What is a 'red flag' indicator in supplier performance that requires action?

• A. On-time deliveries.
• B. Excellent quality records with no defects.
• C. Accurate invoicing and transparent communication.
• D. Repeated late deliveries, nonconforming goods, or noncompliance with contract terms.

Answer: (D)

In supplier performance, a red flag indicator signals potential risk and requires action to prevent bigger problems for cost, reliability, or compliance. The option that best fits this is the one describing repeated late deliveries, nonconforming goods, or noncompliance with contract terms. These issues point to ongoing performance problems that can disrupt supply, erode quality, or breach agreements, so they trigger escalation and corrective actions such as root-cause analysis, corrective action plans, supplier development, or even supplier replacement if the issues persist.

The other signals are positive indicators: on-time deliveries show reliability, excellent quality records with no defects reflect consistent performance, and accurate invoicing with transparent communication indicates good fiscal and transactional hygiene. While these are desirable, they don’t represent risk that must be mitigated.
