Abstract

Abstract : Purpose: The purpose of this paper is to explore how Lean and Six Sigma's distinctive practices relate to potential absorptive capacity (PACAP) and realized absorptive capacity (RACAP). The paper seeks to understand which of the practices in Lean Six Sigma are needed to manage absorptive capacity systematically. Design/methodology/approach: Partial least square based structural equation modeling (PLS-SEM) was used to test the theoretical model drawing on a sample of 125 manufacturing organizations in Malaysia. In addition to examining direct effects, the study also examines indirect effects using bootstrapping method to identify possible mediation effects proposed in the model. Findings: The results explain that Lean's social practices (LSP), Six Sigma's roles structure (RS) and structured improvement procedure (SIP) positively influence potential absorptive capacity (PACAP). Meanwhile LSP, RS and focus on metrics (FOM) positively influence realized absorptive capacity (RACAP). SIP was found to influence RACAP through PACAP. The analysis reveals the combination of Lean Six Sigma practices that are required in managing PACAP and RACAP differentially. Research limitations/implications: The study is only confined to manufacturing industries in Peninsular Malaysia. Data collected were cross-sectional in nature. The application of Lean Six Sigma and how it influences absorptive capacity may get sturdier across time, and this may change the effect toward sustainability of firm's competitive advantage. A longitudinal study may be useful in that context. The study also makes specific recommendations for future research. Practical implications: The results of this study can be used by Lean Six Sigma practitioners to prioritize the implementation of Lean Six Sigma practices to develop absorptive capacity of the organization through PACAP and RACAP, which needs to be managed differentially as they exert differential outcomes. This would enable organizations to tactfully navigate and balance between PACAP and RACAP in accordance to business strategies and market conditions. Originality/value: Absorptive capacity in Lean and Six Sigma context has largely been studied as a unidimensional construct or used as a grounding theoretical support. Therefore, understanding the multidimensionality through PACAP and RACAP provide insights on how to enhance and maneuver absorptive capacity through Lean Six Sigma systematically. The findings may pave the way for future research in enhancing the current knowledge threshold in Lean Six Sigma.
