Critical success factors for lean six sigma in quality 4.0

Purpose Critical success factors (CSF) for lean six sigma (LSS) using quality 4.0 are not researched so far. This study aims to bridge this gap. It also validates CSF already identified for LSS under conventional technologies. Design methodology approach Empirical research using the questionnaire method is conducted. Construct of the questionnaire is checked using Cronbach's alpha and responses received are analysed using t-test and exploratory factor analysis. Findings In total, 20 factors are evaluated for LSS success. It includes 7 factors related to quality 4.0 technologies and 13 related to the conventional set-up. All 7 quality 4.0 related factors were found critical; whereas, under traditional set-up, 11 factors out of 13 were found critical. Practical implications The study will help enterprises in the fast and effective adoption of quality 4.0 and seamless integration with LSS. The post-Covid-19 business scenario is expected to be information technology focussed. The findings of this study will be useful in these circumstances. Consultants and practitioners can prioritise their efforts based on newly identified CSF. The new revelation about CSF for LSS in quality 4.0 enriches theory as well. Social implications Developing skills based on newly identified CSF will help people in remaining employable in the era of automation, robotics and artificial intelligence which is otherwise ill-famed for destroying jobs. Originality value CSF for LSS using quality 4.0 is a new contribution. It differentiates CSF established earlier for conventional technologies. Moreover, many CSF are common for LSS and industry 4.0, therefore this study will also help in smoother adoption of industry 4.0/quality 4.0 in organisations.

Automated summary

This study validates critical success factors for Lean Six Sigma (LSS) using Quality 4.0 through empirical research and questionnaire method. The findings highlight the importance of Quality 4.0 related factors for LSS success, aiding enterprises in faster and more effective adoption of Quality 4.0 and seamless integration with LSS.
