The key principles of Lean thinking are:
1. Value: Focusing on creating value for the customer and eliminating any activities that do not contribute to that value.
2. Value Stream: Identifying the entire value stream or the set of processes and activities required to deliver value to the customer.
3. Flow: Ensuring that value flows smoothly through the value stream without delays, interruptions, or bottlenecks.
4. Pull: Adopting a "pull" system where products or services are produced or delivered based on actual customer demand rather than relying on forecasts or pushing products to customers.
5. Perfection: Striving for continuous improvement and constantly seeking perfection by eliminating waste, reducing variability, and embracing problem-solving approaches.
6. Respect for People: Recognizing the importance of employees and their skills, knowledge, and expertise, and creating a culture that encourages their involvement and contribution to improvement efforts.
7. Continuous Improvement: Practicing continuous improvement by regularly identifying and eliminating waste, reducing process variability, and seeking new and better ways to deliver value to the customer.
