1.提出變更申請目的
2.AP 頭頭同意
3.附上變更軟體資料、測試報告等等。交付資料管制人員處理。
4.資料管制人員，檢查申請人所付資料是否符合?
要進入正式區軟體庫中的檔案是否與申請項目相同
要討論的是如何確認申請人所附檔案是正確的(第 4 點)：
1.申請人比對正式區軟體庫內容並產生差異檔 - DiffData1
2.資料管制人員依申請人申請，比對正式區軟體庫內容並產生差異檔 -DiffData2
3.比對DiffData1 與DiffData2 內容是否一致
問題來了，Source Code 是可以這麼做，但若是非Source Code (如COM/DLL) 要如何管理呢?
subversion 的diff 檔比不出來呀，解法是產生檔案的checksum 去證明是兩者一致，
如你去網路Download 檔案，也都是會看到檔案提供者在網站公告chksum ，讓你知道你下載的檔案是正確未被篡改過，要產生Checksum 有很多種方法，普遍是用MD5，那只要可以利用Subversion 找出差異檔並產生每個檔案的MD5 並產生報表，申請人與資料管制人員都利用這種方式進行變更管裡，問題就解決了。
