Documents have typically been main conveyers of information and the authoritative source for system verification and validation (V&V) plans and activities.  Difficulties lie in the management of a document-based V&V process because there are inherent interdependencies between integration and test schedules, test environments, requirements and verification activities.  Additionally, as systems complexity increases, system-level (V&V) is often no longer performed using dedicated, localized test environments.  Emulators, simulators, test harnesses, and/or software required may be widely distributed and involve a variety of test engineers and equipment distributed around the country.  Each facility may have test equipment and software of varying degrees of fidelity.  No single facility may exist that brings together the highest fidelity equipment.  Distributed facilities may have only loose network connections between them, if any.

Mr. Tim Brady
NASA, INCOSE TGCC Vice President
