iv&v

This paper introduces a new notion called Verification & Validation (V&V) Lifecycle Methodologies, examining what V&V is, and expanding its scope to the entire software lifecycle (much beyond traditional methods of software testing). V&V is recast in a much more holistic definition and approach, based on a rapidly maturing V&V discipline, solid empirical data, and recent innovations in metrics-based software quality and reliability management and engineering.
