| Formalized Pilot Study of Safety-Critical Software Anomalies | |
| Point of Contact |
Robyn Lutz rlutz@cs.iastate.edu |
| Dates | December 1999 - December 2002 |
| Problem | Advances in NASA's capability to produce safe, reliable systems depend in part on our ability to more precisely characterize areas needing improvement. Analysis of in-flight, critical software anomalies is such an area. |
| Objective | This work characterizes safety-critical, in-flight software anomalies (using operations data from Cassini and other spacecraft) with a defect-analysis technology, called Orthogonal Defect Analysis, developed by IBM and used by major industries. A formal ized pilot study approach provides a sound, quantitative foundation to enable improvements, principally in testing. |
