A key characteristic of non-conforming products or services is that they do not conform to the specifications in the contract. This means that the delivered goods or services fail to meet the established criteria, standards, or requirements that were agreed upon by the buyer and the seller. Non-conformance can encompass various aspects, such as deficiencies in quality, functionality, or performance compared to what was specified in the contract.

This concept is important in procurement and public buying because it directly impacts the evaluation and acceptance of goods and services. It may lead to disputes, require corrective actions, and ultimately affect the overall success of the project or contract management. Addressing non-conformance is vital for ensuring compliance with contractual obligations and maintaining quality assurance in the procurement process.

The other options pertain to characteristics that do not necessarily indicate a failure to meet contract specifications. Meeting contract specifications signifies conformity, ahead-of-schedule deliveries can be beneficial but do not address compliance with specifications, and discounted rates relate to pricing rather than product or service quality conformity.
