| Interactive Software Fault Analysis Tool for Operational Anomaly Resolution | |
| Point of Contact |
Ken Chen kchen@ems.jsc.nasa.gov |
| Dates | October 2001 - September 2002 |
| Problem | Resolving software operational anomalies frequently requires a significant amount of resources for software troubleshooting activities. The time required to identify a root cause of the anomaly in the software may lead to significant timeline impacts and in some cases, may extend to compromise of mission and safety objectives. |
| Objective | An integrated tool that supports software fault analysis based on the observed operational effects of an anomaly could significantly reduce the time required to resolve operational anomalies; increase confidence for the proposed solution; identify software paths to be re-verified during regression testing; and, as a secondary product of the analysis, identify safety critical software paths. |
