Software product quality control

En savoir plus sur le livre

Quality in software is context-dependent and varies according to stakeholder goals. To develop high-quality software, a clear specification of quality is essential, but this specification can become outdated over time. Continuous quality control is necessary for ongoing evaluation of a product’s properties against updated quality goals. This guide assists in establishing and executing continuous quality control within your environment. It begins with an introduction to quality, distinguishing between process and product quality, and defining key quality-related terms. The discussion then moves to quality models, which serve as the foundation for quality control, detailing how to plan for desired product qualities and ensure their delivery throughout the software lifecycle. The main concepts and techniques of continuous quality control are presented, including the quality control loop and techniques such as reviews and testing. Each chapter includes sample scenarios, and a dedicated chapter explores various applications of quality control techniques in industrial settings. This resource is designed for practitioners in software engineering and quality assurance, helping them enhance processes, plan for quality, and implement advanced quality control techniques. It is also valuable for students and lecturers in computer science, particularly in courses focused on software quality, maintenance, and assurance.
