Fault-Based Analysis: Improving IV&V Through Requirements Risk Reduction
Point of Contact	Jane Huffman Hayes hayes@cs.uky.edu
Dates	October 2001 - September 2004
Problem	There is never enough time or money to IV&V everything. We have only high-level knowledge of how the potential existence of specific requirements faults increases the risk of NASA projects. We have only high-level knowledge of how specific IV&V techniq ues (requirements tracing, code analysis, etc.) contribute to improved NASA system software reliability and reduced risk.
Objective	Building on prior research by Miller, Hayes, and Mirsky [40], develop a requirements fault taxonomy for NASA systems (expandable to a general one). Develop a taxonomy of IV&V techniques. Examine requirements analysis techniques to determine what faults they can detect. Develop guidance for NASA IV&V based on the results.
