Purpose To endure against the global rivalry, various organizations are espousing several quality melioration techniques, but most of them flunk to implement them in palmiest way; hence, to surmount the failure of implementation, it is very essential to identify and prioritize the impediments of the technique to be implemented. Lean Six Sigma (LSS) has evolved as one of the most efficacious technique implemented by organizations. The purpose of this paper is to identify and prioritize the barriers of LSS for its productive implementation. Design/methodology/approach The study initiates from conducting a literature review of peer-reviewed articles concentrating on LSS barriers. The barriers are identified from literature as well as opinion from industry experts. These barriers are categorized underneath the canopy of five major criteria. The final elite barriers are prioritized and stratified by employing the fuzzy analytical hierarchy process approach. Findings The present study identifies 27 critical barriers that obturate the palmy LSS implementation. Further prioritization of these barriers will help the practitioners to develop the strategies to tackle the barriers. Research limitations/implications The LSS barriers are identified through the literature search and opinions from industry experts, while a survey can be conducted in order to incorporate more barriers related to manufacturing concerns. Originality/value The main contribution of this paper includes identification of LSS barriers and later prioritizing them to project their intensity in order to make the practitioners comfortable to handle the LSS implementation issues.

Process Failures

Purpose This paper aims to identify and reduce possible process failures occurred in warehouse. Design/methodology/approach This research used risk analysis method FMEA combined with fuzzy-analytical hierarchy process (AHP). Design FMEA will direct the failure mode or failure of components into levels and will use it to analyze the product before it used in manufacturing processes. Design FMEA has a major point on the failure mode that caused inefficiency in the design while fuzzy-AHP used to reduce subjectivity in the weighting process. Findings The results show that high inventory is the dominant factor that must be controlled by the company to prevent the risk of failure processes in the warehouse, followed by the number of stocks that do not match with existing records, and misplacement of machines and/or materials. Originality/value This research used risk analysis method FMEA combined with fuzzy-AHP to identify and reduce the possible process failures in warehousing.

Practical Implications

Purpose The purpose of this paper, builds on previous studies that explored the research patterns over 15 years, is to consider the current status of the integration of Lean and Six Sigma. More specifically, this research addresses whether Lean and Six Sigma are stronger together and explores the reasons why Lean researchers and practitioners may be less likely to integrate Six Sigma in their work. Design/methodology/approach The research utilises a survey of 25 established and respected academics and practitioners from 16 countries. The questionnaire is analysed using a direct content approach and coded in NVivo. Findings The findings suggest that challenges may lie in the perception and understanding of statistics as well as short-term rather than long-term focus on improvement. The findings also suggest that academics and practitioners believe that Lean Six Sigma has developed over time and will continue to develop and improve as a methodology rather than being replaced with a new methodology. Research limitations/implications The survey has a sample size of 25, albeit all respondents are established and very experienced practitioners and academics. Practical implications For organisations that are introducing or refreshing their continuous improvement initiatives, this research identifies some of the challenges and provides the opportunity to address them to maximise the opportunities for success and sustainability. Originality/value The value of this paper is that it further addresses the debate over the integration of Lean and Six Sigma for many organisations which still employ Lean alone, but beyond this it explores how they will continue to develop and whether they are a permanent edition to the quality management landscape or a transition to something else.

Purpose The paper aims to incorporate the relationship of reverse logistics into the economic, environmental, and social sustainability, known as triple bottom line and developed a framework for reverse logistics performance evaluation. Design/methodology/approach The performance measures, based on triple bottom line approach, were selected, and fuzzy analytical hierarchy process and extent analysis approach was applied for estimating the weights, global weights of performance measures and hence, the reverse logistics performance index. Reverse logistics performance of three electronic companies were evaluated and compared for the demonstration of the methodology. Findings The results show that economic performance has highest performance index followed by environmental performance and social performance. “Recapturing value” and “return on investment” from economic, “minimum energy consumption” and “optimum use of raw material” from environmental and “community complaints” and “customer health and safety” from social perspective have higher performance indexes. Over all, “reduced packaging”, “use of recycled material” and “employee benefits” show very poor performance indexes. Research Limitations/implications The study will provide useful guidance to the academicians and practitioners for evaluating, improving and benchmarking the reverse logistics performance. Originality/value The analysis adds to the very few studies on triple bottom line aspects of reverse logistics and its performance evaluation. Also, fuzzy analytical hierarchy process and extent analysis is used first time being an efficient tool to tackle the fuzziness of the data involved in performance evaluation.

