SCAR

SCAR commonly refers to a Supplier Corrective Action Request, a formal request issued to a supplier to investigate, contain, and correct a nonconformance associated with the products or services they provide.

What a SCAR is

A SCAR is a documented request from a customer organization (such as an OEM or tiered manufacturer) to a supplier that typically requires the supplier to:

• Describe the nonconformance and its scope
• Implement immediate containment to protect ongoing production or fielded product
• Perform root cause analysis of the issue
• Define and implement corrective and, where applicable, preventive actions
• Provide objective evidence of completion and effectiveness

SCARs are often managed within quality management systems, supplier quality portals, or integrated MES/ERP and are common in regulated industries such as aerospace, pharmaceutical, and medical device manufacturing.

Where SCARs are used in operations

In industrial and manufacturing environments, SCARs appear in:

• Supplier quality management: Linking incoming inspection results, nonconforming material reports, and supplier performance metrics.
• Compliance workflows: Providing documented evidence of how supplier-related nonconformances are controlled and corrected.
• MES/ERP integration: Tying nonconformance records and holds to specific lots, work orders, purchase orders, and supplier records.
• Risk management: Feeding into supplier risk ratings, approved supplier lists, and escalation processes.

Response expectations for a SCAR, such as timing for containment, preliminary analysis, and final corrective action, are usually defined by contracts, purchase order terms, or customer quality clauses, rather than by a single industry-wide rule.

What a SCAR is not

• It is not the same as a general internal corrective action request, although the processes are similar.
• It is not a complete supplier quality program, but one tool within a broader supplier management framework.
• It is not by itself evidence of regulatory compliance, although SCAR records may support audits and assessments.

Common confusion

The acronym SCAR can be used differently across organizations:

• Supplier Corrective Action Request: The most common meaning in manufacturing and regulated supply chains.
• Supplier Corrective Action Report: Sometimes used interchangeably, emphasizing the documented response from the supplier rather than the request itself.

In practice, both usages refer to the same basic process: documenting, investigating, and correcting supplier-related nonconformances in a traceable way.

Link to aerospace and other regulated sectors

In aerospace and other highly regulated industries, SCARs are often tied to customer-specific quality clauses and sector standards. Organizations may define required response times for containment actions, preliminary root cause analysis, and final corrective actions, and may integrate SCAR handling with incident, concession, or deviation processes. Digital systems are frequently used to ensure that SCAR records are complete, time-stamped, and traceable to affected parts, lots, and configurations.
