Internal Audit
Quality Audit performs regularly scheduled internal audits to assure compliance with established processes. These
audits are conducted by trained personnel who coordinate the audits with area managers. The results of the audits are
documented; corrective actions are documented and evaluated through follow-up audits. These audit reports are
forwarded to management for review. (GEN17.1)
Processes
Corporate Quality Plans are developed to identify suitable methods of monitoring and measuring QMS processes.
Corrective action is taken when unfavorable conditions exist. (GEN01.1)
Operations Quality consistently monitors the production process, at appropriate points, through statistical process
control methods. Corrective actions and preventive actions are implemented when necessary. (AM20-1)
Product
ADTRAN has implemented inspection and test points to ensure product requirements are met. Inspectors and Test
Operators work from detailed work instructions. Records are maintained on all inspection and testing activities.
ADTRAN performs functional and final testing to engineering released Acceptance Test Procedures (ATP). The
continuous flow lines at ADTRAN utilize the concepts of all personnel as inspectors to visually detect workmanship
defects prior to packaging.
Inspection and test records are recorded by the performing function and maintained electronically on the ADTRAN
internal network. Records include, but are not limited to: product identification, quantity of product inspected,
inspection procedures followed, person performing the test and inspection, date of inspection and/or test, number, type,
and severity of defects found.
Product requalification / retesting of released product is accomplished by Quality Assurance / Operations on a periodic
basis. “Retesting” is conducted in a more robust environment than the original acceptance test. ( GEN10.3 and RE01)
All ADTRAN returned products are reworked, or repaired, and retested in accordance with the ADTRAN Engineering
Acceptance Test Procedures.
Software tests are conducted according to documented procedures and test plans. (EN10, PQ01)
Control of Non-conforming Product
Non-conforming material is reviewed and dispositioned by the Material Review Board (MRB). The chairperson of this
board is the Quality representative. Operations Engineering, Manufacturing Services, and Purchasing are also board
members. Other support personnel may be called upon as required. MRB dispositions are use-as-Is, Scrap, Repair, or
Return to Vendor. Standard rework that meets specification requires no disposition. All rework or repair is subjected to
inspection prior to continuing processing. Records of discrepancies are maintained on the ADTRAN internal network
and reviewed for trends as input for corrective and preventive action. (GEN13.1,GEN13.2 GEN13.3 and AM4.13-1)
Analysis of Data
Data and information recorded in quality records are compiled and analyzed periodically to determine trends in the
performance and effectiveness of the quality system and to identify opportunities for improvement Some data utilized
in this process comes from, but is not limited to, the following:
Customer Satisfaction Surveys
Field Performance Data
Internal Audit Results
Inspection Records
Corrective and Preventive Action Nonconforming Material
Manufacturing and Test Records
First Pass Yield and Delivery
Supplier Performance
Corporate Quality is responsible for coordinating these activities, and for reporting conclusions and trends to top
management. This is usually done within the framework of management reports and reviews of the quality system.
