The goal of this paper is to effectively analyse and monitor hospital LOS to help improve healthcare quality. Given the fact that abnormal LOS results in increasing cost for all stakeholders, this study proposes a new framework based on cross-industry standard process for data mining framework (CRISP-DM) and Six Sigma methodology, including control charts for monitoring and improving LOS. The utility of the proposed method is demonstrated through a case study involving 11,722 internal medicine patients at a large hospital in Southwest Virginia. Outcomes of this study have potential to support decision makers at hospitals to detect abnormal LOS by identifying effective and efficient ways to minimise it, thereby reducing costs.","PeriodicalId":35430,"journal":{"name":"International Journal of Six Sigma and Competitive Advantage","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2019-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74484641","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Six Sigma is considered an essential methodology approaching for product and process improvement. The methodology applies five Six Sigma phases, define, measure, analyse, improve and control (DMAIC) for resolving the respected problems which demonstrated a lot of successful stories for decades. This paper is an attempt to introduce new model of manufacturing improvement and innovation which mainly based on DMAIC phases. Dynamic sigma-TRIZ solution model is proposed to enhance the opportunity of deploying improvement and creating innovative solutions in manufacturing process whereas that dynamic sigma-TRIZ principle matrix database was created from 107 examined projects and also keep updating regularly once additional problems or opportunities got resolved. The paper discussed the real-life cases when dynamic sigma-TRIZ solution model was implemented successfully in resolving manufacturing problems in different aspects.","PeriodicalId":35430,"journal":{"name":"International Journal of Six Sigma and Competitive Advantage","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2019-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89700571","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Specification limits and control limits are treated as independent entities until modified control limits are proposed which stress the need for control limits to keep satisfying specification requirements as well. High quality processes always attempt to provide products right the first time where specification requirements are checked for controlled processes. This calls for a strong link between control limits and specification limits. A house of quality-like representation can be used to describe such a link. It is preferred to intertwine the features of specification limits with the construction of control limits to achieve right the first time. In this paper, a critical review on specification limits and control limits is made from the perspective of Six Sigma quality and the need for a strong bond between the two is stressed.","PeriodicalId":35430,"journal":{"name":"International Journal of Six Sigma and Competitive Advantage","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2019-03-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76154911","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Lean and Six Sigma are two different tools which are used in combination for operational excellence. It provides a framework for waste reduction and elimination of non-value added activities along with variability reduction tools. Lean tools reduce the waste and non-value adding activity and enhance the effectiveness of equipment, tools and machines. Six Sigma tools helps in decision making based on data which finally reduce the variability in the process. In this case study, Lean Six Sigma framework is implemented to reduce the defects which occurred during the manufacturing process in a bulb manufacturing company in India. The framework used combines the lean as well as Six Sigma tools to mitigate the defects and increase the customer satisfaction.","PeriodicalId":35430,"journal":{"name":"International Journal of Six Sigma and Competitive Advantage","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2019-03-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85246692","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A customer wants to buy a product at the lowest possible price without compromising quality. To overcome this problem, the role of lean manufacturing has been introduced. Lean manufacturing is capable for waste reduction without compromising both quality and productivity. To fulfil this purpose, 13 practices of LM have been identified through literature review and expert opinions from academics and industry experts. To identify the cross impact of LM practices, an interpretive structural modelling (ISM) approach have been utilised to find interrelation between these LM practices using MICMAC analysis. Results of this analysis are highly beneficial towards the implementation in industries getting lean.","PeriodicalId":35430,"journal":{"name":"International Journal of Six Sigma and Competitive Advantage","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2019-03-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77337817","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Cost of poor quality has gone up significantly with the traditional approach of controlling the quality. Traditional approaches are not very effective in solving chronic quality issues. In order to meet up the global expectation, organisation needs to explore effective and fast approaches which utilise various advanced techniques to solve chronic quality issues. This paper demonstrates the systematic use of Shainin techniques to solve chronic quality problem of noise from automotive transmission. Transmission is a complex system having many subassemblies, components and each component in turn has multiple parameters contributing to noise makes transmission noise an extremely complex multi-factorial problem. Shainin techniques known as component search and paired comparison have been used sequentially to identify components and subsequently the parameters of components contributing to the noise in the transmission.","PeriodicalId":35430,"journal":{"name":"International Journal of Six Sigma and Competitive Advantage","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2019-03-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87745700","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
