AN EMPIRICAL INVESTIGATION TO EVALUATE THE RELATIONSHIP BETWEEN SUCCESS FACTORS OF LEAN SIX SIGMA AND WASTE MANAGEMENT ISSUES by Harsimran Singh Sodhi, Doordarshi Singh, Bikram Jit Singh Abstract: Purpose The purpose of this research paper is to evaluate the relationship between critical success factors (CSFs) of Lean Six Sigma (LSS) with the various issues contributing towards waste management in manufacturing SMEs. Design/methodology/approach In this study, 121 SMEs of manufacturing sector have been extensively surveyed, to assess the relative impact of level of waste and the waste management techniques implemented in the manufacturing sector. The correlations between various major factors of LSS with the various major issues contributing towards waste management in Indian SMEs industrial organizations has been identified.Findings After reviewing the literature it has been found that LSS is the waste management technique which addresses most of the major issues related to the industrial waste. Therefore the correlation between the various issues and the factors of LSS has been developed through the calculation of Cronbach Alpha and Value of Reliability and variability measure for all the constructs. Afterwards Discriminate Validity Testing has been done and Pearson Correlation Matrix has been formulated. Multiple regression analysis has also been done in order to access the significance of major contributing factors of implementation of LSS. Originality/value This study provides the relationship between the issues related to the higher waste in manufacturing sector with the major contributing factors of a waste management technique i.e LSS considered in present study. Keywords: Lean Manufacturing; Six Sigma; Lean Six Sigma; SMEs.
The Effect of Six Sigma approach as a tool for strategic cost management on achieving competitive advantage: The case of Jordanian industrial public shareholding companies by Inaam Al-Zwaylif, Lilian Taher Abstract: The study aimed at investigating the effect of six sigma criteria on competitive advantage for Jordanian industrial public shareholding companies. Data was collected from a random sample using a questionnaire specially designed for this purpose. Multiple regression analysis was utilized to test the hypotheses using the stepwise approach. The study revealed that Six Sigma criteria as a whole significantly affect the competitive advantage; and each criterion was significant and explained a significant amount of the variance in a competitive advantage. The findings of the study also showed that Jordanian industrial companies apply Six Sigma criteria at an average level, and they are interested in the competitive advantage at an average level. Keywords: Six Sigma; strategic cost management; competitive advantage; industrial companies; Jordan.
SUCCESS FACTORS AND BARRIERS TO IMPLEMENTING LEAN IN A HOSPITAL SETTING: AN EMPIRICAL STUDY IN KOSOVO by Lura Rexhepi Mahmutaj, Priti Shrestha Abstract: The purpose of this article is to address the factors that bring successful implementation of lean, and the main challenges impeding the uptake of lean in the hospital setting. Qualitative case study approach was used to explore the applicability and implementation of Lean in a hospital setting. The findings indicate that the key success factors include management support and acceptance for need for Lean by understating lean philosophy, principles and methods, while the main challenges are resistance to change within staff and support from government. The research study is the confined focus on a hospital setting in Kosovo in a single department. This will be rectified by carrying out further interviews and/or surveys in the future and making this investigation a longitudinal study. The case should be extended to other departments within the hospital, and to other service firms to support the findings and have wider generalization. The results will help other hospitals and service firms to understand success factors and barriers to implementing lean. Keywords: Lean; Lean implementation; Critical success factors; Challenges; Hospital setting.
