Applications of lean thinking: a briefing document

This report has been put together by the Health and Care Infrastructure Research and Innovation Centre (HaCIRIC) at the University of Salford for the Department of Health. The need for the report grew out of two main simple questions, o Is Lean applicable in sectors other than manufacturing? o Can the service delivery sector learn from the success of lean in manufacturing and realise the benefits of its implementation?The aim of the report is to list together examples of lean thinking as it is evidenced in the public and private service sector. Following a review of various sources a catalogue of evidence is put together in an organised manner which demonstrates that Lean principles and techniques, when applied rigorously and throughout an entire organization/unit, they can have a positive impact on productivity, cost, quality, and timely delivery of services

Leanness and agility as means for improving supply chains. A case study on Egypt

Supply chain management has received greater attention from the academics and the practitioners, however the literature review lacks a comprehensive view for supply chain management practices and how its members should act to contribute to its overall success (Li el at., 2005). In this era, where the business organisations are working in several challenging threats and opportunities, greater attention is given to supply chain management. Nowadays, companies are always searching for means to improve their supply chains. The main aim of this research is to show "how leanness and agility approaches can be used within the same enterprise as complementary means for improving its supply chain". To achieve this research objective, the research has provided an assessment and summarised the literature on the supply chain management, lean thinking and agility thinking including their importance; their definitions; their practices and the relationship between lean and agility. The resulted proposed framework deduced from the literature has been applied in the Egyptian Manufacturing Business to show the relationship between the agility principles, lean principles, entity performance and the successful supply chain

Why small and medium construction enterprises do not employ six sigma

Six sigma (6σ) is a powerful business strategy which is aimed at increasing customer satisfaction and profitability by improving the quality of products and services. Many organisations have implemented 6σ and achieved significant levels of success. Successful implementation of 6σ leads to outcomes that would be welcome in the construction industry, given its reputation of suboptimal performance. The construction industry relies heavily on small and medium enterprises (SMEs). Any improvement in construction SMEs would lead to improvements in the construction industry as a whole. Against this background, a survey was undertaken to establish whether construction SMEs used 6σ and to identify factors affecting the adoption of this business strategy. It was found that none of the SMEs in the sample used 6σ. The reasons given for not employing 6σ, in descending order of importance, were: lack of knowledge about 6σ programme; lack of resources (human, time, money); 6σ programme not required by customers; other sufficient quality system in use; 6σ provides no perceived benefits; and end users not prepared to pay for 6σ programme. These reasons can be challenged when a critical analysis of innovation in the external environment within which construction SMEs operate, trends in the mode of delivery of construction industry products, trends in performance measurement in the construction industry and the flexibility of 6σ as a quantitative approach to managing quality. Construction industry stakeholders need to think about 6σ critically and make informed decisions about its role in the construction industry quality management agenda

Lean system implementation strategy and knowledge framework

Current research has exposed the fact that organisations in South Africa grapple with the implementation of lean systems. Lean systems affect the entire organisation and require strategies which link core and supporting processes from end-to-end. In many cases it requires the redesign of the supply chains’ supporting activities or processes that provide added value to the business processes of the organisation. Contemporary research postulates that to be successful, an organisation should have specific objectives when implementing a lean system. The objectives would ensure a smooth, rapid flow of materials and or work through a system. Primarily it compels management to perform a health-check or business capability performance gap analysis before attempting to formulate a lean implementation strategy. The objective of the paper based on topical research, is the development of a health-check. In developing a knowledge framework and measurement model, various tools were used for statistical analysis. The framework would assist organisations in identifying critical success factors during the implementation of lean. It addresses lean implementation strategy confirming the overall business improvement endeavour through value adding activities. An added advantage is that it would assist an organisation in performing a capability performance health-check before embarking on a lean or value adding project

A systematic literature review of hybrid approaches of lean, agile and six sigma philosophies in supply chain management

