When implementing lean manufacturing, factories should avoid short-sightedness and focus on long-term planning. No improvement is insignificant; seize every opportunity to improve, taking a step-by-step, pragmatic approach, paying attention to details, and starting with small steps.
1. Management decisions should be based on long-term principles, even if it means sacrificing short-term gains.
The same applies to implementing lean manufacturing; a long-term strategic plan is essential. Lean manufacturing cannot be achieved overnight. Toyota Motor Corporation in Japan implemented lean manufacturing through long and arduous exploration, from proposing the Just-in-Time (JIT) concept to making it an advanced production model.
Therefore, when implementing lean manufacturing, avoid short-sightedness and focus on long-term planning. No improvement is insignificant; seize every opportunity to improve-this is my humble opinion. Take a step-by-step, pragmatic approach, paying attention to details, and starting with small steps.
2. Establish uninterrupted operating processes to bring problems to the surface.
Uninterrupted operating processes refer to continuous flow production. Production processes are arranged according to the takt time of production per unit and the speed at which customers order products, ensuring timely fulfillment of consumer demand. After determining the production takt time, analyze the flowchart to identify which processes add value and which do not. Reduce non-value-added processes to improve process performance.

3. Implement a pull production system to avoid overproduction.
A pull production system is a customer-demand-driven system. Production plans and schedules are determined based on customer order volumes. The basic method for implementing a pull production system is Kanban management. Kanban is a method for the factory and suppliers to synchronize their takt time with the customer's.
4. Stabilize workload levels (production leveling).
To stabilize workload levels, conduct line balancing analysis to ensure that each process is balanced and that the production time of each unit is matched as much as possible.
5. Establish a culture of immediate pause to solve problems and prioritize quality management from the outset.
Instill quality awareness in every employee, conduct Total Quality Control (TQC) activities, solicit suggestions for improvement, and utilize the PDCA cycle to continuously improve process quality.

Effective standardization leads to continuous process quality improvement. Standardizing procedures enhances work and process efficiency.
7. Visual Management Eliminates Hidden Problems
Through the establishment of the 5S system, offices and factories are spotless, machines are free of dust, oil, debris, or dirt, creating a first-class, clean working environment and fostering a positive corporate culture. Visual management ensures clear item labeling, and Kanban management provides immediate visibility.
8. Use Reliable, Proven Technologies to Assist Employees and Production Processes
By continuously developing new products and utilizing advanced management techniques, the company enhances its independent innovation capabilities. For example, implementing Six Sigma design improves product quality, manufacturability (DFM), and reliability.

9. Cultivate Employees Who Thoroughly Understand and Embrace Company Philosophy into Leaders, Enabling Them to Teach Others
Strengthen the training of multi-skilled workers, ensuring every employee possesses the ability to assist team members. Simultaneously, cultivate team leadership skills.
10. Cultivate and develop outstanding talent and teams who believe in the company's philosophy.
Promote teamwork, cultivate excellent talent, and solve key and difficult problems within the company; build cross-functional teams to complement each other's strengths and maintain the company's effective operation.
11. Value the company's partner and supplier network, and motivate and assist them in improvement.
Strengthen supply chain management, value collaborative relationships with suppliers, and form a community of shared interests with them.
12. Visit the site in person to thoroughly solve problems (on-site inspection and verification).
Strengthen on-site management, implement the principles of on-site inspection, on-site verification, and on-the-spot verification, and thoroughly solve practical problems in on-site work as soon as possible. Managers must lead by example and be hands-on; without being on-site, one has no right to speak.
13. Avoid hasty decisions; base decisions on consensus, thoroughly consider all possible options, and execute decisions quickly.
Managers should strive for group decision-making, fully consider everyone's opinions, and once a decision is made, it must be implemented immediately; not only must there be decision-making power, but also execution power.
14. Through continuous reflection and improvement, make the company a learning organization.
