Lean practices are a set of principles aimed at improving efficiency and reducing waste in various processes. Originating from the Toyota Production System, these practices focus on maximizing value for customers while minimizing resources. Key concepts include continuous improvement, value stream mapping, and just-in-time production, which help organizations streamline operations and enhance productivity. By implementing lean practices, businesses can identify and eliminate non-value-added activities, leading to faster delivery times and lower costs. This approach encourages a culture of collaboration and problem-solving among employees, fostering innovation and adaptability in a competitive market.
