Which of the following is an exception to requiring a competitive process?

Sole source procurement is a recognized exception to the requirement for a competitive process because it occurs when a specific supplier is the only feasible source for a required product or service. This might be due to the unique nature of the goods or services offered, intellectual property rights, or previous contractual obligations that prevent competition. In such cases, conducting a competitive bidding process would be impractical or impossible, making sole source procurement a necessary approach.

In contrast, mass production, public auctions, and open bid requests all involve competitive processes where multiple suppliers can participate, laying the foundation for fairness and transparency in procurement. These methods aim to enhance competition and generally yield better prices and terms for the purchasing entity, which is contrary to the sole source situation where competition is not feasible.
