Purpose The purpose of this paper is to improve the operational excellence of public sector services such as construction, telecommunication and health care. To achieve this endeavor, the study explores the structural attributes and obstacles in the public services and develops a Green Lean Six Sigma (GLSS) model for the public sector. Design/methodology/approach The study involved two stages: first, structured literature reviews; second, a focus group study involving Black Belts and supply chain practitioners. Using the results from the literature reviews and focus group study, the researchers have developed a Green Lean Six Sigma (GLSS) model for the public sectors. Findings Black belts and supply chain practitioners have identified the success in deploying Lean Six Sigma with green supply chain management. This leads to eradicating the obstacles faced by the public sector, leading to process improvement. Practical implications This study proposed an approach for developing a GLSS model for the public services, which can be applicable for other public service organizations. Originality/value The current paper presents a predictive model for process improvement in the public sector by integrating green supply chain management with Lean Six Sigma.
