The system has the goal of improving the comprehensive strength of manufacturing technology, ensuring the sustainable development of the company, enhancing the level of smartification and promoting the development of the company’s smart manufacturing.    Kaifa Lean Guidelines     The establishment of Kaifa’s lean production maturity evaluation standards has laid the foundation for the Kaifa lean production management system. The use of maturity surveys serves to find gaps, set targets and encourage improvement. There are no unified industry standards for lean maturity in the EMS field. Kaifa used excellent performance models to formulate its own unique lean maturity standards. The lean maturity standard makes its value and positioning in the industry chain clear, unifies lean language, and involves the whole value creation process from when an order is received right up to the final delivery of the finished products. The lean standards are further divided into nine modules; lean policy, lean KPI, demand management, supply management, production workflow (method), production technology management, site management, continuous improvement mechanisms, and lean talent and organization The nine modules are based on the principles of strategic orientation and being based on processes and systems and are structured to display lean maturity standards with a total of 36 KPI indicators, 86 qualitative evaluation details that make up a grand total of 122 standard conditions. It meets the requirements of the company’s current situation and its future development trends.   Kaifa Lean Maturity Standards Structure     The implementation of Kaifa’s lean maturity standards have consolidated EMS core capabilities, strengthened the leading position of competitive industries, and promoted lean production management systems. The “learning lean, benefiting everyone” concept of lean production has been realized through technological innovation and improvement, the integration of internal and external resources, and the breaking of organizational boundaries. In addition to this, a professional and efficient product manufacturing and delivery system has been set up, and the company’s overall operating efficiency has been improved.
