Best Practices

1. Regular audits - Weekly or bi-weekly consistency
2. Rotate auditors - Fresh eyes find more
3. Take photos - Visual evidence of progress
4. Follow up on actions - Close the loop
5. Celebrate wins - Recognize improvements
6. Post results - Transparency drives improvement

Constraints

• Audits should be constructive, not punitive
• Include area workers in the process
• Document all findings objectively
• Track trends over time
