CPPB - Certified Professional Public Buyer Specification Writing Questions and Answers

Question 1

A public agency needs to procure a new fleet of vehicles. The specification states, "The vehicles must be reliable and easy to maintain." Why is this language problematic for a competitive solicitation?

Accepted Answer

It is subjective and not measurable, leading to evaluation ambiguity.

Answer

Terms like 'reliable' and 'easy to maintain' are subjective and cannot be quantitatively measured or consistently evaluated across different proposals. A good specification must use objective, measurable criteria (e.g., 'mean time between failures of not less than 5,000 hours,' or 'routine maintenance shall not exceed 1 hour') to ensure all bids are evaluated fairly against the same standard.

Question 2

A city's public works department is creating a specification for a custom-built water filtration system for a new treatment plant. The city's engineers have provided detailed drawings, material requirements, and component dimensions. Which type of specification is being used, and what is the primary risk to the city?

Accepted Answer

Design specification; the risk is that the city bears responsibility if the resulting system fails to perform as needed.

Answer

This is a design specification because it dictates precisely how the product is to be constructed. The primary risk shifts to the public agency; if the contractor follows the detailed design exactly and the system does not function correctly, the contractor is generally not at fault because they did not design it. The city has an implied warranty that its design is adequate.

Question 3

When is it most appropriate for a procurement professional to use a 'Brand Name or Equal' specification?

Accepted Answer

When it is the least acceptable method, but no other type of specification can adequately describe the agency's needs.

Answer

While not the preferred method, a 'Brand Name or Equal' specification is used when the agency cannot develop a sufficiently detailed performance or design specification. It uses a known product as a benchmark for quality and function but must include 'salient characteristics' to allow other brands to compete if they can meet those essential features, thereby promoting competition.

Question 4

Which of the following is the primary purpose of establishing a Qualified Products List (QPL) prior to a procurement?

Accepted Answer

To streamline future procurements by pre-testing and approving products that meet required standards.

Answer

A Qualified Products List (QPL) is a list of items that have already been tested and certified to meet the specification requirements. This streamlines the procurement process for future purchases, as bidders offering products from the QPL do not need to submit them for testing with their bid, saving time and resources for both the agency and the supplier.

Question 5

A procurement department is developing specifications for new playground equipment. The specification requires that all metal components be made of '3-inch diameter, schedule 40, galvanized steel pipe' and that the structure must 'withstand 90 MPH wind loads.' This is an example of which type of specification?

Accepted Answer

A combination specification

Answer

This specification includes elements of both design and performance. It dictates specific materials and dimensions ('3-inch diameter, schedule 40, galvanized steel pipe'), which is characteristic of a design specification. It also requires a specific outcome ('withstand 90 MPH wind loads'), which is characteristic of a performance specification.
