Benefits of Sole Sourcing
Sole sourcing has a positive impact of shortening the acquisitional process:
- A reduced decision cycle, i.e. time required to award contracts.
- Lowered administrative costs, i.e. procurement process reduced to a minimum.
- Prices reflecting the best value.
- Better promoted small business participation.
