Which of the following methods could be used to reduce the cost of a service...

Cost reduction without reducing service scope can be achieved by:

Implementing an in-house first response program (1): Staff address minor issues before calling the vendor, reducing service calls.

Extending the contract length (4): Vendors often offer reduced rates for long-term contracts.

Increasing house calls (2): Increases cost, not savings.

Financing the contract (3): Impacts payment terms, not cost reduction.
