What is lean manufacturing? Why is it important?
Lean manufacturing is a methodology that focuses on minimizing waste within manufacturing systems while simultaneously maximizing productivity. Also known as lean production or lean, is based on several specific principles, including Kaizen, or continuous improvement. Some of the benefits of lean manufacturing can include reduced lead times, reduced operating costs, and improved product quality.
Five principles of lean manufacturing
The principles of lean manufacturing represent a powerful framework that can revolutionize the way businesses operate, leading to increased productivity, reduced waste, and improved overall performance. By implementing these principles, businesses can unlock new levels of success and competitiveness in today's fast-paced market.
Identify value
Manufacturers must identify what their customers identify as valuable to continuously optimize production toward those criteria.
Map the value stream
Having identified value, manufacturers can evaluate processes to determine which elements add value and which steps are wasteful.
Create flow
Manufacturers should ensure that products move smoothly between process steps without bottlenecking or intermediate inventory.
Establish pull system
Inventory is considered one of the biggest wastes in any production system. Establishing a pull system where orders are produced as demand is generated, rather than producing stock in anticipation, can increase efficiency.
Continuously improve and perfect
Lean production manufacturing means continuously improving processes to increase efficiency further and reduce waste.
How can lean manufacturing be implemented?
Automation
Lean principles built into automation software for the factory floor promote root cause analysis. Finding the hidden bottlenecks and causes of lost time is no longer a manual process thanks to Industry 4.0 and smart manufacturing. This allows everyone from plant floor operators to plant management and manufacturing executives to collaborate and continually improve their overall factory performance.
Continuous improvement
Kaizen is a foundational principle for implementing lean and continuous improvement in manufacturing. Japanese for “change for better,” Kaizen is a long-term approach and manufacturing philosophy that focuses on eliminating waste, improving productivity, and sustained, targeted continual improvement. Kaizen implies that small, incremental changes routinely applied over time will result in significant improvement opportunities.
Supplier relationships
In a lean manufacturing environment, integration and coordination between suppliers and customers are essential to create an efficient value chain. To achieve this, you need to encourage the exchange of information and resources, as well as aligning goals and processes. By managing the relationship with your suppliers and customers in a lean environment, you can improve operational efficiency, product quality, customer satisfaction, and competitive advantage.
