-1 – Overview of Huatianmou’s experts in lean production management: Lean production management is a new production model that is driven by customer needs, focuses on eliminating waste and continuous improvement, and enables businesses to achieve significant improvements in cost efficiency and operational performance with minimal investment. Lean management is characterized by an emphasis on customers’ requirements regarding time and value; it utilizes a scientific and rational manufacturing system to organize production activities that add value for customers, thereby shortening production cycles and significantly enhancing a company’s ability to adapt to the constant changes in the market. - 2 - Lean production management is a production system that strives for inventory-free production, or reduces inventory to an extremely low level. The purpose of reducing inventory is to solve problems and cut costs, and low inventory levels require efficient processes as well as stable and reliable quality to be maintained. Lean process management involves integrating the principles and concepts of lean management, utilizing its techniques and tools to continuously eliminate waste and non-value-adding activities within processes, and to make ongoing improvements. This approach enables the creation of seamless processes that can respond swiftly to changes, while minimizing unnecessary time spent on tasks that do not add value, thereby reducing the overall time required for processes and allowing for faster response to customers’ needs. The eight wastes are common in businesses, and among all of them, logistics plays a key role. By starting with reducing inventory, the eight wastes include: overproduction, waiting time, transportation, inventory, processes (steps in production), movements, product defects, and neglecting employees’ creativity. Only by eliminating these issues at their root can a business achieve rapid growth. Lean production management is the expertise for eliminating these eight types of waste. In lean production, not all tasks are valuable; any equipment, materials, space, or labor that exceeds what is necessary to meet customer requirements constitutes waste. These wastes vary, and at the same time, the relationships between them are complex; one type of waste often gives rise to multiple other types of wastes. - 3 – Lean production management refers to the ability to produce only the amount needed at the time it is required; this is what we commonly call JIT (Just-In-Time production). The overall goal of JIT production is to completely eliminate unnecessary labor and waste. The role of standardization in lean production management is self-evident, but standardization is not a form of restriction or constraint; rather, it involves establishing the best practices within a company, so that anyone carrying out those tasks can do so to the best of their ability, achieving the highest level of effectiveness and efficiency. Moreover, standardization is not rigid or unchanging; standards need to be continuously innovated and improved. Based on the above understanding of lean production management, the steps for implementing lean production in factory enterprises are as follows: 1. Correctly identify value – While satisfying customers, the enterprise also reduces its production costs; this is the philosophy behind lean production. The lean philosophy unites the interests of businesses and customers, rather than adopting the adversarial approach of the past. At this stage, business leaders must first receive training to improve their ability to identify waste. Secondly, it is necessary to mobilize all employees to look for waste. To motivate employees, we generally implement 5S activities. Since the principles of 5S activities are very simple and their effects are quite evident, employees will quickly realize that lean production is a practical management technique. In this way, we mobilize everyone’s enthusiasm through practical actions, thereby reducing the ideological resistance to directly implementing lean production management. 2. Identify the value stream: Lean production management requires not only the participation of ordinary workers but also a systematic approach to its implementation. Therefore, it is necessary to analyze the current situation of the enterprise, and the tool for this analysis is the value stream map. Value stream analysis generally starts from within one’s own company, then extends forward to suppliers, and backward to the activities related to delivering goods to customers. Examine the value stream comprehensively from the end-user’s perspective, focusing particularly on the processes of handover between departments, as these processes often involve significant waste. - 4 - 3. Pursuing a “single stream”: Lean production management requires that all activities (steps) involved in creating value flow continuously, emphasizing an uninterrupted flow. “The very meaning of a \"value stream\" is \"flow,\" but entrenched traditional concepts and practices, such as departmental division of labor (waiting during transfers between departments) and mass production (work-in-progress waiting next to machine tools), prevent the value from flowing as it should. Lean production management considers any form of stagnation to be a waste for a company, calling on everyone to fight against the ideas of departmentalization and mass production. The most powerful tool in the struggle is “unit production.” 4. Pull: “Pull” means designing inputs and outputs based on customer needs, so that users can obtain what they need at the exact time they require it. With this pull-based approach, users or those at the downstream end of production can obtain what they need just like from a supermarket shelf, rather than having products that users are not interested in forced upon them. The pull principle eliminates premature and excessive investment by ensuring a direct correspondence between production and demand, thereby reducing inventory levels and work-in-progress on site, and **significantly shortening the production cycle. 5. Perfection: The goal of lean manufacturing is to \"provide customers with the highest quality value through a perfect value creation process [including design, manufacturing, and support throughout the entire life cycle of products or services]\”. Since the external market environment is in constant change, companies must also undergo continuous transformation; therefore, \"perfection\" remains an eternal goal, but it is a pursuit that continues endlessly. It will create a company that remains vibrant and continuously improves. Steps for using lean production management tools: Step 1, 5S activities on the shop floor ； Step 2: Value stream analysis ； Step 3: On-site unit production modification ； Step four: progress control, drive production ； Step 5: Quick switch ； Step 6: Continuous improvement by IE ； Step 7: TPM – Total Productive Maintenance ； Step 8: TQM quality improvement ； Placing the quality-related tool of TQM at the end does not mean that quality is not given importance; it’s simply because implementing lean production does not have to wait until quality improves first.
