Requirements Decomposition Analysis
Point of Contact Allen N. Nikora

Dates October 2001 - November 2003
Problem Requirements play a pivotal role in planning, selection, development, testing and operation of NASA's missions. Starting from mission objectives, requirements are successively decomposed. The correctness of this decomposition is critical, yet V&V of this crucial step is limited to manual inspection and pointwise testing, which are cumbersome and fallible (e.g., Mars Polar Lander).
Objective Rigorous lightweight analysis methods for requirements decomposition have been developed by the software engineering research community, and have shown promise in successful application to critical systems (e.g., rail transportation). This proposal willstudy their application to the V&V of spacecraft software requirements, to ascertain if, when and how they are suitable for use by NASA.
