The Improvement Process for The Software Development and Requirements Management to Achieve Capability Level 3 of CMMI

This research proposes the improvement process for software development and requirements management for a small and medium company to achieve capability level 3 of CMMI 2.0. The process was proposed to be executed by the waterfall process model and scrum-based agile. The authors developed the improvement process and support tool. The proposed process was applied to use in the home-loan service software development 2 projects. The evaluation of the proposed process was analyzed by comparing it to past project two projects. The result showed that the projects that applied the proposed improvement process had a better outcome 34.34%. The SCAMPI evaluation of the proposed process was taken by three experts and the result showed that the capability of the proposed process was 91.63% and the user satisfaction was at the good level with score of 4.37. From the experimentation that was conducted with two software companies, it was obvious that the proposed improvement process had significance to enhance the software development process to achieve capability level 3.
