Transition of Independent Verification and Validation Activity and Refined Concept at the Mature Age

Abstract

This paper describes how Independent Verification and Validation (IV&V) has grown at the Japan Aerospace Exploration Agency (JAXA) and how the activity was devised over two decades. However, as the development process for aerospace products matured over the decades, the value which IV&V needs to provide has changed currently. Hence, JAXA IV&V refined the concept of IV&V to accommodate mature software products. Definition of IV&V and also the narrow definition of independent, verification and validation are introduced in the paper. The paper also introduces the challenges and aspiration to support the refined concept.