Learning Points

Purpose This paper is based on a single case study carried out as part of a change programme but is used as a reflective tool to draw on some of the wider organisational learning which can be considered when implementing, reviewing or re-energise a Lean Six Sigma (LSS) Programme. The paper aims to discuss this issue. Design/methodology/approach A case study approach has been used and referenced throughout the paper with references to literature to support the wider learning points drawn which are then applied to any continuous improvement (CI) programmes. Findings The paper presents a range of learning points which are drawn from a successful deployment of LSS within a change project carried out as part of an overall programme in Scottish policing services. Research limitations/implications The points are drawn from a single case study which was deployed within a wider change programme and is supported by wider literature but is used as a vehicle for informing strategic considerations within an organisation. Originality/value This case study is drawn from policing services in the public sector which alone is an area that has not been significantly studied. It is used to explore wider implications in terms of strategic alignment, organisational performance and project management and presents the argument that the design of a CI programme is much wider than the implementation of LSS itself.

PT. PQR merupakan perusahaan yang bergerak dalam produksi bata ringan. Bata ringan diproduksi menggunakan sistem Autoclaved Aerated Concrete (AAC). Dari hasil pengamatan di perusahaan, produk bata ringan sering mengalami kerusakaan karena jatuh dari pallet saat dipindahkan menggunakan hand lift. Hal ini disebabkan oleh jauhnya jarak perpindahan antara lantai produksi dan gudang produk, sehingga operator kesulitan dalam proses pemindahan. Tujuan dari penelitian ini adalah untuk merancang ulang tata letak fasilitas dengan menggunakan pendekatan metode Fuzzy Analytical Hierarchy Process (Fuzzy AHP) disertai dengan metode Systematic Layout Planning (SLP) untuk mendapatkan rancangan yang efisien. Hasil pembobotan matriks berpasangan menunjukkan tenaga kerja adalah variabel yang memiliki bobot kriteria tertinggi sebesar 0,2735. Setelah dilakukan analisis didapatkan bahwa kedekatan antar departemen sangat dipengaruhi oleh perpindahan tenaga kerja (operator) antar departemen. Dari hasil analisis, dirancang activity relationship chart (ARC) untuk mendapatkan kedekatan antar departemen, kemudian dirancang layout baru berdasarkan pertimbangan luas masing-masing departemen. Hasil rancangan ini dibandingkan dengan rancangan awal, sehingga diperoleh pengurangan jarak sebesar 165,01 m. PT. PQR is a company engaged in the production of lightweight bricks. Lightweight bricks are produced by using the Autoclaved Aerated Concrete (AAC) system. From the observations in the company obtained results thatight brick products often experience damage due to falling from the pallet when moved using a hand lift. This is due to the distance between the production floor and the product warehouse, so operators have difficulty in the process of moving. The purpose of this study was to redesign the layout of the facility using the Fuzzy Analytical Hierarchy Process (Fuzzy AHP) with the Systematic Layout Planning (SLP) method to obtain an efficient design. The paired matrix weighting results showed that labor is a variable that has the highest weight of 0.2735. After an analysis was conducted, it was found that the closeness between departments was strongly influenced by the movement of labor (operator) between departments. The results of analysis, a relationship chart (ARC) activity was designed to get closeness between departments, then a new layout was designed based on the broad consideration of each department. Furthermore, the results of this design were compared with the initial design, such that obtained a distance reduction of 165.01m .
