Improvement framework (PDCA cycle)
1. Plan
Clear improvement direction: such as improving OEE (overall equipment efficiency), implementing 5S management, etc.
Develop KPI indicators such as per capita output, unit energy consumption, yield rate, mold change time, etc.
Establish a special team: a cross functional team composed of departments such as production, process, equipment, and quality.
2. Do (execute)
Conduct on-site diagnosis: Identify bottlenecks through "walking management" or "value stream mapping analysis".
Implement improvement measures, including layout adjustments, process optimization, automation upgrades, etc.
Training and promotion: Enable employees to understand the significance of improvement and actively participate.
3. Check
Data collection and comparison: Use data dashboards to record changes in key indicators before and after improvement.
Problem review: Regularly hold improvement summary meetings to analyze results and shortcomings.
4. Action (processing)
Standardization: Write effective improvement measures into SOP and work instructions.
Promotion and application: replicate successful experiences in other production lines or factories.
Continuous improvement: Set the next round of improvement goals and establish a continuous optimization mechanism.
