Since then, leading U.S. companies have gained significant financial and non-financial benefits/results from the implementation of Six Sigma projects. Despite Six Sigma popularity, some companies have failed to gain quantifiable net financial benefits/results from Six Sigma implementation. In the process of Six Sigma implementation, vital components are critical factors and key ingredients for the success of Six Sigma projects because if these vital components do not exist, Six Sigma projects have little chance of success. Thus, this paper identifies most influencing and least influencing vital components. The results are generated from a survey conducted in U.S. Fortune 500 companies employing descriptive statistics. Based on the data analysis, ＂leadership commitment to Six Sigma＂ was the most influencing vital component and ＂overall, training on Six Sigma to reduce employee turnover＂ was the least influencing vital component.展开更多

Chemical administration （@ 30 mg/dm3） resulted in phosphate precipitation from water column concomitant with inactivation in sediments, under specific pH range and/or redox regime. The alum-lime combination dosing wrought the maximum reduction in orthophosphate （65.6%） and soluble reactive phosphate （71.9%） in water plus the utmost increment in sediment-P （0.257 ppm）. The inactivated P forms typically exhibited a downhill concentration gradient with highest sequestration in the uppermost sediment stratum. Ironbound P displayed the highest mobility while calcium- and aluminum- bound P behaved almost immune to internal feedback dynamics. The combo-treatment was established as the most effective phosphate scavenging and confiscating agent, to be adopted as chemical remediation regime for de-eutrophication, restoration and rehabilitation of the water body.展开更多
