The implementation of lean Six Sigma in financial services organizations

Abstract: Purpose – The purpose of this paper is to obtain pertinent information pertaining to benefits accomplished, main difficulties felt, and key lessons learned in the implementation of lean Six Sigma (LSS), which are likely to be helpful to financial services organizations wanting to implement the same tool.Design/methodology/approach – This paper reports the results of a case study from a financial services organization which has begun the implementation of LSS methodologies ten years ago, in the pursuit of service excellence.Findings – The benefits derived from LSS implementation, such as lowering the operational costs, improving processes and product quality, increased efficiency, which leads to the increase of productivity, the agility and versatility obtained by the organization, vastly outweigh the costs. At an international level, there are cultural differences pertaining mainly to internal resistance and openness to change.Research limitations/implications – This work focuses on a specific case study....

Multi‐faceted views on a Lean Six Sigma application

Abstract: Purpose – Lean and Six Sigma observers, researchers and managers are awaiting the next step, which many feel could take the form of a combination of the two concepts, known as Lean Six Sigma. The purpose of this paper is to explore an application of Lean Six Sigma in practical improvement work, as a way of identifying factors of importance for improving future Lean Six Sigma applications. Design/methodology/approach – The empirical study was conducted through interviews, meetings, document analysis and observations over a period of four months. Findings – The findings of this study suggest it is unfeasible to apply one standardised approach to improvements in one company. Continuous smaller improvements and larger improvement projects demand different formulas. It is appropriate to use Lean and Six Sigma in parallel but this should be done through clever cross-fertilisation, such as taking variations in project complexity into consideration. Research limitations/implications – This paper shows one way of working with an improvement initiative in one particular company. It does not propose that this is the only way to combine Lean and Six Sigma nor does it suggest universal applicability. Further research on other possible combinations would be valuable. Practical implications – This paper provides an outline of how to structure a combination of Lean and Six Sigma. This could provide valuable insights to managers who wish to structure their improvement processes depending on the type of problem at hand. Originality/value – This paper expands the theoretical foundation for combining Lean and Six Sigma by studying and analysing a practical application of the concept. As a result, it provides new factors of importance for successful Lean Six Sigma applications, such as having a clear structure that guides the company in terms of what components of Lean Six Sigma to apply and what competences to involve in various projects, depending on the scope and complexity.

Critical success factors of Lean Six Sigma for the Malaysian automotive industry

Abstract: Purpose – The objective of this paper is to explore the critical success factors (CSFs) for Lean Six Sigma (LSS) in the Malaysian automotive industry.Design/methodology/approach – Structural equation modeling (SEM) was employed to test the model drawing on a sample of 252 Malaysian automotive organisations. Exploratory factor analyses (EFA), confirmatory factor analysis (CFA), and reliability analysis empirically verified and validated the underlying items of CSFs of LSS.Findings – The results of EFA, CFA, and reliability analysis show that two items for supplier relationship are recommended to be excluded from the analysis. The result indicates that LSS has identified 40 items as compared to the original questionnaire which had 42 items. Based on the survey of empirical data, the two factors of leadership and customer focus have been shown to be the extremely important factors for LSS implementation in the Malaysian automotive industry.Research limitations/implications – Firstly, this survey is based onl...

Lean Six Sigma: a categorized review of the literature

Abstract: Purpose – Literature reviews in the field of Lean Six Sigma (LSS) are often substantially less stringently portrayed than other empirical research. The purpose of this paper is to lucubrate on clarifying emerging aspects, trends and importance of LSS through reviewing the published literature over multiple parameters for a ameliorating and trenchant view. Design/methodology/approach – In the present study, a literature review of LSS articles is carried out over the time horizon of 14 years from referred peer-reviewed journals in business and management disciplines, information systems and computer science, engineering, healthcare, etc. While carrying out the literature review, various distinct dimensions are considered, such as publication years and journals, countries, research design, research type and application sector within industries. A descriptive evaluation of the literature body is followed by gap identification and future research opportunities. Findings – LSS research is growing rapidly, covering various disciplines and domains with a great focus on LSS tools and techniques; empirical research is dominant with more emphasis on case study approach; and growing gap between manufacturing- and service-focused articles implies return of LSS to manufacturing as its initial base. Originality/value – The review analysis entirely focuses on descriptive statistics of empirical research in LSS. The sample size includes 189 shortlisted articles in 58 journals published over a time span of 14 years (2001-2014). The paper provides both academicians and practitioners a better panorama to understand the present status of LSS for pursuing rigorous LSS research through explicating chronological emergence, challenging themes, dominating research types and application areas in LSS.