The purpose of this study is to critically review the current literature on hybrid approaches of lean, agile and six sigma applications in supply chain management. Lean, agile and six sigma are improvement philosophies; these are developed in the manufacturing industry. In the last two decades, the applications of these philosophies have received considerable attention in both the manufacturing and the service industries. This attention is evident in many published studies in different journals, showing challenges and limitations for adopting these philosophies, including the integrated lean six sigma (LSS) and lean-agile (legality or leagile) in the supply chain practices. However, studies on hybrid approaches of lean, agile and six sigma philosophies in the supply chain management using a systematic literature review are relatively lacking. With this motivation, this study aims to address such gaps in the supply chain management literature. More specifically, it focuses on exploring the challenges and limitations to identify the benefits of hybrid approaches in border supply chain management. In particular, to identify how those challenges and limitations impact on overall supply chain practices and performance. To this end, the final sample of 118 peer-reviewed articles was reviewed to constitute the knowledge base of the study. Therefore, this study critically reviewed and analysed previous theoretical and evidence-based literature on the key themes associated with the topic by using a systematic literature review. This study adopted a systematic literature review research methodology involving a three-stage review method. The three stages were (1) planning the review; (2) conducting the review; and (3) reporting and dissemination. This study presents the details of the literature search, outcomes of the search, subsequent analysis of 118 articles from 40 different journals, and contributions to knowledge, key findings and recommendations. This study is one of the first systematic literature reviews on hybrid approaches of lean, agile and six sigma philosophies, in particular reviewing the literature to explore to what extent hybrid approaches of these philosophies influence supply chain practices and performance in the context of various industries. None of the previous literature has critically reviewed the hybrid approach of lean, agile and six sigma philosophies in terms of challenges and limitations in the context of supply chain practices. This study adds to the existing literature by critically reviewing the literature on hybrid approaches of lean, agile, and six sigma philosophies, emphasizing challenges, limitations, and benefits of integrated approaches in the context of supply chain management for various industries. Based on a critical literature review, a conceptual framework is developed as the basis of integrated LASS philosophy for supply chain management

Subsequently, the hospital system should become far more competitive with supply chains having to react to these changes as patient demand becomes less predictable. Using a qualitative case study methodology, hospital managers are interviewed on a range of issues. Views on the development of the hospital supply chain in different phases are derived, and are used to develop a map of the current hospital chain. The findings show hospital managers anticipating some significant changes to the hospital supply chain and its workings as Patient Choice expands. The research also maps the various aspects of the hospital supply chain as it moves through different operational phases and highlights underlying challenges and complexities. The hospital supply chain, as discussed and mapped in this research, is original work given there are no examples in the literature that provide holistic representations of hospital activity. At the end, specific recommendations are provided that will be of interest to service to managers, researchers, and policymakers

Lean manufacturing adoption in the transport and logistics sector of Thailand - An exploratory study

This paper investigates the adoption status of lean manufacturing (LM) in the transport and logistics sector of Thailand. A survey questionnaire was design, validated and distributed among Thai transport and logistics companies. In total, 120 useable responses were received and analysed using descriptive statistics. The results of the study indicate that the implementation of LM is relatively high, with PDCA, 5S and root cause analysis being the most implemented LM approaches and tools. However, the LM’s implementation was found to be mainly contained within individual departments or improvement projects, rather than being a company’s wide strategy. Main challenges to LM implementation included: organisational structure of companies, misalignment between goals of individuals and their companies, and lack of sustainment of a lean culture. Main benefits were the ability to identify and reduce waste, increased productivity and better organisation of workstations. On the other hand, lack of understanding, knowledge and expertise in LM were the main reasons for not implementing it, plus the use of technology-based tools instead of LM. Non-LM companies showed interest in adopting LM in the future, with JIT, Kaizen and Six Sigma being the most likely to implement. This study is among the very first of its kind. It offers academics, researchers and practitioners interested in LM and/or the transport and logistics sector with some initial evidence of the adoption of LM in this industrial sector of Thailand

Green and lean sustainable development path in China: Guanxi, practices and performance

Globalisation has created both drivers and pressure for Chinese organisations to enhance their business performance as well as environmental performance. Green and lean practice is emerging as a critical approach for Chinese organisations to achieve sustainable development and improve organisational performance. By conducting empirical studies from 172 respondents on green and lean practice in different Chinese organisations, this research shows how green and lean practice affects organisational performance and how this association is affected by guanxi. The findings explain that guanxi between organisational partners improves the positive effect of green and lean practice on organisational performance. The results of this paper offer helpful insights into how managers should enhance their guanxi initiatives, in order to improve environmental and business performance over their supply chains. The paper also suggests the limitations of this research, as well as directions for future research
