Modern manufacturing is under ever increasing pressure to develop solutions for highly complex tasks. In order to maintain the business survival in a highly competitive environment, it is vital to obtain customer satisfaction, which requires developing products with shorter lifecycles and higher quality meanwhile to reduce the production costs. In order to achieve such objectives a paradigm has been developed called “lean manufacturing”. However according to the literature, this tool has been widely used within the large companies, there is still an ongoing research to prove their applicability in Small and Medium Enterprises (SMEs). This paper aims to assess the feasibility of applying lean manufacturing principles within SMEs using survey in Uttar Pradesh. This study aims to explore the causes and obstacles of lean manufacturing in Uttar Pradesh’s small and medium-sized businesses. An 11.6% response rate was obtained from a survey that was distributed to 293 small and medium-sized enterprises (SMEs) in Uttar Pradesh in addition to their suppliers. The information collected through the questionnaires was examined using the statistical package for social science (SPSS) program. This research paper explores the implementation of Lean Manufacturing principles in Small and Medium Enterprises (SMEs) across various sectors.
