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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

Literature reviews are a pervasive aspect in research. An ever mounting field such as Lean Six Sigma requires a perpetual touch on the subject to accentuate insights that can be researched about. The purpose of this paper is to address the published literatures in the field of Lean Six Sigma through multiple criterion for an enhanced understanding of the subject matter through summarizing its current trends, uncovering existing literature gaps and revealing opportunities for future research in the field.

The literature review on Lean Six Sigma field spans around 17 years that includes peer-reviewed journals from management, business, engineering, healthcare, manufacturing, military among the many disciplines. The study uses a content analysis approach in which several dimensions of the literature were analysed: purpose or focus of study, years of publication, journal name or publications, methodologies, theories used, country of study, industry sub-sectors, active authors in the field, critical success factors, barriers and challenges and the most contribution of Lean Six Sigma papers by universities.

Eleven important findings from the analysis were summarized among them; the field of Lean Six Sigma had begun to grow significantly since the new millennium particularly after the 2004-2007 or 2008 period; standalone concepts of Lean and Six Sigma are highly researched compared to the integrated concepts; large proportion of perspective, conceptual and descriptive based studies; lack of empirical validity on the fusion between Lean and Six Sigma; lack of theoretical based studies, etc.

The study is limited to 102 journals in commonly searched databases in the subject matter which produced 261 journal papers. This study seeks to broaden the summary of studies done under the keyword “Lean Six Sigma”.

The review analysis uses a content analysis approach in search of valuable gaps in existing research. The study found 261 papers from 102 journals that were published over the past seventeen years (2000-2016). This paper provides scholars, practitioners and managers with insights on the present trends and focus of Lean Six Sigma in addition to what else are lacking in the subject matter, which could pave the way for future research and practical endeavours.
