Systems?, The Fifth International Society of Science and Applied Technologies (ISSAT)
International Conference on Reliability And Quality In Design,. Las Vegas, Nevada,
USA August 11-13, 1999
Requirements for large information systems are not reliable if we interpret that
term to mean complete, consistent and current. A General Accounting Office examination
of 10 major systems shows deficiencies in generating complete requirements and in
keeping them consistent and current. Requirements analysis tools, formal methods,
and recursive development formats are beneficial but do not address organizational
and contractual issues. As an alternative to the current methodology we discuss
a figure of merit as the key requirement and giving the developer more responsibility
for trade-offs during development.
