“…SS has management and technical components; the management focus is on identifying process metrics, setting goals, choosing projects, and assigning people to work on projects, while technical side is focused on enhancing process performance by reducing variation (Hu et al 2005). In relation to SS training, it mainly involves three groups of T&T sets about team, process and statistic.…”

“…Six-Sigma is named after the process that has six standard deviations on each side of specification window (Chen et al, 2007). The discipline of Six-Sigma is particularly good for organizations seeking both bottom line improvement and defects reduction (Hu et al, 2005). In a Six-Sigma project, the team's problem solving efforts depend heavily on the use of a stepwise problem solving DMAIC (Choo et al, 2007).…”

Six-Sigma approach is a systematic and scientific operations management methodology aimed at achieving major enhancements in production process through the elimination of waste. In this case, a casting unit manufacturing cylinder blocks has been selected which was experiencing a rejection rate as high as 30% due to formation of blowholes, other than the surface. The main objective of this paper is to identify various causes of occurrence of blowholes and recommend corresponding remedies to counter these defects by systematic implementation of DMAIC cycle. Both preventive and corrective actions have been recommended to reduce the blowholes and overall improvement is validated through two-proportion test. Results of investigation demonstrated the net significant reduction of blowholes defect from 28,111 to 9,708 parts per million, which results in the net annual savings of INR 12,56,640.

“…The Improve Phase eliminates defects by fixing root causes of process. Lastly, the Control Phase monitors the improvements to ensure they are maintained . The purpose of this study is not to assign what tolerance values others should use, but to show how DMAIC framework can be used to customize the patient‐specific QA by designing tolerances.…”

“…Lastly, the Control Phase monitors the improvements to ensure they are maintained. 11,12 The purpose of this study is not to assign what tolerance values others should use, but to show how DMAIC framework can be used to customize the patient-specific QA by designing tolerances. The emphasis of our work is on the improvement of process capability by balancing quality; where possible, tolerance may be designed to meet the functional requirements of the patient site-specific range QA in proton therapy.…”
