In current scenario the fashion industry (industry 4.O) needs to satisfy the various needs of customer in the aspect of quantity as well as quality of the products. In traditional methods the apparel industry used basic sewing machines for all operations with the help of man power so on that time to introduce different styles in the apparel is very difficult. In recent days the automation as well as improved techniques known as industrial engineering concepts is applicable in the field to improve productivity as well as quality to overcome the competitive market. Manufacturing of garment involves number of operations in different departments. In apparel sector to improve productivity as well as quality one must concentrate on machine, method, material and man. So the industrial engineering concepts will cover and manage the all above said factors and help to improve the productivity as well as quality of the products that will satisfies the consumer needs. This paper is going to discuss about the existing (manufacturing) methods in apparel units and help them to improve productivity by applying the one of recent techniques such as Capacity Study, Work study, Time study, Operator Performance, Follow-ups, Work-in-Progress and line balancing and they are already proven techniques to improve the productivity in different industries.

Manufacturing processes undergo various transformations based on technological advancements and industry expectations. At initial times, during the period of first Industrial revolution, products were getting manufactured using human capabilities and skills. Then, electrically-driven motors, machines and conveyors were used. Now in the fourth Industrial revolution, Industries are equipped with automation, robots and cyber-physical systems. But adopting such technologies requires a high capital investment which cannot be accommodated by some start-ups. In this research paper, a case of a start-up which manufactures straws and vessel scrubbers in an eco-friendly manner as an initiative towards sustainability has been discussed. The key product of the company is biodegradable straws which are manufactured from coconut leaves through a set of processes. The scope of the research is to develop a labour-intensive process planning model. Managing contemporary issues is a big task for the company because of the dynamic nature of the environment. In this case, the demand for straws changes based on customer preference and accordingly, the manufacturing processes need to be revised. Hence, developing a rigid planning model is not an effective solution, so that, flexible manufacturing process needs to be developed. There is always a scope of improvement towards betterment and optimization in a manufacturing process. It is not necessary that the improvements should lead to drastic results. Japanese manufactures who bring the Toyota Production System (TPS) believe that small improvements in a continual basis will fetch better results in terms of quality, efficiency and lead time reduction. Once the model is developed, areas of improvement to optimize the resources are found out and iterations of process planning model were carried over to improve the efficiency. Through the study, it is found that the development of a flexible process plan is required to compete with the changing business scenarios.
