Is lean service promising? A socio-technical perspective

Purpose - The purpose of this paper is to contribute to the ongoing debate about the effectiveness of lean practices in the service sector. Design/methodology/approach - This paper examines the impact of lean service on firm operational and financial performance. Exploratory factor analysis is used to reduce the data and identify the underlying dimensions of lean service, and partial least squares structural equation modelling is used to test the developed model. Findings - The results indicate that the social bundles of lean service had an independent positive impact on firm operational and financial performance. Furthermore, while the technical bundles had an independent positive effect on only the operational performance, they interacted with the social bundles to improve both the operational and financial performance. The findings suggest that service managers must follow a systematic approach when implementing lean service practices without focusing on one side of the system at the expense of the other. Practical implications - The paper highlights the importance of implementing lean service as a socio-technical system (STS) if service firms are to achieve the best possible benefits from their implementation. The motivation factor (social side) and the customer value factor (technical side) are capable of improving all operational performance dimensions and profit margin even if implemented alone. Therefore, service managers with limited resources are encouraged to start lean service implementation with practices within these factors. However, they can also expect improved operational and financial performance from implementing other factors as they positively interact to further improve performance. Originality/value - Viewing lean service as a STS, this paper incorporates a larger set of lean practices than previous studies and demonstrates empirically their capability of improving service firms' operational and financial performance. It contributes significantly to the emerging literature on lean service by empirically testing the mechanism through which lean service affects firm performance.
