Managing software quality in a very large development project

Control of quality remains a major challenge in software project management. Although there has been some research in the management of software development projects, very few studies have investigated the management and control of the quality of the software created, especially in large-scale development projects. During the development of OS/400 R.1 at IBM Corporation, thousands of programmers were involved in writing and refining millions of lines of code. Such an effort would fail without good software quality management. Using measurement derived from the literature, this study was able to verify the high quality of the OS/400 software based on rigid quality assurance strategies used in the project.
