Reliability Models and Metrics for Space Shuttle Maintenance Position Statement

The article of record as published may be located at http://dx.doi.org/10.1109/ICSM.1992.242520The use of software reliability models as an aid to software maintenance, with applications to the Space Shuttle on-board software, will be described. In addition to supporting the maintenance function, the use of reliability models throughout the life of the software supports other functions such as reliability assessment, design feasibility assessment, and management of human and computer resources. By assessment we mean an evaluation of how well the software meets reliability goals
