Which acquisition type is the least preferred according to FAR subpart 6.3?

The least preferred acquisition type according to FAR subpart 6.3 is "Other than Full and Open Competition." This designation reflects a fundamental principle of federal procurement that emphasizes the importance of promoting competition in acquiring goods and services. Full and open competition is aimed at fostering a marketplace where various suppliers can compete, typically leading to better prices and enhanced innovation.

When an agency opts for "Other than Full and Open Competition," it indicates that there are specific circumstances or justifications that prevent the use of a competitive approach. This might include situations where only one source is capable of meeting the agency's needs, or where urgent circumstances preclude the time required for competitive offers. Such a method limits opportunities for competition, which is why it is seen as the least preferred choice.

By contrast, options such as full and open competition, competitive sealed bidding, and simplified acquisition procedures are generally favored, as they align more closely with the government's goal of maximizing competition and minimizing the potential for favoritism or unfair advantages in the procurement process.
