A Pilot Study: Opportunities for Improving Software Quality via Application of CMMI Measurement and Analysis

This paper presents a study to analyze software defect detection effectiveness at different systems development test phases of the products developed in REHIS (Radar, Electronic Warfare, and Intelligence Systems) Division of ASELSAN Inc., a CMMI v1.3 Level 3 Organization, and recommends a practical guidance to process improvement efforts at CMMI Level 3 organizations for systems development. In this study "Defect Escape Ratio" measure that had already been defined at ASELSAN REHIS Division for software development process effectiveness is used to identify software items for further analysis. "Defect Detection Effectiveness" measure is introduced to improve the effectiveness analysis of the systems development verification and validation activities. A pilot study is performed for the analysis and gathered results are evaluated for guidance in the further process improvement efforts.
