資訊技術已成為公司經營業務的推動者，而軟體系統亦已成為任何企業的主要需求之一。軟體系統可作為支持和簡化企業業務流程的工具，所以就必須符合使用者的品質要求。有效的軟體開發流程對符合品質需求是必要的。如果能按既定時程與成本，且符合用戶的需求，則可以將軟體開發流程視為有效。 本論文以一家印尼銀行業務公司為研究個案。該公司在競爭激烈的市場中運營，除需要維持既有客戶外，亦須吸引更多新客戶， 因此軟體品質需要有穩定的進步成長，而能力成熟度整合模式（Capability Maturity Model Integration, CMMI）2.0版是一個可用於軟體流程改善的框架。
本研究旨在更好地理解CMMI-DEV的實作過程。由於CMMI模式結構組成相當龐大，因此本研究以連續表述作為CMMI的實作導入方法。首先個案公司必須視當前軟體開發過程的狀況，來選擇適合的實踐領域，並確定其導入之優先順序。本研究使用CMMI規劃藍圖，透過定義業務目標和問題來選擇實踐領域，並使用SCAMPI C作為評估軟體開發流程的成熟度和能力水平的評估方法。本研究結果可做為CMMI-DEV V2.0導入公司改善其軟體開發流程與提升軟體品質的參考。

Information technology has become an enabler for a company to operate its business. The software has become one of the organization's primary needs. The software's role as an instrument for supporting and simplifying business processes in an organization. A single software should have excellent quality to satisfy the client. An effective software development process is necessary to produce good quality software. The software development process can be classified as effective if finished on time, cost-effective, and following user requirements. A case study involving a company that engaged in the banking business was done. This company operates in a very competitive market. This company needs to maintain its customers as it gains fresh customers. Therefore its software quality needs to be steadily improved. Capability Maturity Model Integration (CMMI) version 2.0 is a framework which can be used for software process improvement.
This study is undertaken to gain a better understanding of CMMI implementation. As CMMI constitutes an enormous structure, continuous representation was used as an approach for CMMI implementation. The company must define and prioritize which practice area is most appropriate for the current conditions of its software development process. This study uses CMMI Roadmap for selecting the practice area by defining business goals and problems. SCAMPI C is used as an appraisal method to measure the level of maturity and capability of the software development process. This study uses a questionnaire-based method to collect data. The result of this research is a recommendation that can lead to software quality improvements. The recommendation is formulated based on CMMI-Dev version 2.0
