1. Standards are essential for a strong manufacturing process and must be applied correctly. Standards can come from external sources like suppliers or internal sources like production data. All manufacturing activities should be standardized through documents like standard operating procedures and work instructions. 2. An effective control system is necessary to ensure standards are followed. The control system should be designed to replace human auditors with technology where possible. Data collection is also important for the control system. 3. Developing employees is the third key factor in maintaining a strong manufacturing process long-term. Employees should be treated as partners through training and loyalty-building rather than subordinates. Their feedback can help improve the manufacturing process over time.
