Penerapan CMMI-Dev dalam Mengukur Maturity Level Proses Pengembangan Perangkat Lunak dengan SCAMPI-C (Studi Kasus: Software House XYZ)

Abstract

The success of software development is determined not only by the quality of the final product but also by the maturity of the processes that support its development. Organizations with well-defined and managed software development processes are more likely to deliver products that meet quality, cost, and schedule objectives. Software House XYZ is a small software development company that has operated for approximately 15 years. Despite its extensive experience, its software development activities are still conducted using informal and undocumented processes. This condition makes it difficult for the company to evaluate process performance, identify process weaknesses, and determine improvement priorities. Therefore, an assessment of the software development process maturity is needed to provide a clear understanding of the current process capability and to support continuous process improvement. This study aims to assess the maturity level of software development processes at Software House XYZ using the Capability Maturity Model Integration for Development (CMMI-DEV) Version 1.3 and the Standard CMMI Appraisal Method for Process Improvement Class C (SCAMPI-C). The assessment focused on seven Level 2 process areas: Requirements Management (REQM), Project Planning (PP), Project Monitoring and Control (PMC), Supplier Agreement Management (SAM), Process and Product Quality Assurance (PPQA), Configuration Management (CM), and Measurement and Analysis (MA). Data were collected through interviews, observations, and document analysis and mapped to the Specific Practices (SPs) of each process area. The results indicate that Software House XYZ remains at Maturity Level 1 (Initial). Capability achievement scores were 60% for REQM, 75% PP, 70% PMC, 58.33% SAM, 87.5% PPQA, 50% CM, and 31.25% for MA. Among the assessed process areas, only PPQA achieved Capability Level 1 (Performed) with a Fully Implemented rating, while the remaining process areas were categorized as Partially Implemented to Largely Implemented. The study also identified several process weaknesses that hinder the organization from achieving a higher maturity level. Based on these findings, improvement recommendations were developed and prioritized using the Pareto Principle (80/20). The results show that the priority order for process improvement is MA, CM, PMC, PP, SAM, REQM, and PPQA. These recommendations are expected to serve as a guideline for Software House XYZ in systematically improving its software development processes and progressing toward a higher level of process maturity
