Purpose The purpose of this paper is to empirically assess the impact of integrated lean and green practices on the sustainable (environmental, economic and social) performance of a hotel supply chain. Design/methodology/approach Literature review and previous exploratory studies were used to develop a hypothesized model that characterizes the integrated lean and green (LeGreen) impact on supply chain sustainability. A case study of a large sample of the UAE hotels is used to collect and analyze empirical data, validate the measurement model and test study hypotheses using structural equation modeling (SEM). Findings The results showed that three major lean techniques (Kaizen, quality and productive maintenance) and three green techniques (health and safety, waste disposal and green certifications) have substantial impact on the sustainable performance of hotel supply chains. Further results revealed that LeGreen impacts are complementary. Lean techniques have the highest impact on the economic performance of the hotel supply chain and the least impact on the environmental performance. Green practices, on the other hand, have opposite impacts. Research limitations/implications Although the study findings may vary in different contexts, study methodology and measurement model can be adapted to assess the LeGreen impact on the sustainable performance of hotel supply chains, as well as other service industries such as banking and health care. Practical implications The proposed assessment model is expected to be of great value toward the effective implementation of LeGreen practices across hotel supply chains in the UAE and globally. The study findings also provide guidelines for practitioners within the hospitality sector to undertake the proposed model and to adapt it for assessing and enhancing sustainable performance in other sectors of the service industry. Originality/value There is a growing emphasis by practitioners and academics on measuring the impact of LeGreen on the sustainable performance of service supply chains. However, the assessment of LeGreen impacts within the context of a hotel supply chain remains unexplored with a scarcity of comprehensive assessment frameworks. This study aims to fulfill this gap in literature and provide directions for researchers to expand the proposed model and to further analyze the integrated lean-green impact on the sustainability of supply chains of hotels and the service industry.

Purpose The purpose of this paper is to develop a framework for identification, categorization and prioritization of lean techniques adopted in a hotel supply chain. Design/methodology/approach A survey tool is used for the identification of lean techniques that are relevant to a hotel supply chain. The targeted sample includes experts from 50 four- and five-star hotels in the United Arab Emirates (UAE) that confirmed experience in implementing lean practices across hotels supply chain. A Supplier-Inputs-Process-Outputs-Customers (SIPOC) chart and experts’ opinion are used to allocate and categorize the identified lean techniques across the construct of the hotel supply chain. Finally, analytical hierarchy process (AHP) is used to prioritize the criteria and sub-criteria of adopted lean techniques. Findings Study results have identified six main categories of lean practices and 19 specific lean techniques as relevant to a hotel supply chain. The identified categories include JIT, Kaizen, Quality, Inventory, Maintenance and Standardization. The study found that JIT and Kaizen take the top priority among the identified categories of lean practices. In line with that, on-time service to customers, effective improvement system and on-time delivery from suppliers were found to be the three most relevant lean techniques to a hotel supply chain. Research limitations/implications The study has targeted a representative sample of hotels with experience in implementing lean practices. Study findings have several implications to researchers and practitioners for effective adoption of lean techniques within a hotel supply chain. However, the accuracy and credibility of results obtained from this research including SIPOC allocation and lean categorization are highly dependent on the accuracy and credibility of collected empirical data from surveyed hotels within the study context. Results of AHP prioritization also depend on the credibility of judgements made by the hotels’ supply chain experts. Practical implications The study provides the hospitality industry with a structured approach that can help in a prioritized adoption of most relevant lean techniques across the hotel supply chain to reduce wastes, create value, increase efficiency and improve the service level. Study findings can be used by hotel management to direct and focus the effort of lean capacity building, resources allocation and implementation plans. Originality/value Limited research is available on lean management in the context of a hotel supply chain. Also, most of the previous research is focused on lean impacts, while academics and practitioners agree that the identification and prioritization of most relevant lean techniques is crucial to the successful implementation of lean management for waste reduction and value creation. This research addresses this important issue in hotel supply chains and proposes a structured approach for effective lean adoption.

Purpose -The purpose of this paper is to investigate the application of lean construction practices in the construction industry and develop a practical and applicable framework that incorporates Six Sigma rating into the best practices of lean construction. The objective is to help the industry reduce waste and cost, increase effectiveness, and improve quality. Design/methodology/approach -A generic yet practical framework of lean construction is developed using the guidelines of project lean delivery system developed by the Lean Construction Institute (LCI). Applicable lean techniques and Six Sigma rating are integrated into the developed framework. A cyclical look-ahead planning and execution approach is used to implement the lean construction techniques. A set of Lean Six Sigma (LSS) performance indicators is defined to measure performance, set target threshold values, and guide improvement actions. A case study of the construction industry in Abu Dhabi (AD) is used to clarify the proposed approach and identify its key practical aspects. Findings -Analysis of wastes in AD construction industry reveals 27 types of construction wastes. These wastes were categorized into the seven types of wastes. Defects (errors and corrections) are found to be the most common type of construction waste in the surveyed companies. This calls for integrating Six Sigma rating into the proposed lean construction framework. The other common types of wastes are overprocessing and delays. Lean project management is focused on assessing a set of key performance indictors (KPIs) at the end of each "look-ahead" period. First lean practices are employed during the period and Sigma Rating is assessed at the end of the period along with other KPIs. The proposed LSS-KPIs were able to measure progress and guide improvement.Research limitations/implications -The credibility of the research findings is dependent on the accuracy and reliability of collected data from construction companies. Implementing lean construction techniques within a look-ahead period is not expected to achieve significant project gains in terms of quality, speed, and cost without adopting the overall lean construction framework. Social implications -The work of construction companies largely contributes to the quality and safety of public and society at large through residential and commercial buildings, transportation, and infrastructure projects. Lean construction practices and Six Sigma rating positively impact these important aspects and often result in reducing waste and costs, improving safety, and saving energy resources in construction projects. Originality/value -Research significance stems from the focus on increasing the effectiveness of the construction industry. Research contributions include the development of an applicable lean construction framework that integrates lean construction practices with Six Sigma rating. This contributes to the effort of applying Lean Six Sigma (LSS) in the vital field of construction. This research prescribes a systematic appr...
