To analyse the overall performance index score of an automotive component manufacturing organisation that has implemented Lean Six Sigma 4.0 (LSS4.0) using neutrosophic DEMATEL (Decision-Making Trial and Evaluation Laboratory).
Performance measurement is a complex process as it relies upon many quantifiable and non-quantifiable factors. In this study, the overall performance index score of (LSS4.0) is analysed using neutrosophic DEMATEL. Five main criteria and 62 sub-criteria are identified from existing studies using a structured literature review method, sub-criteria are grouped with appropriate main criteria based on expert panel decisions. Organisational performance was evaluated based on data collected using questionnaires and real-time data of few metrics. People, process, organisational, technical and operational criteria are the main criteria considered for evaluation of the organisation’s performance.
Results of the study indicated that technological and infrastructural development has a vital role in improving the overall performance of an organisation.
The study is being done with reference to automotive component manufacturing industry. Hence, the resulting inference has practical validity. On academic front, the study confirms an increase in organisation’s overall performance through the adoption of integrated LSS4.0 manufacturing method, and proposed performance management system model facilitates real-time reviewing of performance metrics.
Comprehensive performance analysis of LSS 4.0 using neutrosophic MCDM method is the original contribution of the authors.
