They are based on the concept of continuous improvement, which is the idea that small, incremental changes can have a significant impact on overall performance. Lean principles focus on eliminating non-value-added activities, streamlining processes, and reducing inventory. By doing so, businesses can reduce costs, improve customer satisfaction, and increase profitability. Lean principles also emphasize the importance of collaboration and communication between all stakeholders in order to ensure that everyone is working towards the same goals. Finally, lean principles emphasize the importance of measuring and tracking performance in order to identify areas for improvement.
