(from Software Verification and Validation: Its Role in Computer Assurance and Its Relationship with Software Project Management Standards, by Dolores R. Fujii, NIST Special Publication 500-165) Having thus carefully distinguished the two terms, my advice to V&V practitioners was then to forget about the distinction, and think instead about V&V as a toolbox, which provides a wide range of tools for asking different kinds of questions about software.
This view is common in many software engineering textbooks, and is misguided.I’ll draw a better picture when I’ve finished analyzing the data from my field studies of practices used at climate labs.Many different V&V tools are already in use at most climate modelling labs, but there is room for adding more tools to the toolbox, and for sharpening the existing tools ( are the subjects of my current research).Therefore both validation and verification are needed throughout the lifecycle.Finally, V&V is now regarded as a coherent discipline: ”Software V&V is a systems engineering discipline which evaluates the software in a systems context, relative to all system elements of hardware, users, and other software”.
