As Dod contract specialist, you receive a purchase request to procure non-commercial services value over $1,000,000 for a very critical and urgent requirement. The budget cannot exceed your initial funding. You need to motivate the contractor to control expenses more efficiently. Which motivational strategy is described?

Options:

1. Schedule based motivation factors
2. Performance based motivation factors
3. cost based motivation factors
4. supply chain motivation factor

I am debating between 1 and 2. Which option is the correct response?
