Day by day the intensifying global competition is throwing challenges in the form of uncertainty and fluctuation in demand, necessity to provide wide variety to attract and hold the ever demanding customer. To survive and succeed under such competitive environment, organisations are forced to find and adopt efficient and effective ways for their operations. Organisations are seeking ways to increase the value of their products and services by eliminating unnecessary processes and practices from all systems. Lean manufacturing is a systematic team-based approach for finding and eliminating waste. The implementation of Lean manufacturing system helps organisations to reduce lead-time and inventory, improve quality, and achieve better on-time deliveries and utilisation of resources leading towards increased sales and profit through customer satisfaction. The Indian biscuit industry is the third largest manufacturer of biscuit in the world producing around 60% of the total production in organised sector and the balance 40% by the unorganised bakeries. In this paper, a medium sized biscuit manufacturing plant is studied under the framework of lean manufacturing system and observed that 5S, kaizen, quick changeover, TPM and TEI are some of the tools, which can be effectively used to improve equipment availability, reduce wastage of material and improve quality.
