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.
