List two supply chain levers that would help resolve the following financial issues:

1. Gross profit margin has improved significantly from last years results even though net profit margin has declined.

2. Our COGS is very competitive, but our EBIT margin continues to erode.

3. Direct costs at our factory are 20% higher than our budget expectation.

4. Suppliers are getting paid faster than last quarter.

5. Our inventory has been growing year over year even though we have had increased sales.
