我國政府在2004年將提升資訊軟體品質列為資訊服務業主軸措施，以宣示政府全力推動資訊軟體品質制度之決心，作為推動國內資訊服務業「大型化」及「國際化」的基礎工程，協助資訊服務業者提升其生產力，增強其承接大型與複雜專案之能力。而國內資訊軟體產業配合國家政策及世界趨勢紛紛導入由卡內基美隆大學內的軟體工程學院(Software Engineering Institute, SEI)所提出的「能力成熟度整合模式」(Capability Maturity Model Integration, CMMI)。依據SEI的統計資料，我國至2011年通過CMMI的評鑑的有113家，全球排名第10名，而屬於高成熟度的第四階只有4家，第五階只1家，佔總家數的4.4%，低於全球平均值的7.1%，相較於中國5.4%，印度24.5%，日本9.8%，南韓13.3%，都略顯相對落後鄰近國家。而依據SEI(2012)的統計資料，由成熟度等級3到成熟度等級4平均約要25個月，要進入高成熟度並不容易。
而本論文之研究是提供國內有志於進行ML4之組織在制定流程程序書時參考使用，以節省過程時間。在論文中所提出的程序是整合CMMI中「組織品質與流程績效(OPP)」及「量化專案管理(QPM)」兩個流程領域在同一個程序中交叉進行。在制定流程程序時是使用IDEF0嚴謹的模式，由上而下將程序依資料產生的先後順序合理性，安排程序。每一程序都有輸入的資料、作業的人員及輸出的資料。論文中在第一階分有4個作業集，有2 個作業集是屬OPP的範圍，另有2個是屬QPM的範圍。在第二層展開共有11個作業，這與一般在ML2、ML3一個程序對應一個CMMI的流程領域有所不同。

The government of Taiwan labeled promoting the quality of information software as key measures of information service industry at 2004 for four purposes. First, show the government’s staunch determination to promote the system of information software quality. Second, being foundation constructions of promoting domestic information software becoming large-scaled and internationalization. Third, assist information servicer to raise its productivity. Forth, strengthen information servicers’ ability of contracting large-scaled and complicated cases. Domestic information software industries match up with national policy and worldwide transcend, bringing in Capability Maturity Model Integration (CMMI), which is addressed by Software Engineering Institute (SEI) of Carnegie Mellon University. According to statistics date of SEI, in Taiwan, there are 113 companies have passed CMMI evaluation, raking 10th in the world. There are four companies rank forth level of high maturity, and only one company ranks fifth maturity level, which are 4.4% of all the companies, lower than the world average, 7.1%. Comparing to neighborhood countries, 5.4% of China, 24.5% of India, 9.8% of Japan, 13.3% of South Korea, is apparently fell behind. According to statistics data of SEI (2012), it costs about 25 months to progress from rank third of maturity to rank fourth of maturity.
The research of this dissertation is to provide reference materials for domestic organizations who want to get to rank fourth of maturity are defining procedure documents, to save time.
Two process areas, OPP, and QPM, were integrated into one procedure, which involves intersecting processes. Utilize strict IDEF0 to set process procedures, setting from top to down, and then set procedures according to the output order of data. Among four processes in the dissertation, two processes belong to scope of OPP, the other two processes belong two QPM. There are eleven processes broke down at the second level, which is different from ML2 and ML3 one procedure corresponding one CMMI process area.
