  • Best and Final Offers (BAFO)

  • Emergency Purchase

  • Single Source Procurement

  • Sole Source Procurement

  • Pilot Program

View Answer & Explanation
Correct Answer: Option A -

Emergency Purchase

Explanation:

An emergency purchase is justified when there is an immediate threat to public health, welfare, or safety, or to prevent severe damage to government property.

A department forgot to submit a requisition for standard seasonal supplies, and they are now out of stock just as their busy season begins. The department requests an emergency purchase to avoid downtime. How should the buyer proceed?

  • Process as an emergency due to the operational downtime risk

  • Deny the emergency request because poor planning does not constitute a valid emergency

  • Process as a sole source to expedite delivery

  • Approve it as a single source exception

View Answer & Explanation
Correct Answer: Option B -

Deny the emergency request because poor planning does not constitute a valid emergency

Explanation:

Failure to plan properly by a department does not legally constitute an emergency. Emergency exceptions are reserved for true, unforeseeable threats to health, safety, or property.

Which of the following scenarios is the most valid justification for a Sole Source procurement?

  • The requested vendor offers a steep, limited-time discount

  • The requested software is highly preferred by the IT department

  • The requested item is patented and manufactured by only one vendor who has no authorized resellers

  • The current vendor is locally owned and heavily supports the community

View Answer & Explanation
Correct Answer: Option C -

The requested item is patented and manufactured by only one vendor who has no authorized resellers

Explanation:

A sole source procurement is strictly used when a single vendor is the ONLY source that exists in the market capable of meeting the requirement, such as with exclusive patents or original equipment manufacturer (OEM) restrictions.

A municipality decides to buy all its future police radios from Motorola, even though Harris and Kenwood make similar radios, in order to ensure seamless compatibility and reduce training costs. This is an example of a:

  • Sole Source

  • Single Source

  • Emergency Purchase

  • Request for Qualifications

View Answer & Explanation
Correct Answer: Option B -

Single Source

Explanation:

A single source procurement occurs when multiple viable suppliers exist, but the agency intentionally chooses one specific vendor for reasons such as standardization, compatibility, or maintenance efficiency. It requires strict legal justification.

During a Qualification-Based Selection (QBS) process, the procurement officer successfully ranks the firms. The agency begins price negotiations with the highest-ranked firm, but they cannot agree on a fair and reasonable price. What is the buyer's required next step?

  • Cancel the solicitation and start over

  • Ask the top three firms to submit priced best and final offers (BAFOs)

  • Formally terminate negotiations with the top firm and open negotiations with the second-ranked firm

  • Accept the highest-ranked firm's price because qualifications matter more than budget

View Answer & Explanation
Correct Answer: Option C -

Formally terminate negotiations with the top firm and open negotiations with the second-ranked firm

Explanation:

In QBS, if a fair and reasonable price cannot be negotiated with the highest-ranked firm, negotiations must be formally terminated with that firm, and the agency then proceeds to negotiate with the second-ranked firm.
