The Cirrus Logic Quality Management System (QMS) defines how quality is built into every facet of the company’s design and development processes, as well as the systems that govern the manufacturing supply chain through fabrication, test and delivery. Our QMS guides how we measure and continually improve the degree to which customer requirements and the quality policy are satisfied. The efficiency and effectiveness of our QMS is reviewed on a regular basis. The Quality department participates in each Quarterly Data Review (QDR) where metrics are reviewed by senior management to assess the relevance and progress of the quality system. Actions pertaining to the quality system are assigned and documented at this review. An annual summary of internal audits is published by the Quality department and distributed to senior management. Findings are reviewed with each department manager for necessary corrective actions.
Cirrus Logic follows JEDEC standards (JESD46) for customer notification of product/process changes. Prior to customer notification, changes to datasheet, wafer fabrication, assembly, or test undergo a rigorous internal change management process.
