1) Why the specific problem occurred?

1.2 Why the instruction defined the lot could be released?
The lot should be held at 8150 with two reason：a. need to waiting for QA result b. summary issue (F0880UDNM error)
When supervisor received PE’s mail (the mail introduced the summary issue not effect any product quality), supervisor informed QC to release lot to next process.
1.3 Why QC ignored the hold reason of waiting for QA result?
Due to there was only one hold tag attached on ASPEN. Pack QC considered the QA result of G152880 has passed when QC got the released message (summary issue) from M&P supervisor. So pack QC released lot to next process.

2) Why the problem was not detected before shipping to customer?
2.1 QC should write two tags to notice two hold reasons and then dispose, but only attached one hold tag.
