Purpose Today, manufacturing companies are facing a fierce competition and are under great pressure to cut costs for survival in the market. So emphasis is given to enhance quality, minimize waste, customer delight and increasing productivity through reduction in wastage of resources. But, most companies hesitate to implement all measures simultaneously to acquire lean manufacturing because of some practical/ capital constraints. Therefore, the purpose of this paper is to develop a phase-wise approach to implement lean manufacturing. Design/methodology/approach The paper opted for an exploratory study using the qualitative flexible system methodology framework proposed by Sushil (1994) and options field methodology proposed by Warfield (1982, 1990) including rigorous group discussion comprising the employees representing middle and senior management with productivity improvement backgrounds. The response of experts was recorded using a specially designed instrument in the light of the parameters suggested in group discussion. The measures/ actions were arranged in the decreasing order of their cumulative score. Findings The paper provides a phase-wise approach to implement lean manufacturing. Mixed approach is preferred over the other three approaches to implement lean manufacturing. Thirty measures/actions contributing to mixed approach are identified to implement lean manufacturing in three phases. A three-phase approach is developed: 10, 14 and six measures in the first, second and third phases, respectively, are identified to implement lean manufacturing after considering the practical constraints faced by the companies. Research limitations/implications All the measures/actions suggested to implement lean manufacturing are focused on the engineering manufacturing industry. Thus, the research results may lack generalizability and are limited to engineering manufacturing industry. The model developed in this research is based upon experts’ opinions. The experts’ opinion may be biased. The results of the model may vary in the real-world setting. Practical implications The present paper provides guidelines to practitioners for implementing lean manufacturing in phases. Hopefully, this study will motivate the firm’s management for implementing lean manufacturing and limiting the effect of practical constraints and scarcity of resources.

Purpose The purpose of this paper is to examine the structural relationship model among transformational leadership, sustainable leadership (SL), lean manufacturing practices and sustainability performance. Design/methodology/approach The data were collected from the middle and senior managers working in small and medium enterprises of Thai manufacturing industry. Regarding the quantitative approach, the data were collected by means of survey from 598 respondents from 374 companies. Qualitative data were collected from 40 participants by participant observation, non-participant observation and in-depth interview. Findings The model reported that lean manufacturing has a partial mediate effect on the relationship between transformational leadership and sustainability performance, and between SL and sustainability performance. The structural model is different in automotive and nonautomotive companies, and the structural model is different among the companies which implemented lean program for less than five years and above five years. The data from in-depth interview informed that lean practices are appropriate for automotive industry though with less implementation in other industries. Firms pay most attention on customer involvement with some attention on employee and supplier involvement. Managers give advices and exchange ideas with their followers rather than inspiring and giving opportunities to make decision. Research limitations/implications The findings may also enable Thai managers to realize that lean practices are appropriate for any industry. The first thing to do before launching lean program to all process is that the company should buy-in the understanding of managers about lean concept and implementation. Willingness with well understanding and realizing importance of lean program will lead to superior results, especially operational, economic and sustainable performance. Originality/value The reliability and validity measurements confirmed that both SL and environmental and social performance are appropriate for manufacturing industries. This study provides evidence of the positive relationship between SL and lean manufacturing, lean manufacturing and sustainability performance, as well as the partial mediate effect of lean manufacturing on the relationship between SL and sustainability performance, which are the additional contributions to research in academic field. The results confirmed the positive relationship between transformational leadership and lean manufacturing. The results reported that there is difference of lean practices between automotive and nonautomotive companies, and between companies which implemented lean program less than five years and above five years. The structural relationship result reported that transformational leadership has effects on lean manufacturing whereas SL has no effect on lean manufacturing, which asserted the previous study in which one leadership model is more appropriate for success within lean implementations.

Purpose – Manufacturing firms consume energy and natural resources in highly unsustainable manner and release huge amounts of green house gases leading to many economic, environmental and social problems; from local waste disposal to climate change. Consciousness about these issues has lead to a new manufacturing paradigm of environmentally conscious manufacturing (ECM). There exist many social, legislative, policy, economic, internal, and environmental factors which can motivate and/or force industry to adopt ECM. The purpose of this paper is to identify the drivers for ECM, developing a model of these drivers using statistical analysis and testing the model using structural equation modeling (SEM) technique. Design/methodology/approach – The basic steps of methodology are ECM driver development, survey instrument development, data collection, model proposition, and model validation. The main data analysis approaches are exploratory factor analysis, confirmatory factor analysis, and SEM to develop a model of drivers and validating the same based on the data collected from the manufacturing industry. Findings – The reliable, valid, and tested model has three types of drivers – internal, policy, and economic. It has been found through hypothesis testing that internal drivers for the implementation of ECM are positively related to policy and economic drivers; and policy drivers are positively related to economy drivers. This research is expected to help government and industry in developing policies and strategies for the successful implementation of ECM. Practical implications – The novelty of this study is that it provides the relationship among the drivers which can be leveraged by the managers to focus on the root drivers for smooth and effective implementation of ECM. Originality/value – This paper provides new theoretical insight into the factors motivating the industry to implement ECM systems in the industry with special focus on manufacturing sector of emerging economies.
