The paper describes a complete and industrially-validated model for quantitative evaluation of the quality of a software-based system, and examines the deployment of such a model within the development, management and quality processes of software production. The installation and operation of the model is described within a Quality Control Department responsible for assuring the attainment of reliability and maintainability requirements for the on-board software components of missile guidance systems. The model provides a framework for the quality analysis of both the software product and the development process, and supports measurements taken throughout the entire system lifecycle. Experiences are reported of the phased installation of the model via a carefully managed technology transfer operation, and strategies outlined for the definition of didactic support required to educate both project and quality managers and software developers in the operation and analysis of the model. In describing the observed benefits of use of the model, we discuss the future role in software certification of quality measurement technology. Finally, generalisation of the existing model is discussed to demonstrate its widespread application within critical systems development environments controlled by industry-standard methodologies.
