1. Root Cause Analysis (RCA) 2. Implement Statistical Process Control (SPC) 3. Standardize Processes and Work Instructions 4. Enhance Supplier Quality Management 5. Continuous Improvement Through PDCA Cycle

Reducing defects in a new manufacturing process is a critical .Some of the important actions can be 1.Track KPIs like defect rate,and customer satisfaction metrics 2.Focus on Process Design and Control 3.Create detailed process maps to visualize workflow, potential problem area 4.Use SPC to check variations from target values 5.Develop WI's to ensure consistency in operation 6.Carefully select suppliers based on Q performance, reliability and work with them to improve their quality through training, technical assistance 7.Provide employees with necessary skills to perform their tasks effectively. 9.Rigorous inspection and testing to identify and rectify defects early in the process 10.Conduct RCA to determine the cause of quality issue

Conduct a Fishbone Diagram (Ishikawa Diagram) : Visualize potential causes of quality issues. Perform a Pareto Analysis : Identify the most common defects or issues. Investigate Root Causes: Analyze data, interview employees, and observe processes. Implement Process Changes : Modify workflows, procedures, or equipment to address root causes. Provide Employee Training: Educate staff on new procedures, quality standards, and defect prevention. Enhance Quality Control Measures: Introduce additional inspections, testing, or certification processes. Interdepartmental Collaboration: Foster open communication between production, quality control, and other relevant teams. Collaborate with suppliers to ensure quality materials and components.

There are many steps involved, one of the best way is to follow six sigma process. The goal of Six Sigma is to achieve a level of quality where there are only 3.4 defects per million opportunities.
