ABSTRACT
Lean thinking is a business idea that was developed in Japan. The primary contribution of lean is the discovery and elimination of waste. Companies use lean to retain their competitiveness by increasing system productivity and process quality. This paper focuses on the benefits of implementing lean-based sustainability on a comprehensive process used in an automation business, starting with quoting a new project, designing the products, manufacturing, programming, client training, and finally handing over. The goal is to use Value Stream Mapping (VSM), one of the important sustainable lean thinking methodologies, to improve the organization's process by minimizing waste and non-value-added processes. First, the process's current value stream map was created using personal interviews, observations, and secondary data from the firm. Following that, a future value stream map based on lean thinking ideas was proposed to improve total lead time for manufacturing and value-added time. Based on the final result, VSM is a helpful and relevant tool that may help managers conceptualize different types of wastes and defects. The results reveal that using various lean thinking techniques reduces the time, material, money, and other wastes caused by the present non-improved process, and this had an impact on the environmental, social, and economic aspects of sustainability.
