Purpose – Lean Six Sigma (LSS) is a continuous improvement methodology that aims to reduce the costs of poor quality, improve the bottom-line results and create value for both customers and shareholders. The purpose of this paper is to explore the critical failure factors for LSS in different sectors, such as manufacturing, services, higher education, etc. Design/methodology/approach – The following research is based on a systematic literature review of 56 papers that were published on Lean, Six Sigma and LSS in well-known academic databases from 1995 to 2013. Findings – There are 34 common failure factors of LSS cited in this paper. There are some common factors for failure, such as a lack of top management commitment and involvement, lack of communication, lack of training and education, limited resources and others. Many gaps and limitations are discussed in this paper and need to be explored in future research. Originality/value – The paper is one of the first systematic literature reviews to explore the critical failure factors of LSS and discuss the top failure factors from different angles, i.e. countries’ evolution, organisations’ size (small- and medium-sized enterprises and large organisations) and industry nature.

AbstractPurpose -The purpose of this paper is to explore the most common themes within Lean Six Sigma (LSS) in the manufacturing sector, and to identify any gaps in those themes that may be preventing users from getting the most benefit from their LSS strategy. This paper also identifies the gaps in current literature and develops an agenda for future research into LSS themes. Design/methodology/approach -The following research is based on a review of 37 papers that were published on LSS in the top journals in the field and other specialist journals, from 2000 to 2013.Findings -Many issues have emerged in this paper and important themes have cited which are: benefits, motivation factors, limitations and impeding factors. The analysis of 19 case studies in the manufacturing sector has resulted in significant benefits cited in this paper. However, many gaps and limitations need to be explored in future research as there have been little written on LSS as a holistic strategy for business improvement. Practical implications -It is important for practitioners to be aware of LSS benefits, limitations and impeding factors before starting the LSS implementation process. Hence, this paper could provide valuable insights to practitioners. Originality/value -This paper is based on a comprehensive literature review which gives an opportunity to LSS researchers to understand some common themes within LSS in depth. In addition, highlighting many gaps in the current literature and developing an agenda for future research, will save time and effort for readers looking to research topics within LSS.

Purpose – The purpose of this paper is to contribute to the body of Lean Six Sigma (LSS) knowledge within the field of higher education institutions. The paper will review the initial phase of an implementation and highlight future challenges of applying the LSS method in a complex transactional environment. Design/methodology/approach – The observations presented in this paper originate from rolling out a large LSS implementation at a recently established university. The paper is supported with secondary data from literature. Findings – The implementation of LSS methodology at King Abdullah University of Science and Technology has resulted in improvements in business processes and efficiency. This has been achieved through project execution and training programs. Approximately 350 staff members have completed awareness training, 50 yellow belts and 150 green belts have been trained, and the first round of seven black belts have completed training of which two have completed certification. Research limitations/implications – This paper is based on an empirical study of a single instance and the authors’ experiences as practitioners. Originality/value – This paper is the first description of what is believed to be one of the largest implementations of LSS in higher education.

Purpose Although the popularity of the Lean Six Sigma (LSS) methodology has illustrated many benefits over the years for those organisations who have implemented it, this strategy has received less attention in developing countries. The purpose of this paper is to critically assess the current status of LSS implementation in Saudi Arabian organisations. Design/methodology/approach This research is based on a descriptive survey questionnaire which has been derived from two systematic literature reviews. The survey was distributed to 400 organisations in Saudi Arabia using Qualtrics online software. In total, 146 responses were received where 102 responses were completed and analysed. Findings The findings of the survey highlighted that the implementation of LSS is still in the early stages in organisations within Saudi Arabia. This was clearly shown by many factors such as years of deploying LSS, LSS infrastructure, level of awareness of LSS, impact of LSS on business functions and so on. Research limitations/implications The primary limitation of this study is that data has been collected from an online survey and therefore no deeper insights could have been captured from the survey. This calls for future research to be undertaken by executing semi-structured interviews in selective organisations within Saudi Arabia. Originality/value This paper contributes to the current status of LSS in Saudi Arabian organisations. It also gives recommendations to guide the future of LSS in Saudi organisations by comparing LSS literature with best practice.
