SUMMARY

• Quality Assurance is the most important job for
  large scale
• fabrication of the detectors.
• A very good QA procedure was followed during
  fabrication of
• STAR-PMD.
• The procedure for QA of ALICE chamber fabrication
  is almost
• finalized and it is in the similar direction
  with improvements.
• 4. We are almost ready with all the setup for
  Quality Assurance.
