Integration of Blockchain and Lean Six Sigma approach for operational excellence: A proposed model

Research output: Contribution to journalArticlepeer-review


Purpose: This research work aims to explore the potential application of Blockchain technology in Lean Six Sigma (LSS) project through a proposed Blockchain-LSS (BLSS) model. The proposed model can tackle real-time problems in information sharing, transparency, and traceability in every stage of the LSS project.

Design/methodology/approach: The scoping review approach is used to develop the integrated model of the Blockchain-LSS approach for operational excellence. The proposed model is validated through expert's input which is collected by a questionnaire survey method.

Findings: The prime function of the proposed BLSS model is the information sharing among the project team and real-time monitoring, transparency, traceability, and immutability in the DMAIC (Define-Measure-Analyze-Improve-Control) phase. The proposed model also consists the information about the role of Blockchain features at each phase of the LSS project. The project team and industry employees can trace the success of the project at every moment, resulting in trust buildup and the elimination of fake data. Moreover, there would be no disputes among various sections/shops of the plant and employees to share the real information.

Practical implications: This paper provides guidelines to practitioners and managers for integrating the LSS approach and Blockchain. The Blockchain helps managers and practitioners in better data traceability and transparency, monitoring of data as well as more sustainable LSS project management.

Originality/value: This is the first research attempt that developed an integrated model of blockchain and LSS approach to maintaining the immutable records of assets in projects and targeted industry 4.0.
