OGS方面的令人满意的性能水平，则本文为从业人员提供了宝贵的建议，以考虑外部经济环境的动态，而不是简单地采用独立的内部精益参数。
