PurposeIn this paper, the implementation of lean manufacturing and six sigma practices among Malaysian manufacturing SMEs toward achieving sustainable performance was investigated. Furthermore, intention to implement IR 4.0 technologies among manufacturing SMEs was also examined.Design/methodology/approachThe primary data were collected from 120 manufacturing SMEs across Malaysia using organization as the unit of analysis. The data were collected using the six-point Likert scale questionnaire.FindingsBased on research findings, about 86% Malaysian manufacturing SMEs implement 6s. Nevertheless, lean and 6s has an influence on sustainable performance among Malaysian manufacturing SMEs. Only about 32.5% Malaysian manufacturing SMEs have the intention to implement IR 4.0 technologies. This study results imply that IR 4.0 technologies implementation among Malaysian manufacturing SMEs are still at infant stage though lean and 6s concept is known by the manufacturing SMEs.Research limitations/implicationsThis study has implications for future researchers to explore application of IR 4.0 technologies among manufacturing SMEs. Therefore, there is need to create awareness about the application of IR 4.0 technologies suitable for manufacturing SMEs in order to remain sustainable for local and foreign competitors. From the perspective of system theory, there is an interconnection network across each department in a whole system. More so, sustainable performance can continuously change and improve the system in any organization.Practical implicationsFrom the view of SMEs policy makers, this study should be use to encourage SMEs to adopt technologically inclined practices. Accordingly, this research recommends government bodies to help support the implementation of sustainable practices due to their sizes and inadequate resources involved. Therefore, the role of government in providing suitable policies that could be beneficial to manufacturing SMEs toward achieving sustainable practices cannot be overlooked. Through proper government support, Malaysian manufacturing SMEs will be able to survive both locally and internationally and also gain competitive advantage.Originality/valueThe main contribution of this paper includes integrated effect of lean manufacturing practices and six sigma implementation among manufacturing SMEs and prioritizing implementation of IR 4.0 technologies to be executed by manufacturing SMEs.
