Boeing has adopted the Supplier Quality Surveillance (SQS) process as a proactive approach to improve partnership with Suppliers, combine Boeing business surveillance activities and improve reporting of Supplier process health.

The SQS process consists of three tools; Product Assessment (PA), Quality Process Assessment (QPA) and Manufacturing Process Assessment (MPA). These surveillance tools will support Boeing in the monitoring of Suppliers in a planned / scheduled manner without impeding product delivery. Surveillance activity is determined based on supplier performance and risk to Boeing. The SQS process will provide valuable opportunity for development and improvement of Supplier's manufacturing, Quality systems and support processes. SQS does not replace Boeing Quality Management System or Special Process activities, audits, recognition or source inspection activities.

SQS activities are performed by Boeing's Supplier Quality Specialists at the Supplier or Supplier's subcontractor facility under the contractual General Provisions addressing Boeing right of surveillance and review of goods and related procedures, practices and processes (e.g, GP1).
