Scalable V&V Effort Estimation for Ultra-Large-Scale Systems

Project planning requires early-on effort estimation. As such, predictions into the future are made with some degree of unavoidable uncertainty. It is likely that some of those predictions will be proven wrong. Thus, solid techniques and concrete procedures are needed to reduce the inaccuracy of estimates. This paper is motivated by practical industrial experiences. It presents a scalable technique that enables scalable effort estimation and is used within an industrial project. The approach determines the critical factors that have to be considered when estimating the V&V effort for systems.
